A company can not work if it is all Superstars. Teams and departments need a balance of agressive, energetic people, and quiet solid workers. If a team or department is made up of all superstars, then there is usually intra-departmental fighting andnothing gets done; it's usually due to the strong personalities and conflicts. A company that is made up of a mix of personalities and skills will accomplish more through the synergy of the team in place. See book "Teams in the Workplace" for more information.
