In his late 40s, American writer George Leonard took up the practice of aikido (modern Japanese martial art) and he went on to earn a a fifth-degree black belt. In Mastery: The Keys to Success and Long-Term Fulfillment, Leonard draws up his expertise in aikido and Zen philosophy to describe the process of mastery. He identified the five keys to mastery as instruction, practice, surrender, intentionality and the edge.
The book is based on Leonard’s 1987 Esquire Ultimate Fitness special, MASTERY: TAKING IT HOME – Its principles can be applied to anything in life that involves learning—even love. The subject of the special was mastery “the mysterious process during which what is at first difficult becomes progressively easier and more pleasurable through practice.” The purpose of the feature was to describe the path that best led to mastery, not just in sports but in all of life, and to warn against the prevailing bottom-line mentality that puts quick, easy results ahead of long-term dedication to the journey itself.”
