Spend each day trying to be a little wiser than you were when you woke up.Discharge your duties faithfully and well.Systematically you get ahead, but not necessarily in fast spurts...At the end of the day if you live long enough most people get what they deserve.
每天都要努力变得比起床时聪明一点。忠实而出色地履行职责。你会有条不紊地出人头地，但不一定会一蹴而就......最后，如果你活得足够长，大多数人都会得到他们应得的。
剑鞘保护剑的锋利，自己却满足於它自己的迟钝。
测量可测量的，并使不可测量的成为可测量的。
预测未来的最好方法就是创造未来。
