It features a diverse collection of leaders, all of whom have personally wrestled with the “vert” matrix during their lives and careers. These leaders have shared their perspectives as part of Moore’s research for this Work, which enables readers to expand their own understanding of how effective leadership can be exercised. My review brought to mind two excerpts from the works of William Shakespeare that focus on the phenomenon of role-playing and how personal values remain a foundational element of genuine leadership. The first is from As You Like It:All the world’s a stage,And all the men and women merely players.They have their exits and their entrances;And one man in his time plays many parts. The second is from Hamlet, as part of the advice given by Polonius to his son Laertes:This above all: to thine own self be true.And it must follow, as the night the day,Thou canst not then be false to any man.On occasion, leaders must be prepared to act, seemingly out of character (even in roles with which they may be uncomfortable), but while harnessing those role-playing tactics, never compromise their values.Richard Pound, Olympic Athlete and Olympic Committee (IOC) Member for over 40 yearsKudos to Karl Moore! In today’s complex environment, good leadership rests on a constant exploration of oneself to ensure that who we are, what we stand for, and how we relate to our work are in harmony, if we want to successfully build strong teams. Karl’s thoughtful book offers valuable insights to all leaders in our lifelong endeavour of self-discovery and growth. Bravo Zulu!General Jennie Carignan, Chief of the Defence Staff, Canada
