我不是傲慢，我只是相信我是最好的。

The best books are those that stay with you long after you’ve read them.

No man really knows about other human beings. The best he can do is to suppose that they are like himself.

I don’t believe in luck, I believe in hard work.

That's exhilarating if you're doing well, and very crushing if you're not. It leads, in the worst cases -- in the analysis of a sociologist like Emil Durkheim -- it leads to increased rates of suicide. There are more suicides in developed, individualistic countries than in any other part of the world. And some of the reason for that is that people take what happens to them extremely personally -- they own their success, but they also own their failure.
