As a father, I would say I am more like a mother. I do a lot of hugging.

Painting is so poetic, while sculpture is more logical and scientific and makes you worry about gravity.

For me, art is always a kind of theater. When I started the spot paintings I made them as an endless series. But I was never serious about it being an endless series. It was just an implied endless series. The theater means you just have to make it look good for that moment in the spotlight.

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.

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