The mathematician does not study pure mathematics because it is useful; he studies it because he delights in it and he delights in it because it is beautiful.
数学家研究纯数学不是因为它有用；他研究它是因为他喜欢它，他喜欢它是因为它美丽。
The dream of every dictator is to turn his country into a prison without walls.
贫穷的时候最能表现出一个人是否清廉，富裕的时候最能表现出一个人是否讲求仁义。
These walls are really interesting. At first you hate it, then you get used to it. After a considerable period of time, you will depend on it.
诀窍是关注你周围发生的事情并继续写作。
