I never considered myself a performance artist.

Thinking has an understructure and underpinnings.

I had drawings that were the first time that mathematics was put into visual form.

Public art existed all along, but ecological art just naturally grew out of my thinking and writings in that area for years. I didn't get involved in it; I started what then became a movement.

One thing that's paramount in my life is that I am alone. I'm a loner. And yet I have many friends and I don't feel lonely. And I even like my own company. But when I'm alone, it's to read or write. I'm in my thoughts. Mostly I'm learning.

I always was alone. And I'm alone today. It's fine. I have lots of friends, but not in terms of working together.

I wish I didn't have daily problems to deal with, so that I could just concentrate on learning more, every single day.
