<We must learn about losing>

 There were many wars in the world. Some countries lost many times, but some countries won many times. In Korea, there were more than 960 wars. Korea usually won in the war, but sometimes Korea lost. For example, there was Mongol invasion. Mongol was the largest country in world history, so Korea could not defeat Mongol. Losing might not be happy, but we should learn about losing. If we don't learn about losing, we will be proud to ourselves. Self-esteem is important, but it is not always good. We will think that we are the best and we will be defeated by enemies. Losing can make people sad, but learning about losing is important to us.
