I never stop thinking about what I have to do. Let's put it that way. The only thing that takes me out of that is probably a film. I watch a lot of movies.

I was a guest at CalArts. John Baldessari invited me out a few times. I've been there. I've been in Pasadena, taught out at Boulder, University of Colorado. And I've taught in Europe. I've lectured and taught. I've taught at the École des Beaux-Arts in Nigne [sp]. I was there for a couple of weeks, I was there. I've taught all over - in Switzerland, Germany.

I may have a lot of political opinions but it doesn't necessarily come into my work. I keep the two worlds separate.

I made films from the - when I was a little kid, my father bought me a movie camera. I just wanted to. I don't know how. You just learn, you just do it. You just do it.

After I did the drawings of trees combining them with words, I started doing - I did that for a very short time. Then it kind of - that sort of evolved into just showing the branches of a tree coming down into the trunk and then going into the root system. So I showed both the branches and the roots of a tree, which were about equal. There is as much going on under the ground as is going on above the ground, which you can see.

And we live in a kind of realm of language and words and so forth. So we can sort of relate to them. They don't exist without us. We create words.

I wanted my style to be very recognizable.
