As the title of the book suggests, the concept of “one more” is applied to nearly every facet of The Power of One More. All the topics discussed—lifestyle, mentality, discipline, lessons, dreams, goals—revolve around pushing oneself to give an additional effort. In some sections, Mylett uses one more as an adjective to describe different actions and identities, such as a one more thinker, leader, and multiplier. In other moments, Mylett uses the noun “one mores” to indicate the efforts, people, and actions to generate success.

In addition to its universal importance to the argument, the one more mindset can be divided into two parts: the theoretical and the practical. “The Power of One More,” writes Mylett, “is about thinking and doing” (100). Theoretical and practical applications of the one more mindset work together to enhance productivity, increase self-worth, and achieve goals. The oscillation between thinking one more and doing one more is the strategy Mylett wants to impart to readers.

Mylett also turns the one more mindset into an identity: the one more thinker, leader, achiever, and multiplier. Although not stated explicitly, it is implied that any individual can embody all these identities if they follow Mylett’s advice.
