Every intervention should leave things better than we found them.

The only way to find true happiness is to risk being completely cut open.

The best way to predict the future is to invent it.

To be a writer is to sit down at one's desk in the chill portion of every day, and to write; not waiting for the little jet of the blue flame of genius to start from the breastbone.

Success is walking from failure to failure with no loss of enthusiasm.

吃饭不可不嚼便咽，走路不可不看便走，话不可不考虑便信口乱说，事不可不计划就贸然去做，衣服不能随便就脱，钱财不能随便据为已有，怒气不可不忍而任意发作，朋友不可不加选择地乱交。
