Difficult circumstances serve as a textbook of life for people.

解放自己是一回事，拥有那个解放了的自我则是另一回事。

The details are not just details; they make the product.

Psychology is a science, and teaching is an art; and sciences never generate arts directly out of themselves.

译文：了解人情世故就是一门学问，能应付人情世故就是好文章。赏析：我们要学会洞悉人性，洞察人心，要善于向书本学习，向社会学习，悟透人情世故，处事圆滑，才能走得更远。
