纵然伤心，也不要愁眉不展，因为你不知是谁会爱上你的笑容。
No arts; no letters; no society; and which is worst of all, continual fear, and danger of violent death; and the life of man, solitary, poor, nasty, brutish, and short.
The end of wisdom is to dream high enough to lose the dream in the seeking of it.
永远不要停止学习，因为生活永远不会停止教导。
