Making art depends upon noticing things things about yourself, your methods, your subject matter. Sooner or later, for instance, every visual artist notices the relationship of the line to the pictures edge. Before that moment the relationship does not exist; afterwards its impossible to imagine it not existing. And from that moment on every new line talks back and forth with the pictures edge. People who have not yet made this small leap do not see the same picture as those who have in fact, conceptually speaking, they do not even live in the same world.
