The best investment you can make is in yourself.

我们之所以能够感知事物的变化，是因为单子在无限的变化中保持了稳定的内在本质。

Never use a credit card for credit. The only kind of credit， or debt， that is acceptable is debt to acquire something whose exchange value is extremely likely to increase， like in a home. The exchange value of most things diminishes or vanishes the moment you purchase them. Don’t be in debt to losers.

最好的设计是解决人们甚至没有意识到的问题。
