The tough thing about adulthood is it starts before you even know it starts.

In 1973, I was shown a graphic of how dependent the United States was on nonrenewable resources like oil and coal and that little was being done to change that. It seemed irrefutable that we needed a change in direction or we'd be paying a huge price down the road. That's when I made a commitment to become a political activist.

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.

'Butch Cassidy' was the only film I ever enjoyed making.

I can't think of anything outside of having the gift yourself and creating yourself. I can't think of the next better thing to do than being able to put it back. Creative expression, I think, is vital to the success of any society.... A society without art will die.

I have no regrets, because I've done everything I could to the best of my ability.

I don't think you can ever return, really.
