Book excerpt: In this revelatory memoir, the former CEO of Sonic challenges established thinking, offering counterintuitive career advice essential for every professional at all levels, whether you're just starting out or in the middle of your career. In his bestselling Outliers, Malcolm Gladwell introduced readers to the 10,000-hour rule--the foundation of success in any endeavor. But as Clifford Hudson reveals, there are serious pitfalls to this rule. What happens to those who spend years trying to achieve something that doesn't quite pan out? Do you really have to grind down the same path for many years, sacrificing priorities to become successful? In this thought-provoking memoir, Hudson asks whether or not mastery is even necessary to succeed. Most people don't need to be experts in their field. Yes, the successful know more than the average person about a particular topic, and they often possess a better-than-average ability with a particular skillset; but not everyone who is successful is an expert, he makes clear. More importantly, in today's technology-driven environment, change is the only constant, including the nature of work and the skills required to do it. Over-investing in expertise is often riskier than learning to be adaptive and open to new knowledge, ideas, and skills. Experience can also lead to overconfidence. And yet we continue to deeply value the expertise ideal. In Master of None, Hudson turns expertise on its head and shows that by embracing variety and becoming more versatile, anyone can succeed and become more open to different opportunities in life. To do so, he provides three basic rule that will see any professional through: Don't plan, explore Don't specialize, generalize Don't keep your head down, turn it up toward opportunity Groundbreaking and thought provoking, Master of None is a new way forward to help businesses and professionals at all levels thrive.
