This is something that I'm continually trying to come to terms with. The intelligence distribution is tighter on the high end than most people realize. By that I mean, the smartest people aren't really amazingly smart. This reply, from Clay Christensen (Business School Prof at Harvard, Rhodes Scholar...must be bright!) when asked how it felt to be the top of his field, in this case material sciences, has always stuck with me:
"You know, there's real disappointment. When I was younger, I looked up at the top of the mountain and thought, Wow, those guys are really smart! When you're near the top of the mountain looking down, you think, Boy, if nobody is smarter than I am, the world is really hurting!"
It's all perspective.
