一切幸福都绝非没有忧虑和烦恼，而一切逆境也绝非没有慰籍与希望。

We must design technology with empathy and purpose.

For in the final analysis, our most basic common link is that we all inhabit this small planet. We all breathe the same air. We all cherish our children's futures. And we are all mortal.

幸福的幸里面是一个“幸”，不是一个“辛”。  或者理解成，Y=Why=为什么，I=我。幸福里面没有为什么，只有我。 

"Every book is a journey, and every journey changes us."

"Das Geheimnis der Freiheit ist der Mut."

常识就是人到十八岁为止所累积的各种偏见。
