Our evolved psychology is the foundation of all culture, not the other way around.

Nothing is certain， and nothing is impossible.

The only way to understand another culture is to assume the frame of reference of that culture.

 释义：有才华的人必须要勤于修养，懂得收敛，就好比未经提炼的金玉，虽看起来灰暗无光泽，但日久便会焕发光彩。

The personal is universal, and the universal is personal.
