Since his departure from Sonic Corp. in early 2019, Cliff has been sharing his philosophy on becoming a “Master of None”. In February 2019, he was the James R. Wilson annual guest lecturer at The College of Wooster where he unveiled plans to release a book on the topic. Over the last two years, he has been working on this, his first book, entitled Master of None - How a Jack-of-All-Trades Can Still Reach the Top. This personal story of his lifelong development of leadership skills challenges established thinking, offering counter-intuitive career advice essential to professionals at all levels, for the person just starting out or in the middle of their career. Publishing houseHarperCollins is set to release Master of None in October 2020. Master of None offers a different way forward, to help businesses and professionals thrive at all levels. One key take-away is that it’s okay to embrace life as a master of none, being comfortable with potentiality and variety, allowing yourself to thrive in unfamiliar environments, and seizing opportunities that you didn’t see coming. Above all, Master of None calls the reader to appreciate that flexibility and adaptation is the foundation for success in work and in life.
