To know how to grow old is the master work of wisdom, and one of the most difficult chapters in the great art of living.
知道如何变老是智慧的杰作，也是伟大的生活艺术中最难的章节之一。
A LITTLE ENCOURAGEMENT
给此刻的你，一点向前的力量。
关于学习、善意与成长，读一句，再想一想。
Gratefulness is the key to a happy life that we hold in our hands, because if we are not grateful, then no matter how much we have we will not be happy -- because we will always want to have something else or something more.
感恩是我们拥有幸福生活的关键，因为如果我们不感恩，那么无论我们拥有多少，我们都不会快乐，因为我们总是想要拥有其他的或更多的东西。
A mistake isn’t a mistake unless it can’t be put right.
错误不是错误，除非它无法纠正。
