I can't shout out, "Do this." I don't want to be prescriptive. I want to give you facts, and that's the way I've always operated, whether it's a historical fact or a scientific fact, and then you actually have to connect it in your brain.

I also wanted remembering the past relevant to the present. Some people wanted me to put the names in alphabetical order. I wanted them in chronological order so that a veteran could find his time within the panel. It's like a thread of life.

I always give the analogy of the Earth at Night picture, of 7.3 billion of us, right? And everyone says, "Well, that's population." Well, if you took the entire world's population and you lived at the density of Manhattan proper - not a bad place to live - how much space do 7.3 billion people take up? The state of Colorado. At which point I end my lectures, because I want you to be thinking ... is this really a question of population, or is this a question of land use and resource consumption? And let's face it, the top 1.3 billion of us are doing all the damage. Sorry.

You have to have conviction and completely question everything and anything you do. No matter how much you study, no matter how much you know, the side of your brain that has the smarts won't necessarily help you in making art.

You have to let the viewers come away with their own conclusions. If you dictate what they should think, you've lost it.

When I was very little, we would get letters from China, in Chinese, and they' be censored. We were a very insular little family.

I do not think you can find a reason for everything you make.
