In this episode, I chat with Commander William C. Spears. William is a submarine warfare officer in the United States Navy, and author of the upcoming book Stoicism as a Warrior Philosophy. He enlisted in the Navy in June 2001, then earned his commission through the United States Naval Academy in Annapolis. He has since led a career in nuclear submarines, where he was most recently the second-in-command of a ballistic missile submarine. Today he works at the Pentagon in Washington, D.C.
