The purpose of mental activity is successful living.

I always believed that when you follow your heart or your gut, when you really follow the things that feel great to you, you can never lose.

聪明用在正道上，越聪明越好，文采名声会帮助他事业渐进；聪明用在邪路上，越聪明越坏，文才名声只助长其伪诈丑行。

The past is never dead. It's not even past.

The present state of the system of nature is evidently a consequence of what it was in the preceding moment, and if we conceive of an intelligence which at a given instant comprehends all the relations of the entities of this universe, it could state the respective positions, motions, and general effects of all these entities at any time in the past or future.

When someone really hears you without passing judgment on you, without trying to take responsibility for you, without trying to mold you, it feels damn good!
