Is it ever OK to be a quitter?

I realized that often people quite when they are in a tough situation.Quitting does no good to you or anybody. A quitter to me is like a loser. When people quite it tell me that they have no brain and can't think of a way to finish off what their doing, which is upset. Even if it is difficult, try your best on it. Never quit until you have give your BEST effort and sometime you might get lucky. Sometime people say bad stuff to let you quite and they say that they don't need you. If they think that, they are totally wrong!Maybe after you quite they might realized that it is hard to loses a person(especially in a sport game). In the novel, The Fighting Ground, Johnathan ran away from the Hessian and was safely found by the Corporal and his men. a day ago Jonathan is a risk-taker and a minute later he is a quitter. this can be seen on pg121 " ' i want to go home'. "Even if he is tried and can't do anythings he still have to help the Corporal fight the Hessian because he is acceptable as a member of his army. This can be seen on pg 123" 'We're going to finish this first ' he said ' And you're going to help. You're needed.' " Truly, quitting are not a way to improve yourselves.
