In every large organization, where the men in control have considerable power, there are other less prominent men (or women) who acquire influence over the leaders by personal methods. .. but in general they prefer not to take the front of the stage. They are men who love power more than glory. .. The qualities required for power behind the scenes are very different from those required for all other kinds, and as a rule, though not always, they are undesirable qualities.
