When people start thinking of you more as a persona, they are less inclined to allow you to move into different areas. Sometimes they're wrong. Sometimes they're just very stereotypical or restricted in their own thinking of what they'll allow you to do.

I try to avoid giving advice. The only advice I will give is to pay attention. I don't mean to the screen in your hand. I'm talking about the natural world. I spent a lot of time educating my children about nature by putting them in nature. I said, "I want you to listen; I want you to look." There's so much technology coming into our lives that takes us away from the natural stuff, so I'm pushing the other way.

What we are living with is the result of human choices and it can be changed by making better, wiser choices.

San Franciscans are very proud of their city, and they should be. It’s the most beautiful place in the world.

It's a creative enterprise, just like art, just like painting, music. Creating something can be done in different categories, so to do it in film is just another expression, which is great. Because it translates so well because so many people see the work, if you're lucky.

Ideas aren't real estate, they grow collectively and that knocks out the egotistical loneliness that generally infects art.
