"A man is rich in proportion to the number of things he can afford to let alone."

The only thing worse than being alone is being with the wrong person.

The worst evils in history have always been committed by those who truly believed they were combating evil. Beware of combating evil.

宇宙即变化；我们的生活由我们的思想塑造。

人是自己的囚犯。

I don’t need a map, I make my own path.

The more we learn about black holes, the more we realize how much we still don’t know.
