The Feb. 13th edition of the Chronicle of Higher Education had an article on Sue Ferguson Gussow, who teaches freehand drawing at Cooper Union. When she was warning students about overdrawing, she said, "Every drawing, every painting, is really about the next painting anyhow."
I have been trying to understand what that means. It strikes me as being true. We make choices when we draw or paint. We must live with them, and not try to introduce the choices we didn't make in the same work. We can save them for the next painting. I am certain there are other ways of looking at it as well.
