I think that the project of being alive is to be alive. So there will always be twists and turns and steps forward and steps back, but that's just your life. There is no sort of place at which to arrive, and I think that the more one focuses on an end point, the harder it is to get there. It's like the horizon, sort of ever receding, ever receding, ever receding.

Certainly I had from an early age a sense of the power and beauty of religious texts - the awesome magnitude of the Bible stories I was reading as a child. The hymns. The sermons. I can still vividly hear the sermons and the pieces of soft piano music played after them, the preacher asking if anyone wanted to come up to the altar and accept Christ as their savior.

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.

If there had never been the Great Migration there would never have been jazz, there would never have been Michelle Obama. A lot of amazing black people exist in this country because of the Great Migration. That's nation-building.

One thing I am learning is to slow down. Multitasking is great, but I when try to do everything at warp speed I just end up with typos and stress.

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've been writing all my life. Even though I didn't have sort of careerist aspirations as a writer, it was very much my identity.
