True vocational satisfaction follows mastery — not the other way around. This is the main point author Jordan Raynor makes in his new book. The bulk of Master of One describes a process to help readers choose their “one thing.” While he is quick to say there is not a “one size fits all” formula for work satisfaction, he does believe there is an effective method of selection he has seen in his life and the lives of others. The four steps in this process are: explore, choose, eliminate, and master. Mastering these are key to success in each season of work.
