I love Frank Capra. He believed in the goodness of people and one man's ability to fight and often triumph.

We started by asking what’s wrong with the world, and we ended up discovering what’s right with it.

Nature actually works through intense cooperation. There is competition in nature , but it thrives through cooperation. We don't teach this to our kids. It's actually a violent ideology. It's why kids go into school and bully each other and god forbid do things even worse. Cooperation will become the marching orders of the human species or we're not going to make it.

The one thing that advances a society is not technology or so-called development; its love - that one principle.

I wasn't big in the party scene but I did have an excessive lifestyle. I had much more than I needed. I think that was a manifestation of a certain kind of mental illness.

Nature is very clear on this. In fact, there's one fundamental law that all of nature obeys that mankind breaks everyday. Now this is a law that's evolved over billions of years and the law is this: nothing in nature takes more than it needs. A redwood tree doesn't take all of the soil's nutrients, just what it needs to grow. A lion doesn't kill every gazelle, just one. We have a term for something in the body when it takes more than its share. We call it cancer.

I didn't want to hear the usual answers about what's wrong because I believe these are symptoms: global warming, genocide, hunger, poverty, war, environmental crisis. If we can identify the root cause, we can change our ways.
