Here is my double-edge-sword one. (A recipe for interesting yet unsuccessful paths). - Don't start something until you have set a finish line. You have full freedom on how you set the finish line. If the finish line is too far away, split into subproject for which you can set a closer finish line. Sometimes you will fail to reach the finish line for some unforeseen reasons, that's OK, just reevaluate if this impact the feasibility of the upper projects. - Don't start something you don't have the resources for. If some project are expected to be long-running, you should plan for the resources needed for their being interrupted. Because you can interrupt and restart projects, advancing is just picking some task for the day from your priority queue. This one is tricky because if you start to define a subproject that you have the resources to do (like building a prototype), once it is done, people will tell you it's just a prototype, and you don't have the resources to build the full thing nor find investors or customers). So maybe you shouldn't have built the prototype knowing you wouldn't be able to scale it up later. And then you get sunk-cost fallacy put on a dead-end road. - Don't share your projects. Uncouple task completion from external validation. External validation should be avoided. At anytime, you'll most likely be working on a subproject of a subproject. It's likely to be specific, boring, or some very valuable key brick that can be used for many other projects. If you chase the high of sharing a successful project and rely on it for taking each step, and at the end external success doesn't come, you are killing your future motivation source (in a kind of learned helplessness fashion). It often kills motivation, transforming the intrinsic reward of completing subprojects fully in your control into external rewards out of your control. Inversely it can lead you to delude yourself if you surround yourself with sycophants. External validation will want to set arbitrary finish lines upon you without regards for feasibility or resources needed. "Just turn it into money", "It's useless", "Don't give it for free" are things you don't like to hear when you run on an empty stomach after pouring your soul into making some great things.
