心理学必须是一门描述的科学，而非解释。
Psychology must be a science of description, not explanation.
庆祝你的成功。在失败中找到幽默。不要把自己看得太严肃。放松，你周围的人也会放松。享受乐趣。总是表现出热情。
There is no reason why good cannot triumph as often as evil. The triumph of anything is a matter of organization.
SILENCE. Speak not but what may benefit others or yourself; avoid trifling conversation.
