Art is the closest you can get to immortality, though it's a poor substitute - you're working for people not yet born - and people want it because it is brilliant. It ends up in museums anyway; the rich have to give it back to the people, it's their only option. There are no pockets in a shroud.

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.

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

I think money is important for everyone, because the lack of it is so painful.

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

But I think it's more that when you're young, you're invincible, you're immortal - or at least you think you are. The possibilities are limitless, you're inventing the future. Then you get older and suddenly you have a history. It's fixed. You can't change anything. I find that a bit disturbing, to be honest.

You've really got to get down on the floor with yourself and get low in order to make great art. I think you've just got to accept who you are and do the most unbelievable things.
