If you study a great work of art, you'll probably find the artist was a kind of genius. And geniuses are different to you and me. So let's have no talk of temperamental, self-absorbed and petulant babies. Being a good artist is the toughest job you could pick, and you have to be a little nuts to take it on. I love them all.

If you can't take a good kicking, you shouldn't parade how much luckier you are than other people.

I primarily buy art to show it off.

Lots of ambitious work by young artists ends up in a dumpster after its warehouse debut. So an unknown artist's big glass vitrine holding a rotting cow's head covered by maggots and swarms of buzzing flies may be pretty unsellable. Until the artist becomes a star. Then he can sell anything he touches .

My aim in life isn't so much the pursuit of happiness as the happiness of pursuit.

The most abiding memory of visiting Lucian Freud's studio were his eyes, with the gimlet gaze of a Hooded Falcon. But he made for very relaxing company, quick to be amused at the world and his own peccadilloes. He enjoyed the seedy squalor of his rooms in a posh house in the most desirable part of Holland Park, and living up to his persona as an oddball bohemian.

I liked working in advertising, but don't believe my taste in art, such as it is, was entirely formed by TV commercials. And I don't feel especially conflicted enjoying a Mantegna one day, a Carl Andre the next day and a brash student work the next.
