Conciseness in art is essential and a refinement. The concise man makes one think; the verbose bores. Always work towards conciseness.
There is only one true thing: Instantly paint what you see.
One must be of one's time and paint what one sees.
You must always remain master of the situation and do what you please. No school tasks, ah, no! no tasks!
Above all, keep your colors fresh!
The attacks of which I have been the object have broken the spring of life in me... People don't realize what it feels like to be constantly insulted.
