I don't have any interest in changing a system, because the system will simply get bucked back by people who haven't changed.

We're a young species; We're only 175,000 years old. On the evolutionary scale, life on this planet is 4 billion years old. We're 175,000 years old. So we're trying something out. Who wouldn't think it would be better to have the most stuff to take as much as you could? As we do that, we see why the moral prophets come along and say, don't even store into barns, right? It's easier for a camel to pass through the eye of the needle than a rich man to enter the kingdom of heaven. We've seen we plunder nature. We plunder our neighbor. We create enemies because we're against each other.

The word contentment comes from the word content, which is what we hold inside - love, value, a feeling of a life that has meaning or purpose, a cause greater than yourself that you're a part of. These are the things that bring true happiness. As a culture, I think we need to redefine what it means to be happy.

I am operating under the philosophy that I will simply use what I need and the rest - even if I still have it somewhere - is not mine. It is others'. It is for the healing of the natural world. And it is in the process of returning.

I have not walked away from Hollywood. I'm walking away from the way I personally did business in Hollywood. The budget of whatever movie I do needs to be efficient; it needs to consider what kind of resources we're using and how to be as responsible as possible.

Death is not the enemy. A life lived without love is the enemy.

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.
