When you're in the public eye - whether it be entertainment, sports, medicine, politics, whatever way - you have an opportunity, and I think also an obligation and a responsibility, to disseminate good information.

I bought my first electric car in 1970. Its top speed was 15 mph and it had just a 15 mile range - it was essentially a golf cart with a windshield wiper and a horn.

We, who have so much, must do more to help those in need. And most of all, we must live simply, so that others may simply live.

People don't want to change. It's hard for people to change and it's hard for businesses to change. If I was running an oil company, I would be resistant to change too.

One of the regular intervals of meditation in my life, believe it or not, is in my car.

We run around so much - with the best intentions: I want to save the rain forest. I've gotta clean up the oceans. I've gotta save the dolphins. All worthy efforts, but if you're not centered and you don't have the serenity in your life you need to accomplish that task, you're not going to do a very good job.

To be a modern person in 2012, you are often required to have some electronics in your life. And I do. I try to put that phone down, put the computer away, and get out there and hike in the woods; feel it in my feet, feel it in my hands; get out in the garden and feel the soil under my fingers, my fingertips and my fingernails. I try to be involved in nature in a very tactile way. I think that's important.
