“The most important thing to realize is that the world doesn't care how you think it should work. The world has some problems, and you have to listen and learn to listen very carefully to hear other people explain what their problems are — hear other businesses explain what their problems are. If you solve those, they will reward you for it. But the world has its problems, and it doesn't care what you think in terms of how it should operate. That's what I'd tell myself.”
