I had a very insightful friend who warned me back when I stopped reading scripts, 'It's easier to change directions while you're still moving.' If you stop, it's harder to get started again. I still don't think I made the wrong decision, but he was right.

Styles, like everything else, change. Style doesn't.

We have no reason to think that climate change is harmful if you look at the world as a whole. Most places, in fact, are better off being warmer than being colder. And historically, the really bad times for the environment and for people have been the cold periods rather than the warm periods.

It's better to get smart than to get mad. I try not to get so insulted that I will not take advantage of an opportunity to persuade people to change their minds.

If you don't like the way the world is, you change it. You have an obligation to change it. You just do it one step at a time.
