In my experience, the way you end up doing good in the world has very little to do with how good your initial plan was. Most of your outcome will depend on luck, timing, and your ability to actually get out of your own way and start somewhere. The way to end up with a good plan is not to start with a good plan, it’s to start with some plan, and then slam that plan against reality until reality hands you a better plan.
It’s important to possess a minimal level of ability to update in the face of evidence, and to actually change your mind. But by far the most important thing is to just dive in.
Great comment. I also like Nate Soares’ Dive in:
