It's in our nature. If you are a plumber, there is an objective way to establish whether you put together a great piping system or not. Art is a bit more slippery than that. So, when you fill a gallery with dirt and someone comes along waving wads of bills, it's difficult not to take them because they become a tangible acknowledgement that what you've been doing actually makes sense.

Part of the blame can be put at the artists' door, too - no question. But I see our involvement more as a consequence. When there is too much money at stake, the whole system gets corrupted. Artists can be very vulnerable to these mechanisms.

I tend not to work with a specific person in mind. Art is a matter of statistics. It's not about individuals. It's about people.

I'm criticizing the way they are perceived. I was going through a book of Marina Abramovic and Ulay's 1970s performance work the other day. These people did two, even three Documentas or Venice Biennales over the course of a decade without any fuss. They would just treat it as any of their other engagements, with the same level of dignity and commitment they'd reserve for a one-day event in a small gallery on the Austrian mountains.

I don't design. I don't paint. I absolutely never touch my works.

I was a loser, most concerned with making a living. It took me 30 years to understand... I had to reinvent a system, find a way out, and set some rules that could work for me and a few others. I guess in the end that's what we all are trying to do.

My ideas are all the same but look different.
