I'm 43. I'm not ready to sit down in a chair with my name on it yet.

When I used to do abstract paintings at school, like everyone else, the tutor said these would make great curtains. I would always neglect the formal stuff that was going on by using colour, because colour kind of came naturally to me.

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.

I did a butterfly show in Berlin, and we had a guy who's an expert on butterflies; who bred them all and who looks after them all in the space.

Making art, good art, is always a struggle. It can make you happy when you pull it off. There's no better feeling. It's beauteous. But it's always about hard work and inspiration and sweat and good ideas.

I quite like it to be risky. I'm not ready to sit down in a chair with my name on it yet. I've arrived at that point in the art world where there really is a chair that you sit in.

I always feel like the art's there and I just see it, so it's not really a lot of work.
