Teenagers are always sneaking around in drawers where they shouldn't go and reading things they shouldn't be reading. And that's an attempt to try, I think, to penetrate, that's how I found out as a teenager what was going on, was by sneaking into drawers and reading letters that I had no business reading.

I do keep up at night. I try not to let my mind go to extremes in the middle of the night because it would be better to turn all that stuff into dreams; it would be better if I was sleeping, because dreams become good metaphors for what's really going on inside of you.

I'm a reader. I like - I'm a great reader. I keep going back, though, to certain authors, just like I love film, but I keep going back to just five or six certain filmmakers. In literature I like Chekhov, for example; I think he's my favorite. And Flaubert - you know, that kind of concision. But I also like Tolstoy; I love those romances that, you know, weigh 500 pounds and take months and months and months to read.

My interest really is psychology, what's going on in people's minds as revealed on their faces and in their posture. That is my strength. And it's something that came from probably being a silent observer for most of my life and having to read what was going on in people's minds from only their postures or from their expressions.

I found great value in teaching students from the outset of their studies how to draw very realistically. Otherwise, you're starting deep into the alphabet instead of having started at the start. If you discard essential things like drawing, design, color and so on at the beginning, then you're just sort of floating out in space, without any basis to work from.

Leaders of the world, my message to you is simple: to achieve universal peace and understanding on this planet you have only to speak plainly, even though you may look foolish. This is a thousand times better than looking good and talking nonsense.

One of the glories of doing the book So You Want to Be President? was the shifts in tone, where I was able to be humorous and then very serious. And the impeachment page is certainly the best example of that. I didn't have to think too much about how to present this one. I got the idea right away that a good way of showing the shame of President Nixon would be to put him down in the shadows under the Lincoln Monument, with Lincoln sort of glaring down at him from an elevated, better-lit position.
