Fight with yourself when you paint, not with the model. A student is one who struggles with himself for order.
There is nothing in all the world more beautiful or significant of the laws of the universe than the nude human body.
Paint what you feel. Paint what you see. Paint what is real to you.
Be a warhorse for work and enjoy even the struggle against defeat.
Work always as if you were a master, expect from yourself a masterpiece.
Do not worry about your originality. You could not get rid of it even if you wanted to.
