Jeff Olson’s The Slight Edge is a self-help book about how to build consistent, positive habits that accumulate into greater successes and provide the foundation for a more fulfilling life. He defines the concept of “the slight edge” as little decisions that accumulate over time and explains how that can work for and against a person to help them achieve their dreams. He contextualizes his work within the greater body of self-help books and offers many anecdotes about his life and others to support his ideas.

The first part of the book establishes Olson’s credibility and details the concept and components of the slight edge. He opens with a story about two boys, the “beach bum” and millionaire, who grew up in identical circumstances with identical talent. One of them, however, ends up as a manual laborer on golf courses in Florida, and the other is a successful businessman. This hook raises a number of questions, like: How could two people grow up in identical circumstances? How is this possible? Olson reveals he is both of these people. At one point in his life he was a “beach bum,” and now, he is a millionaire. He extends this analogy to others, claiming that every person has the choice to follow one of these paths, and it has nothing to do with hard work or talent. It has everything to do with the slight edge. Olson walks through the steps that usually occur before people decide to implement the slight edge, including the day of disgust when a person cannot stand the way their life is going anymore and the choice that a person faces in these pivotal moments.

To illustrate his point, Olson shares a fable about two boys who are offered the choice to take a million dollars or a single penny that will double every day. The boys have one night to consider their options. One boy goes to sleep, and the other reads a collection of stories. The stories are fables that convey the importance of steady progress and continual effort. The boy who went to sleep decides to take the million dollars and hires a team of experts to help him manage his money and make wise investments. The other boy opts for the penny that doubles. By the end, the boy who took the million dollars lost all his money, and the boy who took the penny has a million dollars. This fable serves as a touchstone throughout the book for the idea of compounding interest, which is the continual return on consistent effort.

After exploring the impetus for transformation and providing this analogy, Olson explores various facets of the slight edge, such as how it works and how it fits into the existing frameworks of self-help and self-transformation. The slight edge is the product of positive philosophy, clear goals, a belief in the ability to achieve those goals, and a series of consistent, steady habits that can yield greater results over time. After building this definition and practice, Olson dispels the myth of the “quantum leap,” the belief that success happens overnight. He resists this notion and finds it toxic to growth because he believes that most meaningful, lasting change occurs through a series of small, daily decisions. These small decisions are easy to make, and therefore, they’re also easy to skip. When someone commits to making these little decisions but they don’t see the results they want immediately, they might think their efforts don’t matter and fall out of the habit of making good choices. Olson spends an entire chapter dismantling the myths perpetuated by American work and pop culture to show that true progress is slow and steady.

As people grow and become effective at using the slight edge, they can have a positive impact on others, which Olson demonstrates by turning over a chapter to his daughter. She describes the powerful ripple effect her father’s ideas had on her life and how she, in turn, uses what she’s learned to have a ripple effect on others. One’s slight edge can positively or negatively affect others based on one’s philosophy; negative energy will have a negative impact on people, and vice versa. Olson ends this section reminding readers that they don’t have to start with a lot to begin, but they do have to start with something small, a kernel of something, like just a single penny.

The second part of the book offers practical applications of the slight edge and sets the audience up to continue implementing what they’ve learned long after reading. Olson paints a picture of two divergent lives in a single moment: The decision to read a book or the decision to sleep, a small choice that reveals a lot about a person’s commitment to their goals. He offers some practical strategies and habits for mastering the slight edge, like establishing a plan to get started, journaling or logging progress, and celebrating the victories along the way. He suggests readers invest in themselves by taking classes, attending seminars, reading helpful books, finding an accountability buddy, and/or working with a coach. He also stresses the importance of finding a mentor: not a celebrity to hero worship but someone from whom a person can learn to improve a specific domain of their life. He shares a story about his own mentor, the manager of the Albuquerque Airport, who helped him on his career path and set his journey in motion without Olson even realizing it at the time. He reminds readers of the strategies and habits that can work in their favor, provides a list of interactive steps for the reader to complete, and ends with the idea that the reader has everything they need to implement the slight edge to their benefit in their lives.
