Generalised anger and frustration is something that gets you in the studio, and gets you to work - though it's not necessarily evident in anything that's finished.

In art, the only one who really knows whether what you've done is honest is the artist.

I thought I might have to give up art, but I couldn't think of anything else to do.

And I don't have any specific steps to take because I don't start the same way every time. But there is a knowing when it's enough and you can leave it alone.

My work is basically an outgrowth of the anger I feel about the human condition. The aspects of it that make me angry are our capacity for cruelty and the ability people have to ignore situations they don't like.

I'm surprised when the work appears beautiful, and very pleased. And I think work can be very good and very successful without being able to call it beautiful, although I'm not clear about that. The work is good when it has a certain completeness; and when it's got a certain completeness, then it's beautiful.

What is it that an artist does when he is left alone in his studio? My conclusion was that if I was an artist and I was in the studio, then everything I was doing in the studio should be art . . . . From that point on, art became more of an activity and less of a product.
