Psychology is the science of mental processes.

勇敢是一种德行，不仅在战斗中，在生活中的各个方面都需要勇敢。

人类最基本的欲望是被承认为一个人。

最重要的是保持开放的心态。

The end of history will be a very sad time. The struggle for recognition, the willingness to risk one's life for a purely abstract goal, the worldwide ideological struggle that called forth daring, courage, imagination, and idealism, will be replaced by economic calculation, the endless solving of technical problems, environmental concerns, and the satisfaction of sophisticated consumer demands.

我们是我们反复做的事情。因此，卓越不是一种行为，而是一种习惯。

"The best way to predict the future is to create it."
