The fittest and strongest individuals can achieve the greatest success in sports. Many people would agree that the healthier and stronger one is the greater success he or she can obtain. In fact, because athletes need to spend a big amount of time to take extra training and only a strong and healthy body can bear these physical challenges. In many champions we saw were always the healthiest and strongest among all the players. However, I do not believe that physical condition is the only factor to achieve success in sports. I would argue no matter it is sport, art or music, an important thing to success is diligence. That is why most of the greatest athletes start professional training since they were small. There are a lot of successful cases shows us that even a person don’t have the perfect physical quality in nature, trough continued training and exercises, he or she could perform even stronger than the ones who used to be stronger than them. Den Yapin is a good example. She is only 155 cm high and most of people believe that she will never be a good athlete on playing table tennis, but, at last, she became the world champion due to her hard work. In addition, some people think that psychological quality is also important to get success. For example, there are two football players whose ability and skills are in the same level. In one game the final score is 1 to 1, so, it came to penalty shoot-out. One of them wins. Is it because that the other one is not good as the winner? No, it isn’t. It is psychological quality that makes different. All in all, I believe that an excellent player or team should not only have diligent training and practice, but also a good psychological quality.
