I think words speak to us even though they may be written on a wall. So we hear them in our mind. We say it to ourselves. But they are also visual things. You draw them. They are designed. They are colored. They have a certain size. I put them in a certain place. So they are objects that have to be - artistic decisions have to be made in terms of the color and the size and the line and whatever.

Agnes Martin is a big influence in my work actually, when I first saw her, these fine grids.

The words represent ideas first of all. That is something you have to understand. I mean, it is not just an object, but it is an object with a history and it is loaded with all kinds of implications and ideas. They exist in the world in a very special way. So they kind of represent some aspect of the world that we perceive, as do photographs, as do drawings of trees or whatever. And they are not a one to one. They are not the world, but they kind of refer to the world and they also exist in the world.

So I never had trouble getting work or working or doing - I always worked. I worked when I went to college. I worked after school.

I wanted my style to be very recognizable.

Most of the criticism of my work was pretty good, but occasionally it would not be. And I just sort of felt that they absolutely didn't get what I was doing. It was their limitations on what they thought art should be or what they thought my work should be in relation to earlier work or whatever.

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