Reading Paul Klee’s diaries, I am regularly struck by his insight and seeming general imperturbability.
The evening is indescribable. And on top of everything else a full moon came up. Louis urged me to paint it. I said: it will be an exercise at best. Naturally I am not up to this kind of nature. Still, I know a bit more than I did before. I know the disparity between my inadequate resources and nature. This is an internal affair to keep me busy for the next few years. It doesn’t trouble me one bit. No use hurrying when you want so much.
The evening is deep inside me forever. Many a blond, northern moon rise, like a muted reflection, will softly remind me, and remind me again and again. It will be my bride, my alter ego. An incentive to find myself. I myself am the moonrise of the South.
— The Diaries of Paul Klee: 1898–1918
Even when he was later drafted into the army during WWI, Klee kept this same clearheaded accepting mindset. Some things were out of his control, and always would be. He always had somewhere to climb in depicting his images. The work was always just a reflection of nature and thought.
