Principles of Extreme Ownership

1. Extreme Ownership (p. 29) On any team, in any organization, all responsibility for success and failure rests with the leader. The leader must own everything in his or her world. There is no one else to blame. The leader must acknowledge mistakes and admit failures, take ownership of them, and develop a plan to win. [...] This concept is the number-one characteristic of any high-performance winning team, in any military unit, organization, sports team or business team in any industry. 2. No Bad Teams, Only Bad Leaders (p. 53) When leaders [drive] their teams to achieve a higher standard of performance, they must recognize that when it comes to standards, as a leader, it’s not what you preach, it’s what you tolerate. When setting expectations, no matter what has been said or written, if substandard performance is accepted and no one is held accountable—if there are no consequences—that poor performance becomes the new standard. Therefore, leaders must enforce standards. Consequences for failing need not be immediately severe, but leaders must ensure that tasks are repeated until the higher expected standard is achieved.
