I really don't think it's being simply smart, because smart takes different paths. I can't see something without thinking of an analogy, it drives my wife crazy. It goes back to Prince Valiant. If I sit down in an elevator that's stuck, God forbid, all I want is a book of history. I don't want a political science text, I want a historical reference.
Some people are incredibly bright and they're dull.
Some people, while being dull, are rigorous, systematic, they're Sancho Panza. And I like Don Quixote a little more. I've always thought it's the nicest thing anybody ever said about me, and I think it comes down a lot to just the temperament you have. I don't think you learn it. I simply don't think it's available in a formal pedagogical way.
