“The things I worry about the most is that I’m completely uneducated. You couldn’t even really give me credit with a high-school education. That troubles me a lot. If we had to discuss trigonometry I would have to go and actually do homework before I could talk about it. I also just don’t have a solid liberal education. People who are very well-educated always tell me that education means nothing. But that’s because they have it. I also know, because I keep a very elaborate journal, that I am unreliable in terms of what I’m talking about. These are all things which come down to my worrying about not knowing what I’m talking about, and that’s the worst kind of bullshit. Also, like anyone who’s had success, I tend to give lip service to luck.”
