“Socrates didn’t know much. There wasn’t much he held for certain. But he was sure, he said, that ‘we cannot remain as we are.’ It doesn’t matter who you are. It doesn’t matter what you’ve done. Nobody is as good as they could be. Nobody is perfect. Everybody can improve. There are few self-fulfilling prophecies more important or more dangerous than this. If you think you have room to grow, you do and you will. If you think you’re as good as you can be… you’re right. You won’t get any better.”
