You become a writer because you like to be alone in a room with your books.

Publishing a book is a great thing, and I'm grateful, but it's also a horrible, exposing thing. Once you've published a book, you never write quite as freely again. You're aware, from that point onward, of the kinds of things critics might say about it. You're aware of the kinds of things your publishers might like and dislike about it. You're half-aware of marketing strategies - of all the stuff around the book. Whereas with your very first piece of fiction, if you're lucky, those things barely occur to you at all.

Writing fiction, for me, is a more indirect form of self-exploration than writing verse. When I'm working on a novel I'm moving characters around and I'm thinking about plot and there's a lot of other things going on at the level of structure and story. With a poem, a single idea or line or emotion can sometimes be enough - there's often a sense, in the best poems, of capturing a single instant. Perhaps poems differ from prose in the degree of solace they can offer - by speaking so personally, so directly, about shared experience. A few lines of poetry can provide comfort.

Most of the poems I write go through forty versions and then stay in a file on my computer. I'm not very good at sending stuff out or feeling that something is ready to send out and I never have been. Part of the problem is that as soon as a poem is finished, it stops being all that interesting to me.

New York is great for writers insofar as you can pay someone to bring you food, to take your washing out and bring it back clean. It enables you. Writers always feel guilty when they're doing anything but writing, and New York allows you to really write all the time if you want to - though my kids put a limit on it.

I think New York is working its way into my poems. It takes a while for a place to filter its way onto the page, but I've been reading more and more American poetry and I certainly feel it as quite a freeing force. Coming from the formally ordered tradition of poetry in Ireland, I find the expansiveness of American literature freeing in some sense.

I think all writing is about writing. All writing is a way of going out and exploring the world, of examining the way we live, and therefore any words you put down on the page about life will, at some level, also be words about words. It's still amazing, though, how many poems can be read as being analogous to the act of writing a poem. "Go to hell, go into detail, go for the throat" is certainly about writing, but it's also hopefully about a way of living.
