I am pessimistic about a picture's power to be the emissary of just one thing. What I hope is that the picture says, "Here I am, this is what I am like," and the person seeing the picture says in return, 'You know a lot but you don't know half of what I know.'

As a good picture would come, I would never know exactly what I had done. When you did see it, it would strike you as a great surprise - who did that? How did it happen? Being surprised by your own work makes you both less serious and have serious reverence.
