A lot of Silicon Valley types are perfectionists. They always worry that their solutions are imperfect. That’s when I advise them to follow the “Angry Bear Principle”:

You don’t have to outrun the angry bear–you just have to run faster than the other people the bear is chasing.

Whenever people dwell on their imperfections and despair, I remind them, you don’t have to outrun the bear, just the competition.
