概率是基于部分知识的预期。

The best way to measure how much you've grown isn't by inches or the number of laps you can now run around the track, or even your grade point average - though those things are important, to be sure.It's what you've done with your time, how you've chosen to spend your days, and whom you've touched this year. That, to me, is the greatest measure of success.

在热闹繁华中如果能够保持理性，才不至于迷失，也就省去了许多徒慕虚荣的苦心；困境中，在人生的低谷期，若能保持一份乐观，才会有一番更为真切的人生感悟。
