“Every time I think I’m getting smarter I realize that I’ve just done something stupid. Dad says there are three kinds of people in the world: those who don’t know, and don’t know they don’t know; those who don’t know and do know they don’t know; and those who know and know how much they still don’t know. Heavy stuff, I know. I think I’ve finally graduated from the don’t-knows that don’t know to the don’t-knows that do.”
