A painting probably is the most shocking increase in value, from what it costs to make to what you sell it for.

But whenever I look at the question of how to live, the answer's always staring me in the face. I'm already doing it.

It's amazing what you can do with an E in A-Level art, a twisted imagination and a chainsaw.

A lot of people thought I wasn't doing anything because I was spending a lot of time socialising and going out, but I've always managed to get work actually done.

But I'm more interested in why people are frightened by Jaws and why Jaws was such a hit than saying Spielberg's my main influence.

In fact, the first piece of art I ever sold, I paid someone else to make the next one, so I could actually keep going out drinking.

I think I've always been afraid of painting, really. Right from the beginning. All my paintings are about painting without a painter. Like a kind of mechanical form of painting. Like finding some imaginary computer painter, or a robot who paints.
