已经拥有许多而想拥有更多的人，其失意感耍大于一无所有而只想拥有一点点的人。另外，只缺一样东西的人也会比缺很多东西的人更不满。

你跑得越多，他们追得越紧。

False happiness renders men stern and proud， and that happiness is never communicated. True happiness renders them kind and sensible， and that happiness is always shared.

The only thing I can say is that I try to be humble all the time.
