It's better to burn out than to fade away.

Always say less than necessary.

一个人不应该发愁没有官位俸禄，而应该发愁没有为官的本领。不应该发愁别人不了解自己，而应追求能够让别人了解自己的才能。

But who prays for Satan? Who, in eighteencenturies, has had the common humanity to pray for the one sinner that needed it most?（From Jane Lampton Clemens）

Mathematics is not a careful march down a well-cleared highway, but a journey into a strange wilderness, where the explorers often get lost.

科学是一项协作的努力，重大的发现不会孤立地发生。

安全总是过度的，直到它不够为止。
