I've never learned to drive because I get lots of ideas when I'm a passenger in a car. I love to get in a car with a driver and just think and work things out.

As soon as something becomes art I think you get over the fear

Great art - or good art - is when you look at it, experience it and it stays in your mind. I don't think conceptual art and traditional art are all that different.

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.

Artists are like everybody else.

I was brought up Catholic, and I felt the power of art from a very young age - seeing the brutality of all those images of flayed apostles and tortured saints was a pretty strong introduction.

In an artwork you're always looking for artistic decisions, so an ashtray is perfect. An ashtray has got life and death.
