"Thinking with me is like looking for a person whose address I don't know. I stand on a street corner all day long waiting for him to pass by. Certainly there are more efficient ways of locating a person whose address you don't know. But if you have a whole lifetime to wait and enjoy watching things go by, then waiting on street corners is as good a method as any. If you don't find the person you are looking for, you might meet someone else."
