People always say that no pay, no gain. It seems if people work hard and fight for their goals, then they will get what they want. Actually, life will not always go as their will, and most people have worked so hard, but they still can’t reach their goals. Then it is natural for them to question about what they do, and they believe that it is useless and waste time. I don’t agree with them. I believe that what we learn will not be useless, someday these can help us to go further and make us the strong people. So there is no use to feel frustrated when the efforts we have make do not work, it will work someday.
