And yes, there are things I want to keep, that I like around me - especially when there's very little left. I just want to keep those little bits of reminders of my past. There are certain drawings from the '60s; certain little paintings from the '60s that I keep.

The idea of, say, the compressed space between the floor and the object hanging over it and then the long space between the object and the ceiling was a kind of interesting idea for me - the idea of compressing and expanding. That was an idea that I worked with, which you could only do sculpturally. You can't really do with a painting on the wall.

I am a very lucky artist in the sense that I have had all my life a lot of opportunities to do what I want to do.

The idea of the culture that you live in determining meaning in your art, though, is a very important aspect of what art would be about. But that had more to do with the kind of general understanding of what the hell you're doing, you know.

I mean, part of the justification for art is art history, the fact that you're part of this tradition. You can't really operate outside of it. So looking for what this work is really about, if I look at Velázquez, if I look at Las Meninas or The Tapestry Weavers [1657] or something and really study it and try to figure out what that painting is really about, then I find relationships between what I'm trying to do and what he was doing.

I took art courses, only in the sense that I was able to - I took art classes, which were fun, which I liked, but it was a - just a kind of a general education that I got, a regular academic - academic diploma, but I kind of had the feeling that art was something that I really liked the most but I wasn't really sure that that was it.

I don't really use still photography very much anymore except to document my work.
