If you want to change the world, start off by making your bed. In 2014, Admiral William H. McRaven addressed the graduating class of the University of Texas, in a video which has since been watched over 10 million times. He shared the 10 principles he had learned during his Navy Seal training that helped him overcome challenges not only in his long Naval career, but also throughout his life. He explained how anyone can use these basic lessons to change themselves - and the world - for the better . . . Building on these principles in this book, McRaven recounts tales from his own life and from people he encountered during his military service who dealt with hardship and made tough decisions with determination, compassion, honour, and courage. Told with great humility and optimism, this timeless book provides simple and universal wisdom, practical advice, and words of encouragement that will inspire readers to achieve.
