The power of accurate observation is commonly called cynicism by those who have not got it.

The only real failure in life is not trying.

The truth about a person is often hidden in the gaps between what they say and what they do.

——《致鲁赛尔函》（1906年11月8日）

"The best way to lead is to empower others."

恐惧是底片显影的暗房。
