Summary: Can’t Hurt Me

The GIST

Can’t Hurt Me by David Goggins is half memoir, half boot camp. Its subtitle is Master Your Mind and Defy the Odds, and the life it describes earns the phrase. Goggins grew up in a violent home, was bullied for his race, could barely read, ballooned to nearly 300 pounds in his twenties, and then remade himself into a Navy SEAL, a graduate of Army Ranger School, a finisher of more than sixty ultramarathons, triathlons and ultra-triathlons, and a Guinness World Record holder for pull-ups. Written with Adam Skolnick, the book walks through that transformation in eleven chapters, and closes each one with a challenge for the reader.

Its argument is blunt. Most of what holds us back is in our heads, and the mind can be trained like a muscle, by deliberately choosing hard things. Goggins is not offering motivation, which he dismisses as kindling that burns out on the first bad day. He wants obsession. And he does not want to be admired. He wants readers to face their own excuses and become, in his phrase, uncommon in their own world. As he puts it, "The most important conversations you’ll ever have are the ones you’ll have with yourself."

The Big Ideas

Own the story you were handed

The opening chapter is titled I Should Have Been a Statistic, and Goggins means it. Born in Buffalo, New York, in 1975, he lived in constant fear of a father whose rage ruled the household. After he and his mother got away, the trouble followed in other forms. He was the only Black child in his school and a target for racism. He struggled with dyslexia, attention problems and the toxic stress of everything he had lived through, and he got by in class by cheating. He was angry, and he felt helpless.

Goggins tells all this without asking for pity, because the first idea of the book is that your worst material can become your best fuel. "When you’re driven, whatever is in front of you, whether it’s racism, sexism, injuries, divorce, depression, obesity, tragedy, or poverty, becomes fuel for your metamorphosis." The first challenge is to write it all down: the things that limit you, the long odds, everything that has hurt you. You cannot use what you refuse to look at.

Looking is the job of the Accountability Mirror. Goggins stood in front of a bathroom mirror and told himself the truth, with no cushioning, about who he was and what he was failing to do. Then he stuck notes on the glass naming his insecurities, his goals and each small step needed to reach them, so that he had to face them every day. He says it is fine to be hard on yourself so long as the purpose is to get better. Stop blaming other people, he learned, and you get your power back.

Callous your mind

The first dream was to become an Air Force pararescueman, after he heard the story of Scott Gearen, a pararescueman who survived a catastrophic fall. Goggins, who read at about a third-grade level, taught himself to read well enough to pass the entrance test. Then he hit the pool. Terrified of being held underwater, he floundered in water confidence training, and when a medical diagnosis offered him a way out, he took it. He served in a different Air Force role, but he knew he had quit, and the knowledge ate at him. Out of the service he drifted, stopped training, binged on food, and reached about 300 pounds and the edge of diabetes.

One night a documentary about the Navy SEALs lit something in him. He was far too heavy even to be admitted to training, and he badgered recruiters until one gave him a chance. He had only a few months to lose around a hundred pounds and pass the entrance exam again. He did both.

From this comes the book's central image. Hands that do hard work grow calluses. Minds do too. If you expose yourself to discomfort on purpose, again and again, the discomfort loses its grip: "You’ll feel pain, but if you accept it, endure it, and callous your mind, you’ll reach a point where not even pain can hurt you." Comfort, by contrast, becomes a trap if you stay in it long enough for it to be your normal. Goggins recommends doing something that you hate every single day. For him it was swimming, since he sinks like a stone. This is not self-punishment. The point is that when life delivers real hardship, as it did when he learned he needed heart surgery, you already know how to meet it.

Take souls, and armor the mind

SEAL selection is built around Hell Week, and Goggins went through it three times, pushing on through double pneumonia and fractured kneecaps along the way. There he worked out a tactic he calls taking souls. When someone is trying to break you, the answer is to perform so far beyond what they expect that they are the ones left demoralized. You leapfrog their opinion of you. The civilian version is the fourth challenge: pick the boss, teacher or difficult client who underrates you, and respond with excellence, meeting every standard they set and then beating it.

The chapter called Armored Mind adds visualization. Picture the goal achieved, but also picture the obstacles that are bound to arise and decide in advance how you will attack them. And know your reasons. "Know why you’re in the fight to stay in the fight!" A person who cannot answer why he is suffering will stop when it gets bad enough.

The Cookie Jar and the 40% Rule

As a SEAL, Goggins took up ultra-distance running, partly to raise money for charity. He threw himself into 100-mile races with no background in the sport, went on to finish Badwater 135, known as the toughest ultramarathon in the world, and competed in Ironman triathlons. These races taught him the two tools most readers remember.

The Cookie Jar is a mental store of everything you have already survived and achieved, including the things you failed at first and then conquered on a second or third try. When pain arrives and tells you to stop, you reach in, pull one out, and remind yourself who you are at your best. Life will not pick you up when you fall, he says, so you need a system that does.

The 40% Rule holds that when your mind announces you are finished, you have used roughly 40 percent of what you have. He compares the brain to an engine fitted with a governor, a device that caps speed well below what the machine can do. That first wave of pain and fatigue is the governor talking. Nobody gets access to the remaining 60 percent in one go, and the figure is better taken as a rule of thumb than a measurement; the method is to reach the point where you badly want to quit and then go 5 to 10 percent further, raising the baseline week by week so that body and mind adapt without injury.

Along with the tools comes a list of things to stop complaining about. You will be mocked. You will feel insecure. You will sometimes be the only person like you in the room. You will feel alone. Accept it and move on.

Talent not required

Goggins credits his achievements to work ethic above everything else. He has no patience for life hacks and shortcuts, which he says may win you a few trophies but never self-mastery. A forty-hour week, in his view, is a 40 percent effort. There are 168 hours in a week, and most people waste four or five hours of every day.

His remedy is to run your life like a mission: audit your time, cut the empty habits, give each hour a priority, and do one thing at a time with complete focus, since multitasking makes a person mediocre at many things. He is not arguing against rest. Sleep, short naps and one full day off a week, with the phone switched off, belong on the schedule too.

This is also where he asks what it means to be uncommon amongst uncommon. Reaching an elite group is not the finish line; SEALs can coast too. Greatness has to be sustained, earned again every day. He is honest that his own pursuit of it made him arrogant and confrontational for a time and cut him off from his teammates. And he is clear that the idea is not limited to soldiers and athletes. The uncommon person is the one still at the office at midnight, the firefighter sharpening her chainsaw after a twenty-four-hour shift, or the traveller who comes home exhausted to a filthy house and cleans it instead of blaming someone.

The empowerment of failure

When health problems forced him to stop running, Goggins chose a new target: the world record for pull-ups in twenty-four hours. It took repeated, painful attempts before he broke it in 2013 with 4,030 in seventeen hours. He treats those failed attempts as the most useful part of the story. "In life, there is no gift as overlooked or inevitable as failure." Each one showed him what to fix. His closing thought is that the work is never done, and that the question to keep asking is what if: what if you could do more than you have ever believed?

Putting It to Work

• Write your inventory. List what limits you and what has hurt you. That list is your fuel.
• Build an Accountability Mirror. Put your goals, your insecurities and each next step on notes where you will see them daily, and be honest about where you stand.
• Do one uncomfortable thing a day, especially something you know is good for you. Then do it again.
• Answer doubters with excellence. Exceed the standard set by whoever underrates you.
• Visualize the obstacles as well as the win, and know why you are doing it.
• Stock your Cookie Jar. Write down past victories and reach for them when you want to quit.
• Push the governor back gradually. When you want to stop, go 5 to 10 percent further, and build from there.
• Schedule your life. Track a week with timestamps, design a better week in blocks of fifteen to thirty minutes, refine it in the third, and protect your rest.
• Do not copy his stunts. Goggins warns readers against attempting what he did without preparation. Extremes took a real toll on his body. Raise your own bar step by step.

Who Should Read It

This book is for anyone stuck in a comfort zone, anyone who feels written off because of where they started, and athletes or service members who want a jolt. It reads more as a gripping life story than a tactical manual, and it is intense, repetitive in places and full of profanity, though a clean edition exists. Some readers find Goggins a little too impressed with himself. The audiobook, in which Skolnick narrates and pauses to talk things over with Goggins, is widely recommended. If you want the plain message that you are capable of far more than you think, delivered at full volume, this is it.
