I didn't care what, how much adversity life threw at me. I intended to get to the top.

We're too many people; that's why we have global warming...on a voluntary basis, everybody in the world's got to pledge to themselves that one child is it.

I like snakes. I like hummingbirds. There's nothing on earth I don't like. Frogs. Salamanders. The bunnies, the giraffes, the hippopotamuses.
