I believe more and more that God must not be judged on this earth. It is one of His sketches that has turned out badly.

The world concerns me only in so far as I feel a certain indebtedness and duty toward it because I have walked this earth for thirty years, and, out of gratitude, want to leave some souvenir in the shape of drawings or pictures — not made to please a certain taste in art, but to express a sincere human feeling.

I am unable to describe exactly what is the matter with me; now and then there are horrible fits of anxiety, apparently without cause, or otherwise a feeling of emptiness and fatigue in the head.

And in a picture I want to say something comforting, as music is comforting.

Your profession is not what brings home your weekly paycheck, your profession is what you're put here on earth to do, with such passion and such intensity that it becomes spiritual in calling.
