The only way to have a good day is to start it with a positive attitude.

我是一个乐观主义者。我相信人类智慧的力量能够克服挑战。

The most exciting discoveries often come from paying attention to unexpected results.

False happiness renders men stern and proud， and that happiness is never communicated. True happiness renders them kind and sensible， and that happiness is always shared.

I write because I have no other way to survive.
