幸福不是现成的东西，它来自于你自己的行动。

In the wild, there are no second chances. You have to get it right the first time.

To overcome the anxieties and depressions of contemporary life, individuals must become independent of the social environment to the degree that they no longer respond exclusively in terms of its rewards and punishments.

唯一真正的智慧在于知道你一无所知。

成功的路上没有捷径，只有不断努力。
