Perhaps the most essential element of this text hinges on the ability to convert a nonbeliever into a believer—in the case of this book, turning someone who isn’t a One Minute Manager into a New One Minute Manager. This process requires any newcomer letting go of their notions of what they previously believed about leadership and adopting a new set of beliefs that will be beneficial to their future growth. Because the young man is seeking knowledge in the field of business and leadership, he has already taken the first step towards conversion by opening himself up to the possibilities of a better way of operating. The process requires him to be inquisitive, but his skepticism prevents him from diving into new rules of leadership from the onset. He doubts and questions the truth. Over the course of the text, the young man’s journey leads him to embrace the Manager’s secrets and principles. This process of conversion makes him a believer.

The mantras used by the Manager and his employees are one of the many elements used to create this belief. Whenever the young man is unsure or needs clarification, they reveal a mantra that guides him in understanding their belief system.
