The Unfinished Leader: A School Leadership Framework for Growth and Development

The key element that sets the incredibly effective leader apart from everyone else is their commitment to never settle for less than the very best. This internal drive is what fuels the grind and what allows for the seemingly impossible to be done. This drive indicates one thing. It is a daily symbol of the leader's firm recognition that they are unfinished. It is the personification of never being satisfied. It is the commitment to drain every last ounce of talent from our bodies while we have an opportunity to serve.
In The Unfinished Leader: A School Leadership Framework for Growth and Development, PJ, Nick, and Mike leverage decades of school and school system leadership and national and international leadership development and share the what, the how, and the why on the leader's journey. This book highlights the key characteristics of an effective leader: humble, vulnerable, courageous, open-minded, and inclusive and shows how these characteristics mixed with the mindset that personal development is never finished is necessary to achieve the lofty goals required to best support our kids and our communities.
This book asserts that leadership is not an event to be conquered and checked off of a list. Leadership is a journey, and the zenith of our individual journeys is never quite attainable as the very best among us continue to drive forward tirelessly to become better versions of themselves. This book is a guidepost to help leaders understand they are works in progress and to help create a vision for their individual futures.
