But then sometimes you make a catastrophic mistake, you think I am going to kill myself because the sculpture is ruined, but in the end it come out more incredible than had you not made the mistake. This is why I love the rocks. When I sculpt with clay, it feel like cheating. It is too easy. It has no will of its own. The rocks are formidable. They stand up to you. It is a fair fight. Sometimes you win. Sometimes they win. Sometimes when they win, you win.
