The Doors are perfect paintings; a relief from the picture world I’ve created for myself.

I'm more and more fascinated in my own work. I work from 10 A.M. until about 9 P.M., but it's not an obsession, it's a pleasure. There's never enough time.

Small paintings can be fantastic. But you can't often get a narrative out of a small painting. In any case, museums are huge places, and you want to take up some space.

People constantly describe me as a formalist or even a minimalist, but I'm not really bothered with the rules of painting or the history of painting. My approach is that everything is mine. I take what I can use from wherever, and then I forget where I've taken it from. But there is no point me making anything that looks like anyone else's.

Sometimes I can see the whole painting from the outset in my mind's eye. But more often than not, that idea doesn't last the duration of the painting. Sometimes it comes out easy, just as I had envisaged. But that is reasonably rare.

One drawing demands to become a painting, so I start to work on that, and then the painting might demand something else. Then the painting might say, 'I want a companion, and the companion should be like this,' so I have to find that, either by drawing it myself or locating the image.

It's not part of my ambition to become fabulously rich. My plan was always to make my pictures, and hopefully people would buy them, and then I'd buy a studio, buy a house, help friends out, do bits and bobs - but I've no idea after that.

I'm probably not going to develop to a final state as an artist. Like, become better and better, more and more refined. Become 'pure.' I don't think that's going to happen to me, because I don't really see that as something I want to explore.

I'd like to give people leaden boots in galleries, so they'd be a bit slower in front of my paintings. And that's because I spend so much time looking at them. I can look at them a long, long time without getting bored. I disappear.

I lived on nothing for years - squatted where I lived and where I worked, stole electricity, made things from stuff I found in skips, used paper that had been discarded - you do everything you can do to keep going and not have to get a job.
