“Pretend you are dancing or singing a picture. A worker or painter should enjoy his work, else the observer will not enjoy it.”

“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.”

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

“The most vital things in the look of a landscape endure only for a moment. Work should be done from memory; memory of that vital moment.”

“Time extracts various values from a painter's work. When these values are exhausted the pictures are forgotten, and the more a picture has to give, the greater it is.”

“Don't worry about your originality. You couldn't get rid of it even if you wanted to. It will stick with you and show up for better or worse in spite of all you or anyone else can do.”

“Good composition is like a suspension bridge; each line adds strength and takes none away... Making lines run into each other is not composition. There must be motive for the connection. Get the art of controlling the observer – that is composition.”
