I used to believe I was going to live forever. And then you suddenly become aware that you're not.

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.

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

For me, art is always a kind of theater.

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 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 always feel a bit trapped when a painting goes for millions of pounds and only one person can have it. If you can have that as well as a poster on every student's wall, then you're in a very enviable position. I'd like to do a Damien Hirst for £500 at some point.
