L.A. is very special to me, so far away from my world on the East Coast, Europe, Asia. It's a bit of an island for me - less intense, less busy; because of time difference and location, it has a calming effect. At least it used to be all that.

At the end, the key thing is you've got to live with yourself. That's the real test. Everything else is fleeting.

Commodity exchanges have a lot of advantages. One, you are helping transparency. Two, they are not political. It's institutional building. It can survive any environment, in theory.

I felt I was owned by possessions.

Other people might have family - three kids or five houses. In my case, that doesn't exist. I'm going to give everything away. Everything has been transferred to charitable trusts. There is no question about that. The question is where, not if.

I don't have a house, and I don't have a lot of time for socializing, so every year I have a party for all of my friends.

If you erased New York, I hate to say it, if you erased Frankfurt, even London, the world would not have changed.
