I painted [circa 1960-62] through the whole history of art toward abstraction. I painted like crazy [and] I had some success with all that, or gained some respect. But than I felt it wasn't it, and so I burned the crap in some sort of action in the courtyard. And then I began. It was wonderful to make something and then destroy it. It was doing something and I felt very free.
