I created a successful outdoor youth festival - the Liverd festival - against all good advice. It was a great way to explore and investigate social sculptures. Having that as my kind of studio, outside of a museum or precious white-cube gallery, that was a kind of education.

How much we owe to good teachers, good education, and good advice!

I watch children a great deal; their idea is that rules are always negotiable, whereas you absolutely cannot joke at the airport about your toothpaste, and you cannot rollerblade in Grand Central Station. I keep running up against these things.

Formally, I did my studies in the sciences, but I was very conscious that I was being deprived of culture. While studying neuroscience, I was running a rock-music festival and was able to use that as a platform to explore what it takes to produce art for 20,000 inebriated 20-somethings.

Just listen to your heart, it'll never lie to you.

Unfortunately, celebrity is a powerful thing. It can influence people, but if it can influence people in a good way, then that's a great thing.
