人不是为失败而生。一个人可以被毁灭，但不能给打败。

The deepest problems of modern life derive from the claim of the individual to preserve the autonomy and individuality of his existence in the face of overwhelming social forces, of historical heritage, of external culture, and of the technique of life.

晏子春秋

我们必须始终质疑我们的假设，并愿意根据新的证据修订我们的理论。

Good design is invisible; you only notice it when it's bad.
