商业成功源于比任何人都更了解你的客户。
Success in business comes from understanding your customers better than anyone else.
容易愤怒就会伤害别人；私欲太多了就会害了自己；贪图安逸就会有害于自己的品德；忧虑太多，就会削弱自己的意志。
A mathematician's work is never truly finished; there is always more to explore.
Don't write your name on sand, waves will wash it away. Don't write your name in sky, wind may blow it away. Write your name in the hearts of people, that's where it will stay.
The only thing I can rely on is my own perception, and that is always changing.
The more you know, the more you suffer.
