Q.The expression “Never, never give up” means to keep trying andnever stop working for your goals. Do you agree or disagree with thisstatement? Use specific reasons and examples to support youranswer.

Some people say that we can produce nothing if we give up. I cannot agree with this argument, because it overlooks some disadvantages of itself and advantages of the counter. I try to explain them one by one.
First, if it is impposible to reach the goal, choosing to never give up leads to disappoint youawfully. There is the risk that we cannot get to the right result in theory. That would hurt us so muchthat we cannot stand it.
Second, if we sometimes choose to give up, we can try more subjects or themes than sticking to one thing. For example, in my major, economics, much theme exist. Though I can keep trying foreverfor one theme, I choose to try as many themes as possible because I might be able to find more exciting and interesting affairs. In addition, what seems to be absolutely different can be sometimes clues for reach the goal. Leaving from it once might lead us to the goal.
In conclusion, I disagree with the "never give up" strategy. We should try other possibilities, if there exist.
