By sixteen I thought, "Ah, this is all crap, you're all sheep, I'm not going to church, leave me alone." And then at a certain point in my teens I started to go to Catholic churches, by myself. Not because I wanted to be Catholic, but because I wanted to light a candle and say something like a prayer and just sit there. There was something I was missing or trying to reconnect with. But it was a secret at the time. I'd developed this cynical persona and the last thing I wanted to admit was that I was skulking around churches in my spare time.

I started writing the book without realizing I was writing a book. That sounds stupid, but it's true. I'd been trying and failing to make a different manuscript work, and I thought I was just taking a break by writing some short stories. I'm not a very good short story writer - the amazing compression that is required for short stories doesn't come easily to me. But anyway, I thought I'd try to write some short stories. And a structure took shape - I stumbled upon it.

There is still an assumption among many people that to be black is to be lower class. In the last fifteen to twenty years, perhaps even further back than that, there's also been an explosion of a very wealthy black class in the United States, but those people are often treated as special cases: they're athletes, entertainers. Jay-Z. Basketball players. The country metabolizes the fact these rich black people exist, but it seems only to reinforce the idea that every other black person is limping along in poverty.

The critics and the reviewers are more frightening than anything else!

I think of my success as a kind of fluke. How else could I possibly think of it? And although it's a banal thing to say, I wrote my book because I was writing my book. At first I didn't know I was writing it, and one of the amazing things that happened as I was putting sentences down on paper is that some of the things that are most sacred and important to me rose to the surface of the prose.

A belief in God may not be fully within me anymore, but there's still a belief in belief. The high drama and power of the Church has stayed with me. As a child in church, I saw grown men at the altar crying out for God's mercy. And the idea of someone doing that has become a joke in the popular culture, but when you are there and you see it, you experience - for a moment - an incredibly raw, honest, strange insight into what it means to be a human being. Those experiences don't leave you. Whatever you think of them, they are powerful experiences.

I think that people have some sort of vision that everybody is moving towards perfection, and that there is some sort of set steps or something like that that you can move through to get to that place, and that that's sort of the project of being alive.
