Confucious said that real knowledge is knowing the extent of one's ignorance.Aristotle and Socrates said the same thing.Is it a skill that can be taught or learned? It probably can, if you have enough of a stake riding on the outcome...

光线不断变化，每分钟都在改变事物的氛围和美感。

译文：人世间能够享有千金产业的，一定是个拥有千金福报的人；享有百金产业的，也必定是有百金福报的人；遭到饿死的，也绝对是命中注定应遭饿死果报的人。上天只不过是就每个人所造作的善恶质性，厚实恰当地来对待他，使他获得应有的结果而已，何曾加上一丝毫喜好或厌恶的念头?

今天很残酷，明天更残酷，后天很美好，但绝对大部分是死在明天晚上，所以每个人不要放弃今天。

It’s not just what you say that stirs people. It’s the way that you say it.
