The hero code : what it takes to rise to the occasion
(Book)

When Bill McRaven was a young boy growing up in Texas, he dreamed of being a superhero. He longed to put on a cape and use his superpowers to save the earth from destruction. But as he grew older and traveled the world, he found real heroes everywhere he went -- and none of them had superpowers. None of them wore capes or cowls. But they all possessed qualities that gave them the power to help others, to make a difference, to save the world: courage, both physical and moral; humility; a willingness to sacrifice; and a deep sense of integrity.
