As Will Rogers would have said, "There is no such thing as a free variable."

你最不满意的客户是你最好的学习来源。

The privilege of a lifetime is to become who you truly are.

The best way to get a project done faster is to start sooner.

客户的忠诚是赢得的，而不是给予的。

商业成功和环境责任可以而且应该齐头并进。

【讲解】：我十五岁时开始立志学习，三十岁时能立足与社会，四十岁时能通情达理遇事不再疑惑，五十岁时懂得了天命的道理，六十岁能听的进不同的意见，到了七十岁时已经达到随心所欲，想怎么做就怎么做，也不会超出规矩。
