Climate change is critical to me because I'm a parent; I feel a sense of responsibility to the future. I'm not going to be around to see its worst effects, which are going to be hitting in the 2030s, '40s, '50s, but my kids will.

Pick up a camera. Shoot something. No matter how small, no matter how cheesy, no matter whether your friends and your sister star in it. Put your name on it as director. Now you're a director. Everything after that you're just negotiating your budget and your fee.

Here's my philosophy in life: If there's a fire, you put it out. If there's a flood, you fill sandbags and you build a dike. You roll up your sleeves and you get to work.

You can have a strong economy or you can help the environment, but you can't do both at the same time. That's ridiculous. In fact, as a sustainable vision for a healthy economy has to involve changing our energy policy and changing with respect to the natural world. Because we're hitting nature's thresholds, we're hitting nature's limits with respect to water and crop yields and energy use and fossil fuels heating the atmosphere at the same time we're past global peak and running out of that.

What are the lessons learned? Well, I think number one is curiosity. It's the most powerful thing you own. Imagination is a force that can actually manifest a reality. And the respect of your team is more important than all the laurels in the world.

A director's job is to make something happen and it doesn't happen by itself. So you wheedle, you cajole, you flatter people, you tell them what needs to be done. And if you don't bring a passion and an intensity to it, you shouldn't be doing it.

I've sworn off agnosticism, which I now call cowardly atheism. I've come to the position that in the complete absence of any supporting data whatsover for the persistence of the individual in some spiritual form, it is necessary to operate under the provisional conclusion that there is no afterlife and then be ready to amend that if I find out otherwise.
