人生最重要的事是停止说“我希望”，开始说“我会”。

The human being cannot live in a condition of emptiness for very long: if he is not growing toward something, he does not merely stagnate; the pent-up potentialities turn into morbidity and despair, and eventually into destructive activities.

心理学是精神生活的科学，而不仅仅是其元素的分类。

真相不止一个，每个人都有自己的真相。
