Can’t Hurt Me by David Goggins is a powerful memoir and self-help book that chronicles the author’s journey from a troubled childhood to becoming a Navy SEAL and ultra-endurance athlete. The book offers insights into mental toughness, overcoming obstacles, and pushing beyond limits. Published in 2018, this book has inspired many to master their mind and defy the odds. It serves as both a memoir and a guide to building mental resilience, making it a popular read for those looking to overcome personal challenges and reach their full potential.
One of the most prominent literary devices used throughout Can’t Hurt Me is metaphor. Goggins frequently employs metaphorical language to convey abstract ideas about mental toughness, resilience, and personal growth. These metaphors make complex psychological concepts more relatable and vivid for readers.
“Callousing the mind”: This metaphor is central to Goggins’ philosophy of mental toughness. He compares the mind to the hands of someone who works with physical tools, where repeated exposure to pain (in this case, hardship) creates “callouses” that make it stronger and more resistant to future challenges. The imagery of “callousing” helps readers visualize how the mind can be trained to endure and overcome adversity. It shifts the idea of mental toughness from something abstract to something tangible, emphasizing that, just like hands toughened through hard work, the mind also becomes stronger with repeated exposure to difficulty.
“Taking souls”: Goggins uses this metaphor to describe the act of mentally overpowering an opponent by showing resilience when they expect you to give up. While “taking souls” sounds aggressive, in Goggins’ use, it’s about psychological domination. It’s the moment when you outlast your competition to such a degree that they lose morale, giving you a mental edge. The metaphor evokes images of seizing the inner strength or spirit of an adversary, transforming a physical challenge into a psychological one.
“The 40% rule”: This metaphor symbolizes the idea that most people are operating far below their potential, typically only using 40% of what they’re capable of. The “40% rule” encapsulates Goggins’ belief that there is far more within each person than they realize, and this simple, measurable metaphor makes the concept of untapped potential clear and actionable. It provides a concrete framework for readers to assess their own limitations and understand that they can push further than they believe.
Goggins’ metaphors—like “callousing the mind” and “taking souls”—create vivid, memorable images that make complex ideas about mental strength accessible and relatable. These metaphors serve as powerful tools for conveying Goggins’ key messages about resilience and pushing beyond limits.
Repetition is a literary device Goggins uses to emphasize key concepts and instill them in the reader’s mind. Throughout the book, he reiterates core themes such as accountability, mental toughness, and the importance of pushing beyond perceived limits.
“Own your truth”: Goggins repeatedly stresses the importance of personal accountability and owning one’s actions, circumstances, and failures. By frequently revisiting this idea, he reinforces its significance in personal growth. The repetition of phrases like “own your truth” serves to remind readers that transformation begins with taking full responsibility for where they are in life.
“Stay hard”: This phrase is repeated multiple times throughout the book, both as a motivational mantra and a reminder of the mental toughness Goggins advocates. By continuously urging readers to “stay hard,” Goggins drills the concept of resilience and the necessity of maintaining a strong mindset through repeated challenges.
Challenges: Goggins often revisits the concept of setting and embracing challenges as a means of self-improvement. Throughout the book, each challenge builds on the previous one, with repetition serving to reinforce the idea that growth comes from consistently facing and overcoming adversity.
Goggins uses repetition as a literary device to emphasize key ideas such as accountability and mental resilience. By repeatedly reinforcing these concepts, he ensures that they resonate with readers and become ingrained in their thought processes.
Vivid imagery is another device Goggins uses to make his experiences come alive for readers. His descriptions of physical pain, mental anguish, and the process of overcoming these hardships are powerful, making the reader feel as though they are experiencing these challenges alongside him.
Physical endurance: Goggins uses strong, sensory imagery to describe the pain and exhaustion he endures during ultra-marathons, Navy SEAL training, and other grueling physical tasks. His detailed accounts of running on broken legs, enduring Hell Week, and pushing past physical exhaustion paint a visceral picture of suffering and determination. This imagery not only illustrates the physical toll but also serves as a metaphor for the mental strength required to endure such challenges.
Emotional trauma: Goggins also uses imagery to describe the emotional scars from his abusive childhood. The mental image of a young boy working late hours at his father’s roller rink, enduring violence and fear, creates a powerful emotional connection with the reader. These descriptions make the reader feel the weight of Goggins’ struggles and emphasize the depth of the adversity he had to overcome.
Transformation: The imagery of Goggins’ physical transformation—from an overweight, unmotivated man to an elite Navy SEAL and ultra-endurance athlete—is vivid and symbolic of his broader mental transformation. By painting a clear picture of this drastic change, Goggins makes his journey relatable and inspirational, showing readers that no matter how far gone they may feel, transformation is possible.
Through vivid imagery, Goggins makes his physical and emotional challenges tangible for readers, helping them understand the depth of his suffering and the strength required to overcome it.

Goggins occasionally uses allusions to connect his personal journey to broader themes of hardship, resilience, and self-mastery. These allusions often reference historical events, military traditions, or cultural beliefs, adding a layer of depth to his story.

Symbolism is used sparingly but effectively in Can’t Hurt Me, with certain experiences or objects representing broader concepts of personal growth, resilience, or struggle.
The “Accountability Mirror”: One of the most significant symbols in the book is the “Accountability Mirror,” a literal mirror Goggins used to confront his failures and shortcomings. This mirror symbolizes self-reflection and radical honesty. By writing goals and challenges on Post-it notes and sticking them to the mirror, Goggins created a physical representation of his accountability. The mirror becomes a powerful symbol of self-awareness and the drive to improve.
The pull-up bar: Another potent symbol is the pull-up bar, representing Goggins’ physical and mental endurance. When he broke the world record for most pull-ups in 24 hours, the bar became a metaphor for persistence, struggle, and triumph. It symbolizes Goggins’ belief in pushing beyond perceived limits and achieving greatness through hard work and repetition.
Symbolism in Can’t Hurt Me—such as the “Accountability Mirror” and the pull-up bar—adds layers of meaning to Goggins’ journey, representing deeper concepts of self-reflection and perseverance. These symbols help readers understand the broader implications of Goggins’ lessons.
