 Life is sad at times, but it is up to you to make your own life happy. 生活有时是令人沮丧的，但你可以努力让自己的过得开心。

 You are the only exception. 你是唯一的例外。

 Age wrinkles the body. Quitting wrinkles the soul. 岁月使皮肤起皱，放弃使灵魂起皱.

 For something,we can't understand when we are young but by the time we understand,we are no longer young. 有些事情，当我们年轻的时候无法懂得，当我们懂得的时候已不再年轻。
