I have great respect for Sean Penn. It's like most relationships that fail. It's not one thing, it's many thing that go on over a period of time.

I go to Malawi twice a year. It's where two of my children were adopted from, and I have a lot of projects there that I go and check up on and children who I look after. It's sort of a commitment that I've made to this country and the hundreds of thousands of children there who have been orphaned by AIDS.

I cheat on my books a lot, which is not a good thing because it's good to stick with one book and get to the end of it, but I'm a book philanderer.

A lot of places I go are dangerous, like Tel Aviv or Rio, but that never stops me from going there and putting on a show. I have good security. I don't worry about that.

I like pushing the envelope. But I don't like to do it just for the sake of doing it.

Economic markets are collapsing. People all over the world are suffering and people afraid. What happens when peep are afraid? They become intolerant.

I like to be provocative. I like to make people think. I like to touch people's hearts. And if I can do all three of those things in one fell swoop, then I feel like I've really accomplished something.
