Don't stop to paint the material, but push on to give the spirit.

Do not worry about your originality. You could not get rid of it even if you wanted to.

There are people who buy pictures because they were difficult to do, and are done. Such pictures are often only a record of pain and dull perseverance. Great works of art should look as though they were made in joy. Real joy is a tremendous activity, dull drudgery is nothing to it.

Those who cannot begin do not finish.

Art cannot be separated from life. It is the expression of the greatest need of which life is capable, and we value art not because of the skilled product, but because of its revelation of a life's experience.

Art appreciation, like love, cannot be done by proxy: It is a very personal affair and is necessary to each individual.

There is weakness in pretending to know more than you know or in stating less than you know.
