The way you would know if someone is famous in the art world is that you would ask your mother. My mother knows who Picasso was. She knows who Warhol was.

I never had a penny to my name, so I changed my name.

If you're an artist or someone creative, it's all about cheap rent and not having to work for a living. That's what it's always been about. Unless you're a trust-funder or you somehow score a great part-time job or you work for another artist, you're going to go where you can afford to live.

The problem with art is, it's not like the game of golf where you put the ball in the hole. There's no umpire; there's no judge. There are no rules. It's one of its problems. But it's also one of the great things about art. It becomes a question of what lasts.

The subject comes first, the medium second.

A lot of it's experimental, spontaneous. It's about knocking about in the studio and bumping into things.

It's interesting how people who were once fairly radical can become, later in life, kind of conservative and not just in terms of politics - how if you're an artist, you can start out being somewhat avant-garde and then end up doing landscapes. Sometimes the opposite can happen, but it's usually the other way around.
