In 1977, the author of Make Your Bed joined the Navy SEALS, beginning a career of encountering some of the world's most difficult problems firsthand—but also the best that mankind has to offer. In this inspiring homage to heroes he has known, retired admiral William McRaven salutes familiar figures like John McCain and Gary Sinise, but also Private Ashley White, veteran of Afghanistan; cancer researcher James Alison; and astronaut Charles Duke, the youngest man to walk on the moon. Along the way, McRaven stresses the value of such traits as courage, humility, compassion, forgiveness, and humor.
