All the studies focus on single-task performance. Indeed, typing random characters for several hours a day would lose my attention.
I don’t know of a study that estimates the maximum number of productive hours over a varied workload such as running a startup. There clearly is a limit, but it’s high — maybe 90 hrs/wk for motivated people.
In practice, it’s the neglecting of other things like relationships and exercise that kicks in before mental energy limits.
- xondono 7y agoThere’s a difference between productive and deep focus. Even if it’s a factoid, based on personal experience and anecdotal evidence from colleagues, 4h is a good approximation. I will admit though, that there’s a confounding variable here, that is how much your coworkers value your time. When I worked 4h or 6h workdays, everyone considered my time to carry a premium, so they avoided interrupting me if they could.
- EastLondonCoder 7y agoI do know people that can work extremely long hours and still be productive but they are quite rare. For a large majority of people a ninety hour work week, would be extremely counter productive at best but most likely dangerous for your mental health. https://www.popsci.com/work-week-hours-productivity/ https://www.popsci.com/work-week-hours-productivity/
- agumonkey 7y agoI'm curious about the nature of the 90hours per week too. Is it ~slow paced work, no rushing but constantly walking ideas and attempts ? Can they endure 90 hours of hard dead ends / frustration / disappointment ? Or is it 90hours of tangible progress (lets include small dead ends that provide nice references for more ideas) and pleasure ?
- unreal37 7y agoNewport's book puts the distinction between deep work and shallow work. Calling up restaurants and trying to get them to switch to your booking software is shallow work. Needing to sit down and program the complete back end of that booking software including testing by Friday is deep work. You can only do so much deep work before your reserves of energy are depleted.
- sonabinu 7y agoOne of the challenges of deep work is getting in the zone. Does the book go over that?
- wainstead 7y agoIf by "zone" you mean "flow," then yes; here's a relevant quote from Deep Work: > The connection between deep work and flow should be clear: Deep work is an activity well suited to generate a flow state (the phrases used by Csikszentmihalyi to describe what generates flow include notions of stretching your mind to its limits, concentrating, and losing yourself in an activity—all of which also describe deep work). And as we just learned, flow generates happiness. Combining these two ideas we get a powerful argument from psychology in favor of depth. Decades of research stemming from Csikszentmihalyi’s original ESM experiments validate that the act of going deep orders the consciousness in a way that makes life worthwhile." Newport, Cal.

- hyperpape 7y agoThe assumption that programming is deep work seems like a self-serving prejudice. Which parts of it are automatic will differ from person to person, but I imagine that a substantial majority of programmers will spend a substantial chunk of their programming work doing things that are shallow to them.
- unreal37 7y agoSince the OP starts off quoting Cal Newport's book "Deep Work", we need to differentiate between shallow work and deep work. Running a startup is a whole bunch of shallow work most of the time. Work where you have to get into "the zone" to get it done, that's not 90 hours per week. Or likely even 19.
