I went to an auction in the late '70s and bought a small Renoir. People said, "Why did you buy a Renoir that size?" I said, "I can put it in the safe with my diamonds." And that was a true story. I bought it to put it in the safe.

Art is like an avalanche being poured down your throat. You know it's going to crack, eventually it's going to go out of fashion. I wish there was much less happening. I wish there were fewer art dealers. I wish there were fewer auctions. I wish there were just two auctions a year.

I went to a job and sat down as a proper apprentice, learning how to make jewelry. It involved a lot of remodeling and repairing. It was a bad time in England in those days and people didn't have much money - they would repair a ring rather than buy a new one. They would thicken up the gold. I learned all the ways to make something look new again.

Don't try to buy art as an investment. Buy something you really love because you're going to have to look at it again tomorrow. And an investment can go up or down. Buy something you really adore, you really like, and you want to live with. And if you decide some years later you don't want to live with it anymore, sell it. Get out.

I wish there were fewer art dealers. I wish there were fewer auctions. I wish there were just two auctions a year. It's just too much. And at the end of the day, if you're a dealer and a professional, fine, that's your business, that's all you do. But as an individual, if you're not a dealer and it's not your business, you need time for these things. You need time to study what's happening. You need time to understand the market. You need time to go to a museum. You need time to see a show. You can't go to one every day. It's becoming a trend.

One of the great things about collecting contemporary art is that you mix with contemporary people.
