On May 21, 2014, Admiral William H. McRaven addressed the graduating class of the University of Texas at Austin on their commencement day. Taking inspiration from the university’s slogan, “What starts here changes the world,” he shared the ten principles he learned during Navy SEAL training that helped him overcome challenges not only in his training and long Naval career, but also throughout his life. Building on the core tenets laid out in his speech, McRaven now recounts tales from his own life and from those of people he encountered during his military service who dealt with hardship and made tough decisions with determination, compassion, honor, and courage.
