"When you understand human nature, you won't complain anymore."

"When a tree stands tall in the forest, the wind will inevitably break it; when one's conduct surpasses that of others, they will inevitably be destroyed by others."
"All poverty stems from imprisoned thinking; all complaints arise from misunderstanding human nature. If you know nothing about human nature, who will suffer if you don't suffer? Who will be hurt if you aren't hurt? Just as swimming requires understanding the nature of water and taming beasts requires understanding the nature of animals, living in this world necessitates understanding human nature."
"Human nature inherently elevates and belittles; why complain when there is no one to help?"
