Sir Richard Branson, the world-famous entrepreneur, eccentric, and billionaire rebel, has created a huge number of completely different businesses united under the Virgin brand. In his new book, with characteristic candor and humor, he shares his principles and rules of life that allowed a troubled teenager—who dropped out at 16—to found dozens of successful companies. Richard Branson’s rules help him live at full power and achieve phenomenal success in business over decades, without feeling tired and without losing his spark when tackling difficult challenges.
