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

I have always been aware that you have to get people listening before you can change their minds. Any artist's big fear is being ignored, so if you get debate, that's great.

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.

I realised that you couldn't use the tools of yesterday to communicate today's world. Basically, that was the big light that went on in my head.

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.

But the answer to how to live is to stop thinking about it. And just to live. But you're doing that anyway. However you intellectualise it, you still just live.

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.
