“There are no bad units, only bad officers. This captures the essence of what Extreme Ownership is all about.”

To not move around, observe, and analyze, in order to make the best decisions possible, was to fail as a leader and fail the team.

Calm but not robotic, logical but not devoid of emotions.

All animals, including humans, need to see the connection between action and consequence in order to learn or react appropriately.

In the SEAL Teams, the bond of our brotherhood is our strongest weapon. If you take that away from us, we lose our most important quality as a team.

A leader must lead but also be ready to follow. Sometimes, another member of the team—perhaps a subordinate or direct report—might be in a better position to develop a plan, make a decision, or lead through a specific situation.

The best leaders are not driven by ego or personal agendas.

Is this what I want to be? This? Is this all I’ve got—is this everything I can give? Is this going to be my life? Do I accept that?

The most fundamental and important truths at the heart of Extreme Ownership: there are no bad teams, only bad leaders.

Leadership isn’t one person leading a team. It is a group of leaders working together, up and down the chain of command, to lead.

Departments and groups within the team must break down silos, depend on each other and understand who depends on them.

We wrote this so that the leadership lessons can continue to impact teams beyond the battlefield in all leadership situations—any company, team, or organization in which a group of people strives to achieve a goal and accomplish a mission.

We learned that leadership requires belief in the mission and unyielding perseverance to achieve victory, particularly when doubters question whether victory is even possible.

If mistakes happen, effective leaders don’t place blame on others. They take ownership of the mistakes, determine what went wrong, develop solutions to correct those mistakes and prevent them from happening again as they move forward.

The U.S. Navy SEAL Teams were at the forefront of this leadership transformation, emerging from the triumphs and tragedies of war with a crystallized understanding of what it takes to succeed in the most challenging environments that combat presents.

Cover and Move, Simple, Prioritize and Execute, and Decentralized Command.

The most impressive thing about this improvement in performance was that it did not come from a major process change or an advance in technology. Instead, it came through a leadership principle that has been around for ages: Simple.
