When photographers get beyond copying the achievements of others, or just repeating their own accidental first successes, they learn that they do not know where in the world they will find pictures. Nobody does. Each photograph that works is a revelation to its supposed creator.

For a lot of people, well-meaning teaching has made poetry seem arcane, difficult, a kind of brown-knotting medicine that might be good for you but doesn't taste so good. So I tried to make a collection of poetry that would be fun. And that would bring out poetry as an art, rather than the challenge to say smart things.

'Write' is almost the wrong verb for what I do. I think 'compose' is more accurate because you're trying to make the sounds in your mind and in your voice. So I compose while I'm driving or in the shower.

In many ways, my entire graphic novel career was a long diversion. Originally, all I wanted to do was to be an underground cartoonist and maybe bring out a groovy underground mag.

I met, not long ago, a young man who aspired to become a novelist. Knowing that I was in the profession, he asked me to tell him how he should set to work to realize his ambition. I did my best to explain. 'The first thing,' I said, 'is to buy quite a lot of paper, a bottle of ink, and a pen. After that you merely have to write.'

Writing is a deep-sea dive. You need hours just to get into it: down, down, down. If you're called back to the surface every couple of minutes by an email, you can't ever get back down. I have a great friend who became a Twitterer and he says he hasn't written anything for a year.
