"You never really understand a person until you consider things from his point of view."

只要对人情世故熟悉了，还有什么大事做不到？只要天理与人心吻合了，还有什么好事办不成？如果对某一件事情不留心，那么这件事情就得不到应有的料理；如果对某一物品不留心，那么这个物品就得不到合理的安排。

我不是榜样，我是个角色扮演者。

Believe in your ideas, even if no one else does.

A good mathematician should be both rigorous and imaginative.
