It is only too true that a lot of artists are mentally ill - it's a life which, to put it mildly, makes one an outsider. I'm all right when I completely immerse myself in work, but I'll always remain half crazy.

The diseases that we civilized people labor under most are melancholy and pessimism.

What lives in art and is eternally living, is first of all the painter and then the painting.

Painting is like having a bad mistress who spends and spends and it's never enough ... I tell myself that even if a tolerable study comes out of it from time to time, it would have been cheaper to buy it from somebody else.

There is no blue without yellow and without orange.

Exaggerate the essential, leave the obvious vague.

In spite of everything I shall rise again: I will take up my pencil, which I have forsaken in my great discouragement, and I will go on with my drawing.
