Great to be Collaborative but you certainly need Competitive to be the best. There are several domains in real time life & competitive markets where many participants are playing & yet each participant has to vigorously pursue own self-interest for success. Whilst 'collaboration' is a very sanctified social value & 'collective goals' is an unspoken norm, winning in real life competituve events is an outcome of superior individual performance. Competitive markets necessitate that there should be many competitors for same resources. However, each participant has to vigorously pursue own interest.Only then in such competitive systems, the best possible economic outcome occurs & collectively,the market benefits. Adam Smith rightly said that it is not for the banevolence of the butcher, the brewer or the baker that we expect our dinner, but from their regard to their own interest. "Mechanics of economic analysis has established that when all economic actors seek what is best for each one of them individually that production costs are minimised, right quantity of goods are produced & prices, including wages are determined fairly"(Jeffrey Pfeffers). Never therefore undermine the role & value of individual competitive efficiency in your success.
