"Don’t try to make life a mathematics problem with yourself in the center and everything coming out equal. When you’re good, bad things can still happen. And if you’re bad, you can still be lucky."

A proof is a way to convince yourself and others that something is true.

The legacy we leave for future generations depends on the choices we make today.

规模不等于价值，精准才是关键。

做好事如同背负重物而登山，志向虽已确立，但总是担心力不从心；干坏事如同骑马下山，虽然未加鞭，但却欲驻足而难以自禁。

I write to make sense of my own existence.

To write is to give voice to the voiceless.

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.
