People are always trading their excess for somebody else's excess. One country has a lot of aluminum so they trade aluminum for sugar. It's the law of supply and demand.

I was one of the first post-studio artists. I used to do my works in the streets. I used to find them in the streets, and I used to leave them in the streets.

I was never good at painting. The great turning point came when I had a block of wood and I carved a shape into the wood and put a small piece of timber into that space - like a negative - and so it made an endless column, only inward.

I had no place to put anything. I would give my sculpture away because I had no place to put it.

I think my work is very American because I'm American. But I found that Europeans like uncertainty and doubt.

A man climbs a mountain because it is there. An artist makes a work of art because it is not there.

An artist, to achieve anything in art, has to finally do the thing that nobody else wants to do and nobody else has thought to do.
