Extreme Ownership is a non-fiction book written by ex-Navy Seal operators Jocko Willink and Leif Babin that both educates and entertains. In each chapter, the writers describe real accounts of their military experiences highlighting key aspects of leadership principles, then they lay out the principles involved in a more abstract way and then illustrate the application of the principles to the business world using real-life examples from their work with high-level leaders in the corporate world. Each chapter highlights a specific leadership trait or strategy such as extreme ownership, decentralized command, cover and move, check the ego, leading up and down the chain of command and much more.
