This book highlights luck as a key idea for business and society. The author provides insights from economics, sociology, political science, philosophy, and psychology to create a brief intellectual history of luck. In positioning luck as a key idea in management, the book analyzes various facets of fortune such as randomness, serendipity, and opportunity.
