The purpose of life is not to be happy. It is to be useful, to be honorable, to be compassionate, to have it make some difference that you have lived and lived well.

成功不在于你赚了多少钱，而在于你对人们生活的影响。

成功在于做出正确的选择，而不仅仅是努力工作。

There is no easy walk to freedom anywhere, and many of us will have to pass through the valley of the shadow of death again and again before we reach the mountaintop of our desires.

You have to be fearless in order to succeed.
