Si quieres cambiar el mundo, comienza por tender tu cama.  Si tiendes tu cama al despertar, habrás cumplido con tu primera tarea. Tendrás una sensación de orgullo y te alentará a cumplir un objetivo más, después otro y otro. Esa pequeña labor se convertirá en muchas metas cumplidas.  El autor, quien se sobrepuso a difíciles retos y se recuperó de un grave accidente de paracaídas, nos cuenta las profundas lecciones de vida —valorar la compañía, aceptar que el mundo no es justo, afrontar el fracaso, no darse por vencido y tender la cama— que aprendió durante uno de los entrenamientos físicos más desafiantes del mundo. ¡Los logros más trascendentes están hechos de pequeños pasos! ENGLISH DESCRIPTION Based on a Navy SEAL's inspiring graduation speech, this #1  New York Times  bestseller of powerful life lessons "should be read by every leader in America." --  Wall Street Journal. If you want to change the world, start off by making your bed. On May 17, 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; and he explained how anyone can use these basic lessons to change themselves-and the world-for the better. Admiral McRaven's original speech went viral with over 10 million views. 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. Told with great humility and optimism, this timeless book provides simple wisdom, practical advice, and words of encouragement that will inspire readers to achieve more, even in life's darkest moments.
