I don't know how to make people who absolutely have to be obsessed with paying a week's energy bills... obsessed with climate change... It's very hard.

Climate change is the single biggest thing that humans have ever done on this planet. The one thing that needs to be bigger is our movement to stop it.

The technology we need most badly is the technology of community, the knowledge about how to cooperate to get things done.

The holes in my shoes and the holes in my jeans make me whole!

I've got all my life to live and I've got all my love to give

I feel like I haven't started yet. I'm looking forward to the ninth album, the thirtieth movie.

The Olympics are a wonderful metaphor for world cooperation, the kind of international competition that's wholesome and healthy, an interplay between countries that represents the best in all of us.

Marcia was incredibly organized, obsessively neat ... I mean she folded her underwear like origami.

I don''t wanna be rich, just live good.

There never was a man on earth who pitched as much as me. But the more I pitched, the stronger my arm would get.

I am nothing without the players.

To learn, you have to listen. To improve, you have to try.
