The greatest leaders combine the strengths and virtues of Principled Warrior and Authentic Wizard in that they "wield both sword and wand, know how to create as well as defend, accept reality but will challenge it because they see unfulfilled possibilities, learn by sensing and intuiting, are both strategists and visionaries, and combine the power of commander and the courage of a champion with the wisdom of the counselor and the magical powers of the shaman." But they are by no means perfect. However, as Bolman and Deal suggest (and I agree), we admire them because they somehow overcome their human weaknesses to achieve extraordinarily difficult goals. "As is clear from examples like Abraham Lincoln and Nelson Mandela, you need not like war to be a warrior." Bolman and Deal also point out that, the warrior heart "must be found in a cause important enough to justify the costs of combat. For many leaders, heart develops over time through experiences that test their courage and strength in the face of rigorous challenge and worthy competitors."
