There is definitely power in numbers. Take for instance, a band or orchestra. Each member performs their specific role and responsibility and contributes to the whole unit to make music in a way that couldn't be accomplished without everyone working together. Consider a basketball team. If you place one very talented player against a group of five mediocre players, it's pretty unlikely that one player could win the game. You need teammates to be successful in the game.
What is your worst team experience? Why was it so bad? What could have been done to make it a more positive experience?
