"Gerhard Richter: The Daily Practice of Painting," MIT Press, 1995:

Notes, 1973--

' The centre cannot hold': accept this willingly, along with the loss of consensus and attitude and individuality.
Be a reaction machine, unstable, indiscriminate, dependent.
Sacrifice oneself to objectivity.
I have always loathed subjectivity. Even failure, poor quality, opportunism and lack of character are a small price to pay in order to produce something objective, definitive, universal, right.

February. One has to believe in what one is doing, one has to commit oneself inwardly, in order to do painting. Once obsessed, one ultimately carries it to the point of believing one might change human beings through painting. But if one lacks this passionate commitment, there is nothing left to do. Then it is best to leave it alone. For basically painting is total idiocy.
