The hardest thing in a novel is time. You've got [a line like] "two weeks later, he woke up with a headache," and you've got to add up that entire two weeks and what the date is and whether it works. That kind of stuff drives me crazy and if I don't have it exactly right, I can't move forward because I don't feel confident.

I always listen to music while I'm working and I always read aloud to my wife. I love to read aloud to an audience because there's a cadence and a beat. There's a music to the language that's very important to me.

I don't know who they are[my characters] . They're entirely invented characters. Maybe that's how I've been able to write so many books, because there are no boundaries for me. I can write a completely fantastical story like "Swept Away" or "Blinded by the Light" and then a non-comic drama like "Chicxulub" or something like "Birnam Wood" that has autobiographical underpinnings. Why not?

When you're in the midst of writing, it's a beautiful thing happening through you. Many people have said that it's not you, it's the soul of humankind and so on, I don't know. But it has the same effect [as music]. It takes you out of your body and out of this planet.

What I'm doing is exploring things. This is why I'm a fiction writer rather than an essayist or a politician or whatever. I just gather material and find a scenario, and see where it takes me. I don't have a plan.

Work ethic and this determination is all part of escaping the depressive side. Of course I'm manic depressive, maybe not to the degree that Exley was, but I think all writers are. There are highs and lows. Look at David Foster Wallace.

To be a friend of the earth, you have to be an enemy of man.
