Leadership is a much talked about and highly sought after thing. Yet, it is hard to quantify because it is part art and part science, and most situations that require it call for a mad scientist’s mixture of both. In this book, William J. Singleton covers some bedrock principles and insights concerning the essence of leadership that he has garnered in almost 50 years of life, 18 years of law enforcement work, and 27 years of service in the world’s premier and most highly leadership focused military fighting force. He also relates some fundamental truths about leadership and provides advice on how to execute it successfully.
