一个人笑的时间是与众神共度的时间。

像明天就要死去一样活着，像永远活着一样学习。

Own only what you can always carry with you: know languages, know countries, know people. Let your memory be your travel bag.

In the stock market, the most important thing is not to predict the future, but to understand the present.

孔子说：“知道学习不如喜欢学习，喜欢学习不如以学习为快乐。”
