Similar to the fact that the best athletic coaches are often those who were not superstars as players, people who possess average charisma and/or personality have the potential to be truly superior leaders. These types of people have had to work hard for their successes and have a clear understanding of the followers' mindset. In fact, Wren (1995) suggests that charisma often becomes a leader's undoing. Just as superstars are often too "full of themselves" to be effective coaches, so too are leaders whose charisma narcissistically "gets in the way" of effective leadership. In fact, although a certain amount of charisma is a plus, charismatic leaders are not necessary "to influence followers to comply with and carry out the vision of the leader. Rather, the vision itself needs to reflect and draw upon the vast resources contained within individual employees" (Wren, 1995, pp. 219-220). "Regardless of personal style, an individual can be inspirational to a good portion of colleagues" (Zenger, 2009, p. 20). Hence, even if a person is perceived to have only an average personality, he/she can have a dedicated following through trust and credibility.
