"I'm so tired of these struggles. I just want to disappear."

"I often think I am very stupid, but when I look at what others are doing, I think I am a genius."

"I'm working like a madman, but I'm not satisfied with anything."

"It is a tragedy that we live in a world where physical courage is so common, and moral courage is so rare."
