Have more than one idea on the go at any one time. If it's a choice between writing a book and doing nothing I will always choose the latter. It's only if I have an idea for two books that I choose one rather than the other. I ­always have to feel that I'm bunking off from something.

What I'm really interested in, as a reader and as a writer, is the idea of the nonfiction book that is not defined by its content, by its "about"-ness. Where you read it irrespective of whether you're interested in the subject.

The process of book writing for me is entirely one of trial and error.

[William] Eggleston's photographs look like they were taken by a Martian who lost the ticket for his flight home and ended up working at a gun shop in a small town near Memphis. On the weekend he searches for the ticket - it must be somewhere - with a haphazard thoroughness that confounds established methods of investigation.

Like most writers I spend a lot of my time sort of thinking, "It's such agony, I can't do it."

Have regrets. They are fuel. On the page they flare into desire.

I'd have no rituals, but I'm a person of compulsive habit. That's just some awful residue of a ritual. And one of the reasons for that is my living this life, which is otherwise so free of obligations. It's not at all unusual for anybody who's independently employed to crave a way of living whereby they create the structures without which their lives would otherwise start slopping around all over the place.
