" When a new company is formed, its founders must have a startup mentality—a beginner’s mind, open to everything because, well, what do they have to lose? (This is often something they later look back upon wistfully.) But when that company becomes successful, its leaders often cast off that startup mentality because, they tell themselves, they have figured out what to do. They don’t want to be beginners anymore. That may be human nature, but I believe it is a part of our nature that should be resisted. By resisting the beginner’s mind, you make yourself more prone to repeat yourself than to create something new. The attempt to avoid failure, in other words, makes failure more likely. "
