"The wise say that there are three kinds of people in the world. There are people who never learn anything one way or another; there are people who learn from their own mistakes, eventually and with great pain; and then there are the really wise people who learn from other's mistakes and spare themselves the suffering. And I’m definitely in that middle category. I’m an empiricist. IA lot of stuff I have to fail at spectacularly, in person, in order to understand it."
