I try not to be too precious about my writing, and I try to be willing to walk away from it for a few hours when something's not working, to let things percolate a bit. I try not to hide myself away from life too much, because I think that's a risky thing for a writer to do.

We always planned to move back to the Republic but it never happened, I'm not sure why. My dad is one of those immigrants who never leaves the place he came from. He talks about Ireland all the time. If any Irishman wins at any sort of sport, he sees it as a personal achievement.

You learn so much with each book, but it's what you teach yourself by writing your own books and by reading good books written by other people - that's the key. You don't want to worry too much about other people's responses to your work, not during the writing and not after. You just need to read and write, and keep going.
