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

When it comes to the British monarchy, I prefer to be seduced by an image than presented with a real person. It's kind of a Warhol thing.

Most people live in the city and go to the country at the weekend, and that's posh and aristocratic, but actually to live in the country and come to London when you can't take it any more is different.

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.

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.

I just wanted to find out where the boundaries were. So far I've found there aren't any. I just wanted to be stopped, and no one will stop me.

I can't understand why most people believe in medicine and don't believe in art, without questioning either.
