For Jocko Willink, becoming a Navy SEAL was just like any other career. Willink was the commander of SEAL Team 3, Task Unit Bruiser. It was the most highly decorated US special operations unit of the Iraq War — and the one where Chris Kyle, of “American Sniper,” served. Willink retired from the SEALs in 2010 and started a consulting company called Echelon Front, which he founded with another SEAL named Leif Babin. He and Babin co-wrote the bestselling book “Extreme Ownership” in 2014. He’s also got a hit podcast, a line of jiu jitsu products, and even two bestselling children’s books. Willink says that passing on leadership lessons, whether to executives or kids, is just a continuation of what he did in the SEALs.
