“As with many of the dichotomies of leadership, a person’s biggest strength can be his greatest weakness when he doesn’t know how to balance it.  A leader’s best quality might be her aggressiveness, but if she goes too far she becomes reckless.  A leader’s best quality might be his confidence, but when he becomes overconfident he doesn’t listen to others.”
