人生太短，不应该浪费时间与平庸者交朋友。
On choosing friends: "Life's too short to hang out with people who aren't resourceful."
Conflict is the gadfly of thought. It stirs us to observation and memory. It instigates to invention. It shocks us out of sheeplike passivity, and sets us at noting and contriving.
——〈在广州大本营国民党员的演说〉，1923年11月25日
为人高傲自夸，喜欢独断专行，这是行事办事的祸患。
Memory is identity... You are what you have done; what you have done is in your memory; what you remember defines who you are.
