Book summary “13 Things Mentally Strong People Don't Do”: summary

Introduction

Building physical strength requires you to exercise and eat well while eliminating junk food from your diet. Mental strength works the same way. You can practice all the optimism you want, but destructive habits will still hold you back.

Amy Morin learned this truth through profound personal loss after losing both her mother and her husband at a young age. Years later, as a psychotherapist, she needed a reminder of these principles and wrote a viral article about mental habits. That list resonated with millions of readers and became this book.

Building true mental strength requires eliminating the self-destructive habits, negative thoughts, and emotional pitfalls that hold you back.

The book explores how your thoughts, behaviors, and emotions intersect. You will discover answers to specific questions about your daily struggles:

• How do you stop giving away your personal power?
• Why do you repeat past mistakes?
• How do you stop comparing your success to the success of others?

1. Taking Back Your Power and Stopping Self-Pity

You must stop wasting energy on self-pity and giving away your personal power to external circumstances and other people.

They Don't Waste Time Feeling Sorry for Themselves

Self-pity acts as a defense mechanism to avoid real fears, delay responsibility, and gain initial sympathy or attention. However, it spirals into negative emotions, acts as a self-fulfilling prophecy, and blinds individuals to the positive aspects of life.

Jack's parents kept him home after a school bus accident and pitied him, which only increased his sadness and isolation until a therapist helped him reframe the event as surviving a fight with a school bus.

You can break this cycle by adopting specific countermeasures:

• Give yourself a reality check so you don't exaggerate how bad the situation really is
• Replacing overly negative thoughts about your situation with more realistic thoughts
• Choosing to actively problem-solve and work on improving your situation
• Getting active and behaving in a way that makes you less likely to feel sorry for yourself, even when you don't feel like it
• Practicing gratitude every day

They Don't Give Away Their Power

Allowing other people and external circumstances to control your thoughts, feelings, and behavior destroys mental strength. When you fail to set healthy physical and emotional boundaries, you become a victim of your circumstances. Complaining about difficult people or blaming them for your emotional state wastes your time, fuels your frustration, and keeps you dependent on others for your self-worth.

Lauren spent five hours a week physically interacting with her meddling mother-in-law Jackie, plus an additional five hours talking and thinking about her disdain for her.

Changing your language from victimhood statements to choice-based statements helps reclaim your personal power. You can apply these proactive steps:

• Use language that acknowledges your choice such as, 'I'm choosing to...'
• Setting healthy emotional and physical boundaries with people
• Behaving proactively by making conscious choices about how you'll respond to others

2. Embracing Change and Controlling the Uncontrollable

Mental strength requires welcoming necessary transitions and focusing exclusively on your own behavior rather than policing the world.

They Don't Shy Away from Change

People often avoid change due to grief over leaving things behind or fear of discomfort. Evaluating lists of pros and cons for both options helps balance emotional resistance with rational long-term benefits.

Successfully making a behavioral change requires progressing through five distinct psychological stages rather than relying purely on motivation.

• Precontemplation
• Contemplation
• Preparation
• Action
• Maintenance

Richard was 44 years old and 75 pounds overweight when diagnosed with diabetes. He went through these stages in therapy regarding his health, moving from denying his diabetes risk to preparing a schedule, taking action, and maintaining his routine by focusing on smaller 5 pound incremental goals.

The author categorizes change into six distinct types:

• All-or-nothing change
• Habit change
• Trying-something-new-change
• Behavioral change
• Emotional change
• Cognitive change

You do not need to wait until you feel like changing or until the right time arrives. You can start by acting like the person you want to become right now.

You can apply these practical steps:

• Identify your goal for what you would like to accomplish in the next thirty days.
• Establish concrete behavior changes you can make to reach that goal each day.
• Anticipate obstacles along the way and make a plan for specific challenges.
• Establish accountability through friends, family, or writing down your progress daily.
• Monitor your progress by keeping a record of your efforts and daily achievements.

They Don't Focus on Things They Can't Control

A rigid belief that you can control everything leads to heightened anxiety and strained relationships, whereas a balanced bi-local perspective fosters resilience and happiness.

James spent years fighting a custody battle and trying to control his ex-wife's lifestyle choices and dating life. This backfired, wasted money, and damaged his relationship with his daughter.

Confronting deep fears head-on allows individuals to let go of attempts to control unmanageable outcomes. Heather Von St. James was diagnosed with mesothelioma at age 36 with a 15-month prognosis while her daughter was 3 years old. She commemorates Lung Leavin' Day every February 2 by writing her fears of cancer returning on a plate and smashing it into a fire.

Nagging, making threats, and trying to force others to change ruins relationships. Jenny dropped out of college to pursue art, prompting her mother to call daily with insults and threats, which ultimately caused Jenny to stop answering the phone and cut off contact.

You can use these strategies to manage control:

• Ask yourself what you are so afraid of when you notice yourself trying to control something you cannot.
• Acknowledge your fears and identify what is within your control versus what is outside of it.
• Focus your efforts exclusively on your own behavior and attitude.

3. Setting Boundaries and Taking Calculated Risks

You must abandon people-pleasing tendencies and replace emotional fear with rigorous strategic evaluation when taking risks.

They Don't Worry About Pleasing Everyone

People-pleasing is not a selfless act of kindness but a self-centered attempt to control how others perceive you while sacrificing your own values and immediate family. People pleasers assume everyone cares about their actions and that they can control other people's emotional reactions. This behavior leads to physical and emotional exhaustion, resentment, and a total loss of authentic self-expression.

Megan was a thirty-five-year-old wife and mother who could never say no to extended family members or church tasks, which meant she was constantly saying no to her husband and children.

To break the habit of automatically agreeing to requests, you must pause, buy time, and evaluate the true personal cost of saying yes. By forcing a delay before answering, you prevent automatic compliance and allow your logical mind to assess whether the favor aligns with your genuine desires and priorities. Megan used a standard script to buy time by telling requesters she needed to check her schedule and get back to them.

Living a life aligned with your personal values requires explicitly ranking them so you do not misallocate your finite time and energy. People often fail to live authentically because they never define their core values. Without a clear hierarchy of what truly matters, they defer to pleasing others or chasing societal expectations.

A working single mother left her ten-year-old sick son home alone because her values dictated that keeping her job was necessary for the greater long-term good of her family, despite potential social judgment.

Refusing to pander to critics and market pressures allows leaders to stay intensely focused on serving their core audience and fulfilling their true purpose. When companies or individuals stop worrying about pleasing everyone, they gain the resilience to maintain unconventional business models that ensure long-term survival and massive valuation. Jim Buckmaster became CEO of Craigslist in 2000 and resisted massive revenue-generating advertising opportunities, earning fierce criticism and labels like social anarchist, but kept the site free and focused, building an enterprise estimated to be worth at least 5 billion dollars.

They Don't Fear Taking Calculated Risks

Risk aversion is primarily driven by ungrounded emotional anxiety rather than statistical reality, leading people to avoid necessary growth. Humans frequently mistake their internal level of fear for the actual magnitude of a risk. When emotions dictate decisions, people rely on flawed heuristics such as overestimating control, letting superstition guide choices, or letting temporary stress distort rational judgment. Consider that statistical odds of dying in a car crash are 1 in 5,000, while the odds of dying in a plane crash are 1 in 11 million. On average, 10,000 fewer people fly on Friday the thirteenth.

Dale was a high school shop teacher who dreamed of opening a furniture store but stayed paralyzed by past financial losses until he learned to lower his startup risk by launching part-time on nights and weekends.

Systematically exposing yourself to rejection helps extinguish the irrational fears that prevent you from taking social and personal risks. By deliberately engineering scenarios where failure or rejection is likely, you prove to your brain that you can tolerate uncomfortable emotions and survive negative social outcomes. Psychologist Albert Ellis, named the greatest living psychologist by Psychology Today in 2007 the year of his death, overcame his intense shyness and fear of women by sitting next to female strangers in a botanical garden every day for a month. He found 130 total opportunities to speak with women in one month, endured 30 women walking away immediately, and invited 100 women on a date.

Rigorous calculation of potential costs, benefits, and worst-case scenarios transforms a terrifying blind gamble into a manageable strategic judgment. Instead of reacting impulsively out of fear or excitement, individuals should systematically analyze alternatives, evaluate worst-case resilience, and measure long-term impact to determine if a risk is worth taking. Othmar Ammann left his secure role as chief engineer at the Port Authority at age 60 to design monumental American bridges like the Verrazano-Narrows, continuing his extraordinary career until age 86. Similarly, Richard Branson started his bird-breeding business at age 15, and his Virgin Group now owns 400 companies with an estimated net worth of 5 billion dollars.

Strategic judgments replace emotional fear when you systematically analyze alternatives and measure long-term impact.

4. Releasing the Past and Learning From Mistakes

Dwelling on past tragedies or repeating past mistakes stalls growth, demanding objective analysis and concrete recovery plans instead.

They Don't Dwell on the Past

Mentally strong people avoid dwelling on the past, as ruminating on past mistakes or tragedies prevents living fully in the present and planning for the future. Dwelling on the past through guilt, shame, or romanticizing old days clouds judgment, interferes with decision-making, and triggers physical inflammation. Acceptance of the past without self-punishment is essential to move forward.

A 2013 study by researchers at the University of Ohio showed that thinking constantly about negative events increases inflammation in your body.

Gloria was a fifty-five-year-old mother who felt extreme stress and enabled her unemployed adult daughter because of intense guilt over her past parenting mistakes. Once she forgave herself and set rules, her daughter got a career-track job. Attempting to keep things frozen in time after a loss keeps people stuck in grief and prevents new memories.

The author spent the six years that she and Lincoln were together building a life, then took two years to finally throw away his toothbrush. Grief often triggers irrational thoughts, leading people to cling to belongings as if they are clues to understanding a lost loved one. However, letting go of physical items does not mean abandoning memories.

Refusing to dwell on the past enables survivors of severe trauma to transform their pain into constructive action in the present. Accepting and embracing past experiences rather than pretending they did not happen frees up mental energy and allows individuals to break generational cycles of abuse.

Wynona Ward left home and got married at seventeen years of age, spent sixteen years of traveling the country as a truck driver, and went to law school before founding Have Justice Will Travel to provide free legal representation to rural domestic violence victims.

You can manage intrusive thoughts by using specific mental strategies:

• Schedule time to think about a past event by telling yourself you can think about it after dinner for twenty minutes
• Give yourself something else to think about by creating a plan to shift your focus
• Establish goals for the future to keep your mind occupied
• Focus on the lessons you learned from hard times
• Think about the facts and details of a memory rather than the distressing emotions

They Don't Make the Same Mistakes Over and Over

Mentally strong people do not make the same mistakes over and over; instead, they study their missteps and change their behavior. Repeating mistakes stems from stubbornness, impulsivity, pride, or fear of discomfort. Research shows that making errors and correcting them actually improves retention and learning, provided a person analyzes what went wrong.

A 2012 research study published in the Journal of Experimental Psychology: Learning, Memory, and Cognition showed that people can learn from previous mistakes.

Kristy struggled with yelling at her teenagers every evening out of frustration until she developed alternative discipline strategies and a plan to manage her anger. Creating a concrete written plan is essential for avoiding repeated mistakes and breaking unhealthy lifestyle cycles. Without a structured plan, individuals easily slip back into old environments, bad social circles, and familiar temptations that cause relapses.

Patients at an inpatient drug and alcohol rehabilitation center needed a clear discharge plan involving lifestyle and social circle changes to maintain long-term sobriety. Failures and repeated business mistakes serve as foundational learning experiences for massive long-term success when approached with objective analysis. Famous entrepreneurs experienced multiple bankruptcies and failed ventures before applying the hard-earned lessons to build world-renowned enterprises.

In the mid-1800s, Rowland Macy opened his first dry goods store and suffered four failed dry goods store ventures before opening R.H. Macy Dry Goods in New York. Today, forty-four million viewers watch the Macy's Thanksgiving Day Parade on TV each year. Milton Hershey was nineteen years of age when he opened his first candy company, faced multiple bankruptcies, and sold his caramel company in 1900 to open a chocolate factory.

Increasing self-discipline requires constant vigilance, tolerating discomfort, and active mental strategies rather than relying on innate willpower. Giving in to temptation even once diminishes self-control. Maintaining progress requires positive affirmations, goal visualization, and self-imposed restrictions.

Julie lost and gained the same forty pounds over a decade because she repeatedly relaxed her discipline after initial success and fell back into old habits.

You can prevent repeated missteps by evaluating every error systematically:

• What went wrong by discerning the facts and contributors
• What could I have done better through an honest evaluation
• What can I do differently next time by identifying clear strategies

5. Avoiding Resentment, Solitude Phobia, and Entitlement

True mental toughness rejects envy of others, entitlement, and the fear of solitude, valuing cooperation, patience, and inner reflection.

They Don't Resent Other People's Success

Resentment goes beyond fleeting jealousy by wishing not only to have what others possess, but also wanting them not to have it. This toxic emotional trap functions as a distraction and prevents personal growth. It is fueled by perceived injustices, deep-rooted insecurities, stereotypes, and unrealistic comparisons.

Dan worked long hours and went deeply into debt to buy material goods to compete with his neighbors, hiding his financial struggles until therapy helped him align his life with his true values.

A 2013 study titled "Their Pain, Our Pleasure: Stereotype Content and Schadenfreude" analyzed brain activity and found that participants showed the most glee when a rich professional experienced minor problems, driven entirely by the stereotype that rich professionals are bad. A 2013 study titled "Envy on Facebook: A Hidden Threat to Users' Life Satisfaction" showed that seeing vacation photos or birthday wishes on social media generates negative emotions and an overall decline in general life satisfaction for vulnerable users.

Shifting from viewing people as direct competitors to cooperating with them allows you to build stronger networks and achieve mutual success. Milton Hershey supported his employee H. B. Reese when Reese started a competing candy company using Hershey's chocolate as a supplier, eventually leading to a corporate merger where Reese's peanut butter cups became immensely popular.

True contentment comes from defining personal success based on individual core values rather than chasing external societal markers like wealth. Recognizing that another person's success does not diminish your own potential allows you to feel genuine joy for milestone achievements without feeling threatened. Peter Bookman, founder of the company that became Fusion-io, left the startup before it became a billion-dollar business that earned founders $250 million, yet he harbors no resentment and happily celebrates their success.

They Don't Fear Alone Time

Modern society often views being alone negatively through associations like solitary confinement or loneliness, leading people to overbook calendars and stay constantly connected via technology. However, moderate alone time and solitude spark creativity, increase empathy, improve mental health, and offer restoration.

Vanessa, a busy real estate agent, suffered from racing thoughts and sleep problems because she never allowed her brain downtime. By scheduling ten minutes of journaling and practicing meditation, she calmed her mind and fell asleep faster.

Constant digital communication, checking phones, and scrolling through social media introduce interruptions that increase stress and anxiety. Tolerating silence and unplugging from technology allow you to process experiences and reduce emotional reactivity. Dan Harris, coanchor of ABC's Nightline, suffered a live panic attack linked to past drug use, which motivated him to discover meditation and mindfulness strategies that improved his mood by 10 percent.

Meditation physically changes the brain over time, altering brain waves and thickening regions associated with learning, memory, and emotion regulation. Wim Hof, nicknamed the Iceman, holds over twenty world records for feats like enduring extreme cold and ice baths through meditation, proving the mind's influence over the physical body. Mindfulness develops an acute, non-judgmental awareness of the present moment to help eliminate multitasking and automatic zoning out.

They Don't Feel the World Owes Them Anything

Believing that one deserves special treatment due to background, status, or unique hardships prevents personal accountability and hard work. Factors like overindulgent parenting, excessive self-esteem building, and social media fuel inflated self-importance.

Lucas, an MBA graduate starting his first job, complained that his coworkers were stupid and demanded a promotion, creating an office conflict that led HR to recommend counseling.

Focusing entirely on personal desires breeds bitterness and victim mentalities. True fulfillment comes from giving back without expecting rewards, accepting that life is not inherently fair, and realizing that personal problems are shared by many. Sarah Robinson, diagnosed with a brain tumor at age twenty-four, spent her final months establishing Sarah's House, a hospitality house for cancer patients, raising nearly a million dollars through volunteer efforts before passing away at twenty-six.

True resilience relies on discipline and personal responsibility rather than using childhood adversity or systemic obstacles as an excuse for entitlement. Wilma Rudolph contracted polio at age four, wore leg braces and orthopedic shoes, but through physical therapy walked normally by age twelve and went on to become the first American woman to win three gold medals in a single Olympic Game in 1960.

They Don't Expect Immediate Results

We live in a fast-paced, on-demand world of technology, microwave meals, and overnight success myths. This creates a cultural illusion that change happens instantly. However, expecting quick fixes leads to abandoning goals prematurely, taking dangerous shortcuts, or failing to prepare for long-term realities like retirement and personal development.

Twitter founder spent eight years creating mobile and social products before Twitter, and Amazon was not profitable for the first seven years.

Progress is rarely a straight line, and things often have to get worse before they get better. Parents in a parenting group tried ignoring attention-seeking tantrums. Their children briefly screamed louder, causing parents to mistakenly think ignoring did not work.

The ability to delay gratification and resist short-term temptation is instrumental to achieving long-term success and good health. James Dyson spent five years building over five thousand prototypes and fourteen years total before his bagless vacuum became a success in Britain.

Conclusion

Building true mental strength requires eliminating the self-destructive habits, negative thoughts, and emotional pitfalls that hold you back.

Mental strength is not about acting tough or suppressing your emotions. It is about developing the habits of thought, behavior, and emotion that allow you to reach your full potential despite inevitable challenges. The thirteen habits work together as an interconnected system. When you stop giving away your power and feeling sorry for yourself, you free up the energy needed to embrace change and focus on what you can actually control. You build resilience against setbacks and learn from your mistakes rather than repeating them.

To maintain this progress and continue growing, apply these practical rules to your daily life:

1. Monitor your thoughts continuously to catch negative patterns, self-doubt, and cognitive distortions before they dictate your actions.
2. Evaluate your emotional responses honestly to ensure your feelings are driving productive decisions rather than impulsive reactions.
3. Observe your behaviors daily to confirm your choices align with your core values and long-term goals instead of offering temporary comfort.
4. Practice patience with yourself as you eliminate bad habits and establish new patterns of mental resilience.
