世界上最珍贵的两个字是勤奋和坚持。勤奋的人改变自己，坚持的人改变命运。
很多事情，不是因为看到希望才去坚持，而是因为坚持了才会看到希望。

The most precious words in the world are diligence and persistence. Diligent people change themselves. Persistent people change their destiny.
For many things, it is not because we hope that we persist, but because we persist that we see hope.
