I think there was something that made us not pay attention to climate change. Something that was up there. There was a saying when we were trying to pay attention to the environment that people used this phrase NIMBY - not in my back yard. People were saying, ‘I don’t care, it is not in my back yard.’ But now it’s in everyone’s back yard.

I have faith in the pendulum swinging. Right now it's so far against the wall that it can't go any farther; it's gonna start to swing back. That's my optimism. One of the cures is gonna be getting the American people to fully wake up. All the American people, particularly young people, because they're gonna inherit this earth; they're gonna inherit what we're doing.

If you want to slice into America, it's pretty red, white, and blue in terms of how it goes about things, but there's a gray area there, and I've always been interested in where things are complicated.

The way I deal with arthritis is to keep moving. As long as I can play hard tennis, as long as I can ski or ride a horse - all kinds of things can come your way. As long as you can, do it. People who retire die. My dad retired and died shortly after. Just keep moving.

I don't know what your childhood was like, but we didn't have much money. We'd go to a movie on a Saturday night, then on Wednesday night my parents would walk us over to the library. It was such a big deal, to go in and get my own book.

When I was a kid I was not a good student. I went to the University of Colarado, my grades were poor. I was asked to leave after a year. What I really wanted to do was to be an artist.

Golf has become so manicured, so perfect. The greens, the fairways. I don't like golf carts. I like walking. Some clubs won't let you in unless you have a caddy and a cart.
