I strongly recommend this book by Liz Wiseman and Greg McKeown (see http://multipliersbook.com/), which outlines the the 5 key behaviours of great leaders who are able to get the maximum out of their people (called "Multipliers"). The book contrasts the Multipliers with the Diminishers, who seem to reduce the capabilitry of their organisations through their behaviours.
A Multipler is a leader who is able to extract so maximum value and performance from their direct reports, colleagues and coworkers while a Diminisher is a leader who tends to suck the energy, excitement and passion out of their direct reports and coworkers. Multipliers enhance the abilities of others while diminishers degrade the abilities of others. My guess is that Mike Auzenne was a Multiplier throughout his leadership career (no disrepect to you Mark, but we don't hear much about your leadership style).
While there may be nothing new in this book, they way the authors bring together the concepts into a clear and coherent framework made it so easy for me to see the big picture. Consistent with the Manager Tools way, it is not just a theoretical treatise, but contains actionable advice.
As a reforming Diminisher, who is passionate about getting more out of people, this book really spoke to me.
