I have walked many times around the world and each time it's different from the last one. It feels a little bit like I am a theatrical director, creating a theatre in space. It's really a theater in the sky. But of course the World Trade Center is certainly the most well-known of my productions.

Life should be lived on the edge of life. You have to exercise rebellion: to refuse to tape yourself to rules, to refuse your own success, to refuse to repeat yourself, to see every day, every year, every idea as a true challenge - and then you are going to live your life on a tightrope.

If I look at the performance of another friend Sting, whenever I hear him take over a stage and share his art with millions, it's very inspiring to me. So I have a lot in my life, a lot of friends who inspire me and I'm sure it goes the other way around, or so that I inspire them.

I don't like to risk my life, so I prepare sometimes for months or sometimes for years. But sometimes after a walk, I look what I have done, and I have a little bit of fear coming to me, just looking at pictures.

I am very attracted by the mysterious landscape of Easter Island. Not only because it is a piece of land that is further away from another, but also because of the beautiful statues of Moai that are there. To do a beautiful walk there, I would have to involve the Moai, and the Rapa Nui people who live on the island.

When you are a young person, the world is yours. You can do the impossible.

Limits exist only in the souls of those who do not dream.
