I'm a millionaire, I guess, but I'm just a normal person and I like everybody, taxi drivers, whoever you are, to call me by my first name and talk to me on a man-to-man basis. I think the garbage collector is as important as the goddamned president.

If I had to predict, the way things are going, I'd say the chances are about 50-50 that humanity will be extinct or nearly extinct within 50 years. Weapons of mass destruction, disease, I mean this global warming is scaring the living daylights out of me.

The U.N. had such lofty goals to eliminate poverty and stop war and cure diseases and help refugees - things that no one country could do.

We'll be eight degrees hotter in ten -- not ten, but thirty or forty years, and basically none of the crops will grow. Most of the people will have died and the rest of us will be cannibals.

I didn't get here for my acting... but I love show business.

To succeed you have to be innovative.

I don't measure success in numbers, but I consider my contributions of more than $1.3 billion to various causes over the years to be one of my proudest accomplishments and the best investment I've ever made. Those dollars have improved lives, saved species, fought disease, educated children, inspired change, challenged ideas and opened minds; at the time of my death, virtually all of my wealth will have gone to charity.
