世界是一个舞台，我们只是演员。

The ability to be alone is the ability to love. It may look paradoxical to you, but it's not. It is an existential truth: only those who can be alone are able to love, to share, to go into the deepest core of another human being—without possessing the other, without becoming dependent on the other, without reducing the other to a thing, and without becoming addicted to the other.

勤勉：不要浪费时间，只做有用的事情，戒除一切不必要的行为。
