“I asked a psychiatrist named Robin Skynner, with whom I wrote a couple of books, how many people in his profession he thought really knew what they were doing. He said about 10 percent. So for the next few years, every time I met somebody I thought was particularly sharp, I asked them the same question. The highest estimate I got was 20 percent. That explained so much. I spent so many years worrying about executives and critics, but once you realize that very few of them know what they’re talking about, everything is simplified.” –John Cleese
