The desires， and other passions of man， in themselves， are in his own power； his real difficulties are， to know when they are to be controlled， and when not.

译文：人如果没有长远的考虑，必然会埋下深重的祸根。在灾祸还未萌芽时，又有谁能理解提前预防的心思呢?

生命太短暂，不能浪费在无关紧要的事情上。

You can fool all the people some of the time, some of the people all the time, but you cannot fool all the people all the time.

成功的最好方式是做你自己。
