In my teens I was interested in photography. Then I decided that I should learn something about the world of commerce. And I came to America at age 17 to escape Europe. I went to NYU - nothing better than being 17 years old and coming to New York.

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.

Luckily the whole world is not like me, or else, there would be no world.
