知道事情做不成于是就听之任之，这是聪明人的方法；知道事情做不成而竭尽全力的，这是忠臣孝子之心。
The world is made of words, and if you know the words the world is made of, you can make of it whatever you wish.
The most enduring changes come from understanding the root causes of problems, not just their symptoms.
【译文】杀人一万，自己也要损失三千。说一句伤害别人的话，就像用刀割别人的心一样。
