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.

The ladder of success is best climbed by stepping on the rungs of opportunity.

【译文】与人说话只能说三分，不能把内心的想法全部吐露给别人。有意栽花花不一定开放，无意去插柳柳树却可能长得茂盛。龙和虎的形态好画，却难以画出它们的骨骼。了解人的表面很容易，但了解人的内心却十分困难。

暴力中没有长存的希望，只能从绝望中得到暂时的解脱。
