Jocko Willink (@jockowillink) is one of the scariest human beings imaginable. He is a lean 230 pounds. He is a Brazilian jiu-jitsu expert who used to tap out 20 Navy SEALs per workout. He is a legend in the Special Operations world. His eyes look through you more than at you. He rarely does interviews, if ever. But a few weeks ago, Jocko ended up staying at my house and we had a caffeinated mind meld. Here's some background... Jocko enlisted in the Navy after high school and spent 20 years in the SEAL Teams, first as an enlisted SEAL operator and then as a SEAL officer. During his second tour in Iraq, he led SEAL Task Unit Bruiser in the Battle of Ramadi--some of the toughest and sustained combat in the SEAL Teams since Vietnam. Under his leadership, Task Unit Bruiser became the most highly decorated Special Operations Unit of the entire war in Iraq and helped bring stability to Ramadi. Jocko was awarded the Bronze Star and a Silver Star. Upon returning to the United States, Jocko served as the Officer-in-Charge of training for all West Coast SEAL Teams, designing and implementing some of the most challenging and realistic combat training in the world. So why is Jocko opening up? Well, in part, we have mutual friends. Second, he is the co-author of an incredible new book — Extreme Ownership: How U.S. Navy SEALs Lead and Win -- which I've been loving. Trust me. Buy it. This is his first mainstream interview and one you won't want to miss. Show notes and links for this episode can be found at www.fourhourworkweek.com/podcast.
