The painter's obsession with his subject is all that he needs to drive him to work.

A painter's tastes must grow out of what so obsesses him in life that he never has to ask himself what it is suitable for him to do in art.

A painter must think of everything he sees as being there entirely for his own use and pleasure.

The picture is all he feels about it, all he thinks worth preserving of it, all he invests it with. If all the qualities which a painter took from the model for his picture were really taken, no person could be painted twice.

The model should only serve the very private function for the painter of providing the starting point for his excitement.

The painter must give a completely free rein to any feeling or sensations he may have and reject nothing to which he is naturally drawn.
