种一棵树最好的时间是20年前，其次是现在。

The only way to get through life is to laugh your way through it. You either have to laugh or cry. I prefer to laugh. Crying gives me a headache.

The greatest experiments start with a simple question.

Waste is a design flaw.

我不介意成为一个象征，但我不想成为一个纪念碑。

【译文】 孔子说：“明智的人喜欢水，仁慈的人喜欢山；明智的人好动，仁慈的人好静；明智的人快乐，仁慈的人长寿。”

I'm just a woman. And as a woman， I have no way to make money， not enough to earn a living and support my family. Even if I had my own money， which I don’t， it would belong to my husband the minute we were married. If we had children they would belong to him， not me. They would be his property. So don’t sit there and tell me that marriage isn’t an economic proposition， because it is.
