Extreme Ownership is a leadership book co-written by Jocko Willink and Leif Babin, two former Navy SEALs who led SEAL Team Three during the Iraq War. The book argues that the best leaders take extreme ownership, which means accepting responsibility for everything that happens in their teams or organizations.

The book is divided into three parts:

• The Dichotomy of Leadership: This part of the book discusses balancing humility and ego and leading from the front.
• Extreme Ownership: This part of the book discusses the importance of taking responsibility for everything in your team or organization and never blaming others.
• The Leadership Mindset: This part of the book discusses the importance of having a positive mindset and never giving up.

Here are some of the key takeaways from the book:

• Take responsibility for everything that happens in your team or organization.
• Never blame others.
• Lead from the front.
• Have a positive mindset.
• Never give up.
