人们害怕他们不理解的东西，憎恨他们无法征服的东西。

Kindness is the key to happiness.

"The act of creation is an act of defiance against the void."

译文 ：防御欲念好比牵挽逆水而行之船，刚一歇息，船就要向下游漂流；努力向善好比攀爬没有树枝的大树，刚一歇脚，身体就要下滑。因此，君子的内心无时无刻不是处在警惕之中

Without some goals and some efforts to reach them, no man can live. What we call life is a journey, and the journey itself is home.
