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 can't draw. I can't paint. But what I can do is tell somebody else what to do. I'm a creator. I can tell an artist what to do. I can be behind the artist. I have the eye, so I can move things around. I can put stones together. I can match them.

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

When there's an opportunity, some people pass it by. I've been lucky enough to recognise opportunities and every day, in my business, there's an opportunity somewhere - to buy, expand, design.

Unfortunately, some of the young talants are becoming fashionable. And anything that's fashionable can become unfashionable. So one has to watch that. And it's very easy today because there are so many events - art fairs, gallery openings, etcetera. In fact, that's another thing that concerns me, the quantity of gallery openings. In my office in London, I get back after a week, and I have 30 invitations. It's too much.

I think a lot of people are involved in art because of the fashion of art and the conversation. It gives them a certain sophistication, something to speak about. But art is, if it's conceptual, really about understanding the concept. And if it's beautiful, it's about seeing the beauty. It's gone much further than that now. There's too much commercialism attached to art. If the market cracks one day big-time, you'll frighten so many people away who will never come back. Because they don't really feel for art. People who buy art should want it because they love it, they want to enjoy it.

You learn about yourself when you're collecting art. You learn what you're capable of. After all, we're not speaking about pennies-we're speaking about vast sums of money. I do it on my own back without advice, so I've got the confidence to do it.
