There is a saying said that don't give up forever.When I was a child,my teachers often told that don't give up,and the hope was always there. 

Whenever we meet with a problem,however hard the problem is,we shouldn't stop our work.We must have a faith that the most beautiful view will come in after the most high hill.There are also many examples,such as Zhang Haidi,Zheng ZHihua,Helen Keller and so on,they all had a bad life,but they all successed by their efforts.
In a word,if we have dreams,we should do our best to come true our dreams,we shouldn't give up!
