计算机科学不仅仅是关于计算机的，就像天文学不仅仅是关于望远镜的。

The proper function of man is to live，not to exist.

When you are young spend at least 6 months to one year living as poor as you can， owning as little as you possibly can， eating beans and rice in a tiny room or tent， to experience what your “worst” lifestyle might be. That way any time you have to risk something in the future you won’t be afraid of the worst case scenario.

我们靠获得的东西生存。但我们靠给予的东西生活。
