After analyzing more than three dozen studies of charismatic leadership, Wharton School professor Robert House concluded that “expressing high performance expectations” of people while “communicating a high degree of confidence” in their ability to meet those expectations was the hallmark of charismatic leadership. Think of the people you want your charisma to impact. What standard would you like them to live up to or exceed? Express this expectation as if you have full confidence that they can live up to it. Better yet, act like you assume they already are meeting these standards.
