I think I can work anywhere, but you don't get the same kind of inspiration everywhere. New York theater has become a big inspiration for me. I only started writing for the stage myself because I like to see the good, mostly off-Broadway plays in New York.

When I write a book I'm always questioning the project as a whole. I always feel I might have to just throw it away and forget about it, and I've done that with novels I've started and worked on for a long time. It's an option I need in order to write freely.

You say fate is almost indispensable to literature - I think it's completely indispensable, at least in a novel, because a novel always has a plot. Even if nothing happens, even if someone just spends a day walking around Dublin, or whatever, there's still something going on.

For a while I never show anybody what I'm writing, and during that time I need the feeling that publishing is only an option. I might publish this, I might not. I think if I had to publish it, I might panic.

Also, whenever you have direct speech, and I don't quite know why, but it always gets better in English. Dialogue, the flow of dialogue, English just has a better way with it.

I think that's just what happens when you write a big bestseller. After that you need to find out: What's the best way to go on? And the worst thing you could do would be to try to repeat the formula. That would be suffocating.

I really just wanted to write about three brothers. When you do that, though, it gives you this wonderful opportunity to tie together different social milieus, because siblings usually move into different worlds as they grow up.
