If you're a history buff, you know about J. Edgar Hoover. He was likely the most powerful man in the US. If you start reading about him, the books contradict each other constantly. I was often left with very little sense of the man personally. I had a sense of what he did and didn't do and what people disagreed about whether he did this or didn't do this or that, but I was like, "Why? Why was he doing all of this?" That was my big question.
Sometimes, I think there's a lack of ambition in me. But then sometimes, I think, no, you can, like William Blake said, you know, see heaven in a grain of sand. If you look really, really closely at a situation, you can find almost endless interest in it.
