Don’t Be a One - Dimensional Leader! To be an effective leader you need to know your strengths - but that’s only part of the story. You also need a broad perspective on all the behaviors needed to be an effective leader. This book provides both. Using the third - generation DiSC online personality assessment - one of the most scientifically validated tools available - The 8 Dimensions of Leadership helps you identify your primary leadership dimension. Whether you are a Pioneering, Energizing, Affirming, Inclusive, Humble, Deliberate, Resolute, or Commanding leader, the authors help you understand the psychological drivers, motivations, and blind spots characteristic of your style. But no single style will take you all the way. A Humble leader may have a hard time making tough decisions. A Commanding leader may run roughshod over potential allies. The authors detail the lessons all leaders can learn from each style, enabling you to craft a multidimensional approach to becoming the leader you aspire to be.
