The only sensible ends of literature are, first, the pleasurable toil of writing; second, the gratification of one's family and friends; and lastly, the solid cash.

晏子春秋

开始时有一点差错，结果会造成极大的错误。

在每个方程中，都有一个等待被讲述的故事。

It is always good to have a problem that you cannot solve. It means you have something to work on.

When speaking to an audience it’s better to fix your gaze on a few people than to “spray” your gaze across the room. Your eyes telegraph to others whether you really believe what you are saying.

Writing is a way of preserving the ephemeral.
