我返老还童了。

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.

真正的勇气是直面自己的弱点，并拼尽全力改变它。

幸福不是现成的东西，它来自于你自己的行动。

We don't inherit the earth from our ancestors; we borrow it from our children.

People who learn to control inner experience will be able to determine the quality of their lives, which is as close as any of us can come to being happy.
