Writers always think their greatest work is just ahead of them.

I'm not qualified for anything. I've had lots of little jobs, like picking grapes and being a tax man. I can't imagine not writing, because I've done it since I was five or six. Maybe I'd work in academia. That's always what the plan was.

I used to think that: whenever I heard that someone had taken 10 years to write a novel, I'd think it must be a big, serious book. Now I think, 'No - it took you one year to write, and nine years to sit around eating Kit Kats.'

I am, of course, a frustrated rock star - I'd much rather be a rock star than a writer. Or own a record shop. Still, it's not a bad life, is it? You just sit at a computer and make stuff up.

When I'm writing, I won't know whodunnit until maybe two thirds of the way through. Until then, I know as little as my detective. I just make it up as I go along. It's nerve-wracking, actually. You'll be half through and not know your conclusion. You worry one of these days the ending won't come. I'll be left with only two-thirds of a novel.

At all times, think like a writer, and keep those antennae twitching - that way, you pick up new ideas.
