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.

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 love color. I feel it inside me. It gives me a buzz.

For me, art is always a kind of theater.

I always try to make everyone mellow down, make sure everybody's happy. The people I have employed have always kind of stayed with us. A lot of people who come to work for you are artists in their own right. And they want to work for you because they want to pick something up.

You've got to be oblivious to other people, the push and pull of other people's opinions, the way other people measure success. It's then that you realize you are 100 percent who you are and you have to use that who-you-are 100 percent in order to create great things.

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.
