I put my heart and my soul into my work, and have lost my mind in the process.

I feel the need of relations and friendship, of affection, of friendly intercourse.... I cannot miss these things without feeling, as does any other intelligent man, a void and a deep need.

What am I in the eyes of most people - a nonentity, an eccentric, or an unpleasant person - somebody who has no position in society and will never have; in short, the lowest of the low. All right, then - even if that were absolutely true, then I should one day like to show by my work what such an eccentric, such a nobody, has in his heart.

Surely the true path is to dive deep into nature.

It astonishes me already when I compare my condition today with what it was a month ago. Before that I knew well enough one could fracture one's legs and arms and recover afterward, but I did not know that you could fracture the brain in your head and recover from that too.

The laws of the colors are unutterably beautiful, just because they are not accidental.

For me work is an absolute necessity, indeed I can't really drag it out, I take no more pleasure in anything than in work, that's to say, pleasure in other things stops immediately and I become melancholy if I can't get on with the work.
