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.

创新不仅仅是关于新想法，而是以创造真正价值的方式去执行它们。

幸福的秘诀是面对这个世界很可怕的事实。

健康的一天胜过生活的千年。
