  Less is more. C'mon, we're all dying here. Finishing is a skill (per Derek Yu). All measuring devices have noise. Symmetry and continuity impart incredibly strong constraints on systems. A dollar isn't worth a dollar to everyone. I am probably overreacting or missing something. Most of the value can be had by delivering less than 100%. Many problems cannot be solved, simply changed into other problems. If my team succeeds then I succeed.
  • worker767424 5y ago

    • RhysU 5y ago
      These relate to physics/modeling. I am going to hand wave a bunch. If a system has to operate the same way under rotation/reflection, that strongly constrains what the system can be doing. Think crystals or isotropic forces or, in the day job, what should happen if you negate a feature going into a neutral network then retrain. Should it matter from which perspective you look at a thing? If a system is continuous then smooth changes to inputs should cause smooth changes to outputs. The system probably will be robust to small perturbations because they will result in small output changes. https://en.m.wikipedia.org/wiki/Turbulence#Kolmogorov.27s_theory_of_1941 https://en.m.wikipedia.org/wiki/Turbulence#Kolmogorov.27s_th... is something of an example.

  Bayes Theorem
  • system2 5y ago
    "When applied, the probabilities involved in the theorem may have different probability interpretations. With Bayesian probability interpretation, the theorem expresses how a degree of belief, expressed as a probability, should rationally change to account for the availability of related evidence." Well, that's a mouthful.
    • ahdh8f4hf4h8 5y ago
      The most important part of Bayes rule is the concept of Prior knowledge and Bayesian updating - new data should always be combined with your existing knowledge (starting with the "base rate"), based on levels of uncertainty. Closely related is the concept of conditional probability - how does the probability of something change as you include other information. It takes some studying to understand probability theory well, but it is very powerful once you start to think that way. Most of the garbage science reporting in the media would be fixed if reporters actually thought this way and honestly applied it.

  * Time is money. * Don't lie to the person in the mirror. Accept your shortcomings as they are. * Having few good work partners is better than a dozen work friends. * Trust is non-negotiable & irreparable. * Always have a plan B if you want to complete something. * Always remember Plan B shouldn't become your Plan A by default - stay ambitious. * No question is a bad question - (sometimes questioning the status quo makes a big dent) Also, something I always cherish from my advisor (translated from his native Japanese): "You relish your sucess when your mind is paired with immense hardwork, dogged determination, indomitable grit and the acceptance of possible failure at each step of the way.

  Happiness for me is building the future: learning new material, meeting other interested people, and working on my goals. On the other hand, I must live in the present.

  Not if sure if this counts as a mental model or not.

  Feelings wheel feelings wheel feelings wheel feelings wheel feelings wheel feelings wheel feelings wheel The groupings of the finest emotions within the 2nd group are immensely helpful... for instance, "successful" and "confident" are in the proud category. And to feel successful, first trust in your own ability, then work for others and when they trust in your abilities too, you are successful. Respected and valued are in the same subcategory. To feel respected, first value something, and if you can get an employee to value the same thing, then they truly respect you. On the anger side, disrespected and ridiculed are in the same subcategory, and they are similar, but disrespected is when someone devalues your orders, and ridiculed is when they make fun of your form(body). On the sad side, isolated and abandoned are grouped, isolated is when you're sad for being taken out of something(a group or a feeling), and abandoned is when you and the rest remain, but a person leaves it. I've been reprocessing my whole life with finer emotional granularity, and I recommend it, highly so!

  - Hanlon’s Razor: never ascribe to malice that which can be ascribed to ignorance or stupidity.

    Similarly, never assume you know the context. I tend to apply this while driving a lot, when someone is speeding past me. "Idiot! But, maybe his wife is in the middle of birthing his son and he is rushing to the hospital?", helps me keep calm when others act like idiots.

      Or: always focus on the intent. People do things for different reasons, but you should only judge them based on the intent. For example, all lives matter, sounds good, but what is the intent behind that? Is it really to signal that all lives matter?
      • guntars 5y ago
        Intentions can be very nebulous. We are not always aware of why we’re doing something and tend to come up with explanations after the fact. These can even change over time. Ultimately we can only guess at what happens in other people’s minds. Alternatively we can look at the effects of an action. To use your example, when someone says “all lives matter” it, among other things, alienates black people. IMO makes it a lot more clear cut.
        • baby 5y ago
          Unfortunately whatever you say you’re always going to offend someone. That’s why I think intention is what matters most, otherwise you’re just following an angry crowd into cancelling someone for no good reasons.

• binbag 5y ago
  The concept of 'sharpening the saw', which I (rightly or wrongly, but it works for me) take to mean taking time to stop and think alone about where I am with a [usually work-related] project/mission/goal, draw a line under progress to date, and think about where I'm going now and what's most effective at this stage given present circumstances. Related is the phrase "Plans are worthless, but planning is everything" (attributed to US General MacArthur). Take time to stop, recap, take stock, and plan your next moves. Refresh your thinking. The other model/technique I've used successfully over the years (or, at least, I think it contributed to the successes, but it's difficult to say with certainty) is affirmations, as brought into common discourse probably most effectively and controversially by Scott Adams of Dilbert fame.
  • binbag 5y ago
    Also! Sorry, but I have to add this one because I find it factors in quite often (unfortunately): "The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts." (Bertrand Russell nailing it.)
    • emmelaich 5y ago
      That can be overstated. Also Russell was a eugenicist, at least for a while. That puts an unpleasant spin on that. I prefer the somewhat related "everyone is a conservative about what they know best"

  I lean on my default mode network to find solutions and scrutinise my ideas. This means that I avoid committing to important decisions until I've at least had a chance to sleep on them. The next day I normally have a lot more clarity and confidence in the decision when it's right, or what is wrong when it isn't. I also don't stress if I can't find the answer to a problem. I try to keep the problem at the front of my mind but don't pressure myself to activally solve it. Very often, this results in what feels like an epiphiny, a shower thought, or the answer will come to me in a dream. Activally working to find those solutions would be difficult and success would be hit and miss, it's low stress and gives me space to work on something else in the meantime.

• tunesmith 5y ago
  I think I made this up: In order to get to where you're going, you gotta start with where you are. Also, form versus content in general. A bit of Bayesianism, enough to feel glad when I'm wrong as an opportunity to better update my own understand. And inspired by Claude Shannon's "surprise is information" insight, trying to notice whenever something surprises me as something that gives me valuable information. Helps a lot with debugging problems, where oftentimes a seemingly irrelevant "well that was weird" ends up being the vital clue toward understanding the system.

    • chrsig 5y ago
      As far as I know, I coined it for myself. It's possible I read it somewhere that I've forgotten and am not properly attributing it. It's something that I've had to learn the hard way, but has recently really been instilled in me. For a long time I'd jump to trying to learn a technology designed to work in a domain (e.g., learn erlang to try and write a distributed system), and I'd wind up just spinning my wheels, because I'd be trying to figure out too much all at once. Somewhat recently however, I wanted to get into ray tracing, and decided to use Go for my first attempt (a language I'm very familiar with, but not necessarily the best for the domain...though, it did make some parts of it easier!) If I'd jumped right into trying to use cuda, I'd never have gotten anywhere with it, because I'd just be lost in trying to figure out all of cuda's idiosyncrasies. Instead I was able to get pretty far with go, making a bvh tree, triangle meshes, textures, area lights, convolutional filtering. Once I'd gotten pretty far with it, I wanted to get some experience with k8s, and so I modified it to be able to run an arbitrary number of worker pods and send samples to an aggregation pod. Now that I've gotten some good experience in the domain, I've started to rewrite it in c++/cuda, where I can now make some more educated decisions, because I spent the time learning the domain first -- I know roughly what I'm building. Long winded way of saying I arrived at the saying because it's the only thing that's been effective for me.

  For the play to your strengths thing, that only works when you're in a market where you get to play to your strengths.

    Definitely agree. One of the heuristics I use is NPC vs PC. If it feels like something NPCs do or is a fetch quest I avoid it, delegate it, outsource it, etc. If it's a PC thing, then I do it myself.

      • muzani 5y ago
        Where I work, this routine stuff is handled by an ops team. But we have a saying that ops will have a different job scope every 6 months because it will be automated. The ops team gets plenty of respect and are probably the real PCs. However phrasing it as PC/NPC work does seem insulting. Even games are evolving into forms where everyone is the PC. To mess with the analogy even more, it's usually low level PCs that are tasked with rat hunting and fetch quests.

  It's better to be decent in a lot of areas than to be great in one area and terrible in another. If A, B, C, D is how much value you provide in different areas, you should try to maximize ln(A)+ln(B)+ln(C)+ln(D) rather than A+B+C+D. Also see "Law of diminishing returns", "All happy families are alike; each unhappy family is unhappy in its own way." In creative fields nobody knows what they're doing and most time and money is wasted. It's often as important to think about what thing to do as doing the thing. You will most likely provide great value to your company/work a few days of the year (the days where you implement some feature your customer really needs or where you fix some potential or ongoing big production problem) and most days you will provide break-even or negative value. Also see "Impostor syndrome". Always automate manual or boring processes. Do not think too much about ROI calculations, they don't work because productivity in creative fields is very non-linear. Instant feedback is very important for concentration and morale. If you're prone to anxiety, saving money and building skills allows you to act without fear of major setbacks. And most of the time it's better to ask for forgiveness than permission.

    • B-Con 5y ago
      In today's world, almost all jobs are moving more and more toward specialization. Being great at something is how you work and make a difference. You can outsource many of your weaknesses, from the mundane (ex, spelling: spellcheckers) to the complex (ex, accounting: hire an accountant). In contrast, my mental model is that it is only worth knowing a little or a lot. The middle ground is only useful when you are filling a gap. * If you know a little, you know enough to reason about the topic and identify how you can outsource your needs. eg, you know enough about accounting to pick and manage an accountant. * If you know a lot, that's your value add and you can provide that service. Where if if you know a "medium amount"... * you still need to outsource to an expert most of the time * or you can't find the right set of expertise to outsource to and you must fill the gap yourself.
• SuboptimalEng 5y ago
  I heard this recently from one of Justin Kan's YouTube videos and it's really shaped the way I think about my career. "Work in your zone of genius [not your zone of competence]." Simply put, it means to work on problems that: 1. you have a natural inclination towards 2. (and perhaps more importantly) give you energy For example, I am good at full stack web development because that is the first job I got out of college. If I want to "optimize my career", it would be best to continue down this path and apply for roles that fit my experience. But, unfortunately for me, building web apps is not something that "gives me energy". One thing that does give me energy is thinking about/playing video games. I've always spent my evenings watching GDC talks or game dev documentaries. After watching Justin's video, I decided to take a shot at making games[0] and it's been a very different experience from making web apps. Even after a full day of coding, I continued to think about how to make the game better! The key insight is that you get better faster when you work on stuff you have a natural inclination towards, and that gives you energy to work harder on those problems. The hard part is making the leap to work on these problems, even if the trade-off is super high. For example, should I continue down the FAANG path and have a good life with all those perks as a full stack developer, or do I follow my "zone of genius" and enter the gaming industry which is known for some extreme practices. Who knows, with the way gaming is shaping up (Roblox, MineCraft, Unity, Fortnite, Meta, etc.) perhaps switching to this gaming industry is actually the more optimal solution :P [0] https://github.com/SuboptimalEng/GameDev https://github.com/SuboptimalEng/GameDev

  In many cases good is not the opposite of bad. Our brain is fantastic evaluation and extrapolation machine. Often I find myself judging something on a 1 dimensional scale, where 'good' is at one end and 'bad' at the other. More often than not that's a gross over simplification, and not helpful as a mental model. The 2 dimensional model, bad vs not bad and good vs not good is, in many cases, a much better fit. (Of course reality has a lot more dimensions usually - you get the gist). To make an example, Elon Musk is not a genius or an idiot, he is likely both a genius and an idiot.

  Similar to the heuristic mentioned by op. For those who grew up in the “you can do anything you put your mind to” era. As self evident as this sounds, Accept your strengths and weaknesses. If something takes little to no effort, that’s a real good sign that it’s a strength if it takes a lot of effort, it’s probably not :)
• Barrin92 5y ago
  I avoid 'mental models' altogether because I think this notion that there is some sort of model world different from lived reality is weirdly dualistic and fortune cookie like. I think if you're faced with a problem the answer to that is having acquired proper integrated intuition through experience, not 'advice' in form of some model. Say if you're a runner, the better you get, the less you have a model like "I put the left foot in front of the right foot and breathe three times" you just learn what to do holistically. Or if you get better at chess, the less you rely on generic advice like 'the pawn is worth 1 point, the bishop 3", and the more you get a sense of a position that you can't express as some verbal model. The very best players can play 'without thinking'.

    This seems costly in learning / addressing new situations. Mental models can help avoid a lot of pain or give you options to approach new situations that you might not otherwise consider without trial and error. Sometimes watching a YouTube video makes a lot more sense than acquiring proper integrated intuition through experience. I don’t want my surgeon to perform my routine procedure using mental models. If things go wrong, I absolutely want her to apply mental models as she troubleshoots the issue.
    • Barrin92 5y ago
      I think it is costly but I'm just very skeptical about how much cost and trial and error you really can avoid when actually doing / building something. For example with the surgeon I would say it's really important that she is quick, pays attention and is calm and reacts to new problems. Speed itself is a huge thing because thinking doesn't help you if the world moves on while you're thinking. I think people underestimate how tactile and sensory most problems are, even 'intellectual' ones. Another example is John Carmack recently pointing out how useless it is to talk about the 'metaverse' in abstract terms. When really you need to understand how the nuts and bolts and gears are engineered and hang together. The people who really build things often stay intentionally away from generalized wisdom.

  I heard a variation of this in a podcast comparing the difference between various language learning apps: Easy things feel fast, hard things feel slow, but in the long run you'll get more from doing the hard thing. In the context of language learning, they were comparing apps like Duolingo to WaniKani (for learning kanji). In summary, your brain can sucker you into thinking it's learning something, when in reality you're not being challenged at all. Doing 100 multiple choice in a day can FEEL like you're learning a lot in a short amount of time, but picking an answer when it's in front of you doesn't test your recall. Being forced to recall 10 kanji from memory over 10 days will help you learn them more reliably. I think this lesson extends to almost any domain. You can fall into a trap thinking "I understand how to do X in theory, but actually doing it will take so much longer. It would be a waste of time for me to do something I already understand how to do." But in almost every case where you've thought that, once you dig in and actually do the thing, you will hit roadblocks that you have to work around, you'll feel discouraged and confused about why it wasn't straight forward, you'll commit things to memory because you're forced to, and when it's all said and done you will have a much deeper understanding than if you had optimized that task out.

  Knowing what we need to win an Oscar for. Used like “we don’t need to win an Oscar for that”. An area where extra effort doesn’t target the outcome you need. Put extra time into the area where you need to win the Oscar. What gets us into the newspapers. Don’t fuck that up. Add an interface. Where you know you need an answer, create the interface and a simple implementation. Come back later when you need it implemented better, now you know where that has to be and it’s already lined up to use the better version. Sometimes simple version is enough and you’ve saved the time. You don’t need a phd in that. Same as Oscar. Know where to focus learning. CAP theorem. Often people choose consistency without knowing they have. Or insist on unnecessary availability when consistency is crucial. You’re always choosing so make it conscious and make sure the view is shared. Specialisation is for insects. Learn D3 and ML and Kafka and PowerPoint and marketing.

    > people are not internally consistent There are those with cognitive dissonance, i.e. those who will actually verbalize contradicting thoughts. However there are also plenty of people whose thoughts are fully consistent and logical. That said, those people will still behave contradictory to their thoughts. > You won’t cajole people into reconciling their beliefs into a cohesive elegant whole Logical arguments won't work on persuading an illogical person, that's true. However you don't have to live with it. There are plenty of other options besides logical arguments. There's bribing, coercion, and manipulation. Emotional appeal being a really successful technique in the manipulation category. > .. and that includes yourself Indeed it does. Logical thinking is great, but primarily done by the left brain hemisphere. I often witness myself doing things while thinking to myself how this wasn't the plan and how I still don't agree with my actions. That's because my plan was made primarily by logical thinking with no extra steps. However there is plenty of manipulation I can do on myself. For example if I have cookies that I shouldn't eat, the more effective strategy is to throw them away the first chance I get (to increase friction, the right hemisphere seems to love laziness), as opposed to thinking that I can always keep myself from eating them with pure willpower.

  Avoid tail risks. In other words, try to avoid circumstances that can kill you or severely harm you, even if the risk is small. Means no riding bicycles, taking medicines with horrific side effects (unless I'm actively dying), surgeries (unless absolutely needed), skydiving, helicopters, and walking next to traffic.

    • DantesKite 5y ago
      It's the same reason you wear a seatbelt, even though most people don't get into more than 3 or 4 accidents over their entire lifetime. The point either isn't avoiding all tail risks, since you can't foresee them all by definition, but by reducing exposure such that you won't be ruined if/when they do happen.
      • tomcatfish 5y ago
        Yes, but tail risks definitionally include the WHOLE TAIL, which is infinitely long (including stuff like Quantum gibberish turning you into salmon while you read this). It's why we plan for risks, not tail risks, but the category Tail Risks is simply the category Risks with the most common ones subtracted out!

  Fermi method (1), sometimes called a Fermi estimate, is one of the most useful ways to improve the accuracy of our brains natural reasoning processes for both technical and non technical topics. It's actually a form of Bayesian estimation (2) and habituating the problem solving method helps enhance our brains in built inference systems. We all get an intuition of how things work and "feel", and by decomposing those feelings and intuitions into smaller pieces and rationally considering the likelihoods of those pieces we can improve them. By habitually doing this we can improve the brains natural estimation processes which improves our decision making ability. Lastly but importantly, the detail that separates the Fermi method from regular reasoning/socratic method/etc is estimation of the uncertainty of various assumptions. This can be used to figure out how to quickly get specific knowledge to drastically improve the estimation with minimal effort/time. Fermi used that last bit at the first nuclear explosion test to realize that dropping a few pieces of paper and seeing the distance they blew would give him enough info to get an accurate order of magnitude estimate of the yield onsite (3).

  You greatest strength will be the cause of your greatest weakness. Variations of this can be used if one quibbles on the use of 'cause', sometimes I just put it directly as your greatest strength is your greatest weakness assuming people will make the logical connections. The most easy to see example of this is in physical traits such as muscle mass, speed etc. Strengthening one trait invariably is the cause of weakening another. The same principle can be observed in organization, mental processes and so forth.

  Never let a bad decision get in the way of a good story. I'm always thinking about "Create vs. Consume" => make sure it's at least 50-50, aim for 80-20.

    • keyle 5y ago
      It's a tough topic to talk about, because I'm not religious myself although I was baptised and went through the motions of a young kid, going to church even through school. That said my grandfather told me once this saying, and that shocked me to this day as it appears to be valid to me, and he was the most atheist person I've ever known. One day I was very sad, very very distraught. And I prayed in tears, on my knees, and it somehow materialised. Again I'm not religious, I was lost, powerless and did the last thing I could possibly do. And I think it invoked a certain calm and focus which allowed me to follow through opportunities that led me out of the woods. Like any beliefs in life, YMMV. But that stuck with me, your prayers don't get lost to the woods.

  * Don't compromise my ethics unless there's a very good reason to do so. Small steps down a bad path can lead to being very far from who you want to be. * Progress not perfection. Instead of being paralyzed by indecision, choose the simple tasks that can make incremental progress towards an end goal. Repeated small steps towards a larger goal can get you very far. * Break large tasks into smaller tasks that are achievable. For me, this mostly takes the form of a daily "to-do" list that I try to complete. Also getting even rough time bounds on how much effort/money/time is involved in each helps prioritize. * Make sure to include fun/satisfying/interesting things in your day to day life. This might include doing the (perhaps unjustifiable) "fun" thing of learning a new language, learning some math, playing a video game, watching a movie, etc. Burnout happens not because of excessive work but because the work being done feels without end and because hope drains. "Fun" things help counteract that burnout and depression, especially when they're tied to the skill that you're using day to day, because it provides a positive feedback and gives you something to look forward to. It also gives myself permission to slack off because I know I'll be more depressed if I don't. * When a task seems insurmountable, watch, wait and learn. Sometimes things are impossible because I don't have a skill set or the tools to understand it. Other times it's because they are impossible with the environment/tools at hand, so re-assessing whether it's still impossible when the ecosystem around it has changed is a potential way forward. * Don't forget "life maintenance" tasks. Cleaning, showering, exercising, maintaining friendships, etc. These all erode my mental health if not actively maintained. --- I just want to specifically address your "play to your strengths" model. I still maintain that to be an effective human being, you pretty much need to know everything (at least to a certain depth) but this doesn't exclude the "T-shaked skills" of learning [0]. Often time the deep knowledge in one domain bleeds into another, allowing avenues into it that other people might not have. For example, electronics is a whole lot easier for me because I have a more solid math and programming background than someone who's learning heuristics on how to construct a circuit (I'm not knocking those heuristics, I'm just saying I have a way into it that helps me).

  One idea I employ often is to "increase the temperature" of the system, non-essential complexity, bureaucracy, excessive variation of materials, etc becomes more apparent through a lens of being more demanding than necessary so that the physical limits of the problem dominates the solution. Another idea I use is to mentally time travel and try to visualize how context-sensitive my decision/design/process is. Decisions that require a "superior" (or even accurate for that matter) understanding of the context I'd frown upon. Even if they are not mistaken and biased, to me, they promote a dynamic of continued survival through non-obvious and increasingly complex actions, rather than forcing a simple and obvious environment. Another is engineering with a bias for optimizing recovery first then reliability (sort of a minimax). So for example combined I would rather have a way to recover from broken code and produce a teaching moment than I'd try to prevent a developer from merging said code in the first place. I'd try to exercise a process to recover all data from backups in a timeline that the company would survive first rather than dedicate resources first for redundancy and leave said scenario for later due to its low probability. Take all of this in a "while there is value on the other thing, I value this more" wrap. I like models that would force the space to be simpler and more obvious.

  "If one human can do it, so can another". For when a task or acquiring new knowledge/skills seems like a monumental feat. "Success is the best form of revenge". Having never felt like I really fit in anywhere (except maybe at art school) throughout life, having people say I'd amount to nothing, people laughing at my shared thoughts/perspectives, being told what I'm doing is the wrong way, that my take on something is stupid even if I spent time researching and/or combined held knowledge/experience, finding out others think I'm weird for my takes and/or for being quiet... this comes across as angsty but it's been my reality for the last 32 years, and it's never fun or a good feeling to face. But boy does it feel good to have surpassed those low held bars and the high ones I've set for myself. Additionally, it feels good to say "I told you so" without ever saying it. Never seek revenge, just better yourself. It's more worthwhile. "Never chase". Whether it's money, someone you're interested in, and especially assets, among other things. If you're chasing, it's either too late or wasn't meant to be. "Do things from the heart and with a clear mind, never for luxury or money". If it feels right, is something you have interest or passion in, and reasoning says it's good to pursue, do it. Benefits will follow, whether that's money or otherwise. "Anything is possible, but nothing is perfect". Paradoxical, but a reminder to self that you can achieve more than you limit yourself to, but also a reminder that perfection is impossible. "Be kind, but not a pushover". "Be too nice and people will take you for a dummy". Manners, kindness, being polite, etc are important imo, but people will take advantage of that until you put your foot down.

  I think that "mental models" is not what you imply and others in this thread talk about. A more appropriate term would be [life | work | other] "principles".
  • Izkata 5y ago
    Strong agreement here. A mental model is a model you hold in your mind of how something works, and informs you of its usage, how it can fail, and how to fix it when it does. Mental models are about specific systems and are built over time as you interact with the system; it may not be a perfect representation of the internals but as a model it's good enough to use the thing. A simple example might be turning the wheel of a car in order to turn the vehicle. How far can you turn it? How fast do you need to turn it to make a given turn? How fast can you be going / how much do you have to slow down to make the turn safely? How about keeping going straight on the road, is holding the wheel still sufficient? When making a turn, do the wheels in the back of the vehicle follow the same tracks as the front wheels?
    • ablekh 5y ago
      I'm happy that we agree on this. Having said that, I would note that your example, while certainly valid, is IMHO of a too small scale (literally and figuratively - the latter with regard to complexity) to comprehensively illustrate the "mental models" concept. When I think about mental models, I'm thinking more about analysis frameworks typically applied to much larger and usually much more complex systems than technical ones, mostly sociotechnical and socioeconomic systems (e.g., open source ecosystem, startup ecosystem, innovation, science, corporations, stock market, finance, economy, policies, politics, society, history).

  This is my best. If you have a habit of seeing yourself as capable of more than you typically (or ever) do, you’re likely to continue at that lower level of performance because you can take comfort in your elevated self image. By believing that your best isn’t a hypothetical, but just an observation of what you’re doing, you have to accept the lower performance or actually try harder and achieve what you believe you can. This mindset helps me both push myself in all areas, and be more humble as well.

  I always use Occam's Razor: the simplest explanation is the likeliest. It's one of the foundations of how I think. I often see people spinning off with increasingly improbable theories as to why something happened, and I try to explain this principle, but it's surprisingly difficult to teach. It's a sort of circuit breaker that helps you think straight. I also use "assume good intent." This is similar to Hanlon’s Razor referenced elsewhere in this thread, it's a bit simpler though. Most people are trying their best. The modern world is extremely complicated. The result of "assume good intent" is that you have a bit more patience and empathy when working with others.

  Here's three: 1) "All things are ready, if our minds be so." - Shakespeare 2. Holon para ta moria (ὁλον παρα τα μορια). From Aristotle's Metaphysics. The whole is something beyond the parts. Commonly mistranslated as "the whole is greater than the sum of the parts" -- which misses the point completely. Mathematical understanding and metaphor is only one type of thinking, one way to understand a complete system. Valuable, for sure, but incomplete. The whole system -- e.g. a human, a team, an entrepreneurial opportunity with all its moving parts -- in its full expression and action, is beyond mathematics. Only your whole human mind can hope to comprehend it. 3) Companies tend to die -- but people tend to survive. People matter infinitely more. The most valuable thing of all is human relationships.

  “The efficiency paradox”[0], saw a TEDx talk as part of agile training, and this really hammered in the fact that it’s more important to get stuff done than to be busy, or “efficient” with your time. If you focus on finishing a few things you’ll get more done than if you make sure you’re busy with something all the time. This really has changed how I approach a lot of things in my everyday life, both inside and outside of work. Simple things like doing a load of washing here and there, and getting it done rather than trying to do a massive amount on the weekend, or washing some dishes as they come up rather than being efficient and washing all of them at the same time. In a work context, I guess it is more about not committing to too much work in a sprint, and ensuring there’s a bit of slack time so that multiple people can work on any items that get stuck, take more time than expected or similar. Developers helping out with testing where needed, ensuring quick code reviews, some extra pair programming and so on.

  One thing that has immensely helped me a lot in the last decade is to cross the bridge when you reach it. May be the most obvious thing to most, but I had this thing where I would sometimes argue or worry about things way into the future, like a month or months into the future. Maybe it was an advice or maybe I discovered it on my own but I see a lot of things don't happen anyway or just take care of themeselves or don't bother you as much as I thought at the time (also you could never predict pandemics in advance). The other thing is people say a lot of things and I just say sure and carry on even if it's something I don't fully agree with at the time. It's only when a person repeatedly asks me about it do I start taking it seriously and give it any thought. I think this small mental model has contributed greatly to my happiness

  asking "what's happening right now?", especially in social situations like meetings. it reminds me to look beyond what is being said, as opposed to why things are being said. It's also a good way to gain perspective on any rapidly changing situation where you could get caught up in the moment

  Smartwork and 10x is bullshit. There is time when you are able to be in the zone for hours vs times when you are just not able to focus for more than a few minutes. If you really want to increase your productivity optimize for prolonged focus and being in the zone.

  Not every day but I often use the following. 1. Regret minimisation framework. 3. Interesting and novel things happen at the edges; stay close to it and don't spend much time in the comfort zone. 2. Don't optimise for happiness; look for novelty, and contentment.

  Some heuritsics I use: - play to your strengths, being balanced sounds nice but end up being really unproductive / un-pleasant - be nice / kind / non-jugemental to people - spend time on the things you like, as time and practice pile up you will end up skilled in those domain - go for the things that are of interest to you, not for the trendy ones - time spend automating tasks is usually time well spent - taking a break to gather knowledge on something vaguely connected to the thing you are doing is never time lost - when you have been procrastinating something for most of the day, declare that you will not do it today and that it is okay, it will free your mind to do other things instead of leaving you stuck - try and do one, single and quantifiable, thing a day. With time they pile up and you end up doing a lot of things - the mind is good at critisizing something but bad at doing something from scratch: instead of trying to produce perfection, do a rough draft and then improve on it incrementaly

If not, don't say it. 4: Conflict is opportunity and a moment for deep connection. 5: Acquire the perspective to appreciate even the things I don't like.

  „Reduce complexity“ / „minimize balls you juggle at once“ That‘s very broad, but some examples: Keep the number of distributed PRs low. e.g. merge a PR that adds an aws policy via terraform early, so you can absolutely stop thinking about it. Finish easy, fast tasks first so you reduce the amount of things you need to think about. Actively decide against working on a semi-urgent task now/today, focus on it tomorrow morning or if your current task is fully done.

  As a trained economist, I feel every decision made should have expected value and include opportunity cost at least at a mental or back of napkin calculation. Everything compounds so make the highest EV decisions today. What this really drives home is how much effort to put into your full-time job where progression (and the rewards) are heavily influenced by thing you cannot control like office politics or the broader economy. Even if I don't get a promotion, a job switch should yield 20% every couple of years. I'll do the the bare minimum advised by my boss to get him to recommend a promotion, everything else is spent on my side projects which have potential to replace my job and multiple promotions. Live life too so block out time for leisure or recreation. Don't use this to analyse if you should watch a movie with your friends on the weeked or do work. Generally: EV = Probability of Outcome x Value of Outcome Cost = $ or time/labour/effort EV of next best opportunity (choice) forgone

  A few more (edit window is gone) 1. Good things cost money; if you use something daily/frequently then get the best tool money could buy. Corollary: Don't cheap out on tools when you hire a good craftsperson. 2. Optimise for time, not money. One is finite, other is not. 3. Money is means to lead a good life; don't continue to accumulate money just for the sake of it. 4. Resilience is a skill that can be developed. Seek risk, fail often to develop resilience. 5. Doing >> Talking a.k.a. "Talk is cheap show me the code." 6. Creation, by definition, requires breaking (or disregard) the rules. 7. Entropy always increases. You need to spend energy to just keep things in order.

  If we are talking about success, I think it is important to consider for whom you want to look successful. If you are in the wrong environment success might be meassured by your salary, your job title, the car you are driving or other silly things like that. For me success is only meassured by my own standards, namely: am I working on things that I like working on? Am I able to do them the way I want? Am I making the world a better place by doing so? Am I getting better at what I am doing?

  - Time well spent. I have a habit of debriefing at the end of every day. I ask myself if this day was sustainable. If I'd be satisfied with 100 more days like this one, it was a good day. - Giving to your future self. When I'm too tired to start something, I'll prepare my workspace and "ingredients" for the next day, a bit like a cook's mise en place. - A position of "fuck you". Free time and disposable income give you independence of thought and action. Peace of mind is the best thing money can buy. - Money as time. Measuring spending in "time at the office" makes you question what's really worth your money. - Evolution through mutation. Progress comes from experimentation. Try new things. Better risk an occasional bad meal than eat chicken nuggets for the rest of your life.

  When evaluating whether to buy something: is it worth the amount of hours of work that took me to be able to afford it? I know roughly how much money I make per hour (money into my bank account every year / how many days I work every year / how many hours per day I work). So, say that something costs 100£ and it takes me 3 hours to make that money; would I work 3 hours to buy it? Also when buying something: sometimes I feel like under a spell, really wanting to make a purchase. Then I just sleep on it. Usually the day after the spell is gone, and I can better understand if I really want to buy that something or not. When doing something new: I'm the kind of person that - when learning to draw - spends more time looking at the perfect paper and pencils than actually drawing. I'm sure some of you can relate. I enjoy this process, but the truth is that to learn to draw you don't need anything else than any piece of paper and any working pen/pencil. So, learn to recognise when you go too far off track and go back to actually learning how to draw. There will be a time to hunt for the perfect paper. If you don't want to go back drawing, maybe you didn't want it that much to begin with. When spending money: spending money on things (objects) is almost always less worth than it feels. Unless it's a tool that you use (e.g. a DIY tool, or a kitchen knife, etc). Spending money on experiences (traveling, concerts, etc) and learning (books, courses, etc) is almost always more worth than it feels. Especially, as an introvert, there is something inside of me that tends to dodge "experiences". To be happy: I learned this recently from the Dalai Lama. You should learn the difference between happiness and pleasure/desire, and prioritise the former. E.g. when looking for a job how ethical a company is and how good you'd fit is more important than the salary, job title, and prestige of a company.

    Most stuff I desire nowadays, are pretty cheap. I work as a consultant and self-employed. I don't know if I am making too much or I am happy with small things (e.g. a Mechanical Keyboard, some new 3D printing resin) which has a cost less than an hour for me. This presented with me a different problem. I have to instead look at life quality improvement it provides purely. Most products in market, are never absolutely perfect. One brand will offer you X but not Y, while other will do opposite. Then you end up not buying anything, but be burdened by thinking about it for some time. Then eventually, you just buy it to save yourself from mental tax. I also found it more rewarding to spend money on experiences; a new sport, a new hobby etc.

  When debugging: Somebody is always lying. I found that most of the time, a bug is the result of a misunderstanding. Once I've ruled out the most obvious things that could go wrong, I assume that every line of code is a lie. Doing x + y => print x, print y and print x + y (oh oh here is an overflow) Sending a parameter to a function => print arguments before the call and within the call (oh oh somebody is messing with memory and I'm reading garbage) This helps catching silent failures which causes problems down the line.
• springogeek 5y ago
  A couple of things I try to remember, when I work on things: (I didn't coin either of these) "'done' is better than perfect" It's easy to get caught in a trap of trying to "perfect" something. If it's good enough to call done, you can always improve it later if necessary. You do need to have some clear definitions for what "done" means for you though. "make it work, make it pretty, make it fast" This is adjacent to the first saying. I sometimes find myself trying to optimise something prematurely. This is a good reminder to wait until the [unit of work] is "complete" before I try to optimise it.

  In such a world of conflict, a world of victims and executioners, it is the job of thinking people, not to be on the side of the executioner - Camus This is more on thinking about current social / ethical topics. I know it might not be helpful for many, but I find I try to stop and think about it whenever I'm shaping my opinions.

  How do you define mental models in the first place? It seems the examples given by you and other commenters mostly fall into the category of sayings, as you rightly pointed out, which are (sometimes) useful but overly general and unfalsifiable claims.

  Nobody here seems to know what a "mental model" means. Wikipedia has it as "an explanation of someone's thought process about how something works in the real world", which I think is a good and succinct definition. Anyway, the important part here is "how something works". I am reminded of being in the 4th grade (about 10 years old) when a student made a comment about being fat meaning that a person eats too much food and it just collects in their belly - such an idea makes sense of the idea of someone being fat, but it isn't accurate. The real science behind being overweight involves a lot more. In technology, inaccurate mental models abound because these days most people use technology while few are completely familiar with how the technology works Browsing through the top comments though, it seems most here don't know or don't care what a mental model is. Or maybe they just followed OP's lead, which is more like a personal philosophy or a personal code of ethics, rather than a mental model. Ethics is a valuable pursuit in its own right, but I was rather disappointed to come in here expecting some interesting mental models of different technologies, just to be met with a discussion of ethics.

  My summary of the advice on this page: #1 Just do it - You are going to die. Life is short. Regret comes from the things you didn't try so just go, do the thing, climb the wall, do the hard thing, don't be comfortable. Don't let the perfect be the enemy of the good. #2 Seek novelty and your own curiosity - Interesting and unfashionable is where the real fun is. Seems to be an argument between whether you want to double down on strengths or be decent in a lot of areas. I think Scott Adams advice is best here I think you want to combine two or three things you are top 10% at into one thing you are the best at. Some interesting one liners: - people are not internally consistent look for revealed perferences by what people actually do - Finishing is a skill (per Derek Yu). - I am probably overreacting or missing something. (I'd call this Hanlons Razor) - "All things are ready, if our minds be so." - Shakespeare - Praise in public, criticise in private - Practice Observe, Orient, Decide, Act (OODA Loop) - Quantity first eventually results in higher quality.

  - The concept of "recruitment". The body recruits muscles to integrate them into motions, the brain recruits networks to execute cognitive tasks, humans recruit stereotypes and concepts from shared awareness to back their words up. - Evolution and gradient descent. Systems, including humans and society, evolve to maximize the value functions acting upon them. Whether that's income or getting along with others. - All linguistically-based mental models are just approximations, and there's countless valid ones. Optimize yourself to use the ones that are the most flexible, and benefit you the most. When you rephrase another person's words, you're setting up the stage for offering them an alternative model in your next sentences. - Socialization is a scaffold for the self, and closeness is the inclusion of others into our self-concept. You can't fix yourself alone, and the wrong people can easily break you. - Awareness of something is enough to incorporate it into your information processing. This goes for both metaknowledge and for psychosocial dynamics.
