“Life is painting a picture, not doing a sum.”

Herschel Browning Chip (1968, p. 267)
Other translation:
Formerly pictures used to move towards completion in progressive stages. Each day would bring something new. A picture was a sum of additions. With me, picture is a sum of destructions. I do a picture, then I destroy it. But in the long run nothing is lost; the red that I took away from one place turns up somewhere else.

Context: The Art of painting is itself an intensely personal activity… a picture is a unique and private event in the life of the painter: an object made alone with a man and a blank canvas... A real painting is something which happens to the painter once in a given minute; it is unique in that it will never happen again and in this sense is an impossible object... And it is something which happens in life not in art: a picture which was merely the product of art would not be very interesting and could tell us nothing we were not already aware of. The old saying, “what you don’t know can’t hurt you”, expresses the opposite idea to that which animates the painter before his canvas. It is precisely what he does not know which may destroy him.

Somebody once said that I paint the kind of girls your mother would want you to marry.
