Competition and cooperation seem to be two apparent opposites, which people have to choose between. In my opinion, competition and cooperation play equally important roles in modern world. We should not only learn how to compete, but also how to cooperate.
In modern world, competition still serves as a significant stimulus for people. The fittest survived and the society developed. Good interpersonal relations can facilitate one's success. However, people who believe that competition is more important than the cooperation partially or completely neglect the importance of copperation which in my mind contributes equally to the development of human society.
All in all, no man is island，we can safely conclude that competition and cooperation are equally important to the social development. The over-emphasis on or the neglect of either will cause losses and even damages.
