Extreme Ownership by Jocko Willink and Leif Babin is a leadership book that uses firsthand accounts from their time as Navy SEALs in the Iraq War to teach the principle of “extreme ownership”—taking full responsibility for your actions and outcomes. The book applies these military-honed leadership lessons to business and life, showing how taking accountability can lead to greater success, accountability, and teamwork in any organization. It emphasizes that true leaders don’t blame others but instead take ownership of all problems and work to solve them.
