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 first place I try to go when I have free time is the museums. I'm a big museum person.

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 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.

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.

How does any idea come to your mind? I don't know.

I am good in the fact that most of my reviews have been very positive really. I get pretty good reviews. There have been some that aren't - critical. I think they are extremely - the people that wrote them really don't understand what they are looking at quite frankly or have a very preconceived notion of what conceptual art should be or where I am at or the fact that I may change what I have done from what I did 20 years ago. But there is always some reason that they just sort of get it wrong. And so it certainly doesn't affect my work.
