The modern society is the one full of competitiveness, which make many smart people ward others off. They believe in the principle of “Two of a trade never agree”, in fact, it's totally misunderstood.
Competitiveness is evitable between people and groups. We cannot avoid it as long as we strive for survival and development. At the same time, the interests between us are close and intangible in our community. We have to compete in cooperation and cooperate in competition for the shared interests. One chopstick may be easy to break off while a bunch of them may not, which full reflects how powerful the cooperation is.
We make progress because of competition and we gain a lot more because of cooperation. With competition and cooperation, we can combine our advantages with that of others so as to achieve a win-win result. There is a famous saying goes like this: One single flower does not make a spring but a garden of flowers does.
