Psychotherapist Amy Morin wrote the viral article that became this book after experiencing devastating personal losses in quick succession. Her observations about mental strength revealed something unexpected: strong people aren't defined by what they do — they're defined by what they refuse to do.
In 2026, as economic uncertainty reshapes careers and AI forces constant adaptation, mental resilience has become the differentiator between those who thrive and those who burn out. You're facing more change in a single year than previous generations faced in a decade. The professionals who stay steady aren't superhuman — they've simply stopped engaging in the 13 self-destructive habits that drain everyone else's mental energy.
Headway, a daily growth app trusted by 55 million users worldwide, breaks down Amy Morin's '13 Things Mentally Strong People Don't Do' into quick insights you can apply immediately. Whether you're commuting, waiting in line, or brushing your teeth, you can start eliminating the habits that are sabotaging your mental strength.
➡️ What is Headway and how does it work?
They don't waste time feeling sorry for themselves
Morin identifies self-pity as the first mental strength killer. It's not about denying that bad things happen — they do, and often unfairly. It's about refusing to get stuck in a cycle of victimhood. Self-pity feels temporarily comforting, like emotional quicksand that's easy to sink into but impossible to build on.
The trap works like this: when you focus on how unfair your situation is, you surrender your power to change it. Your attention shifts from "What can I do?" to "Why is this happening to me?" That subtle shift transforms you from an agent who acts into a victim who reacts. Mentally strong people acknowledge their difficulties, then immediately ask what's within their control.
The insight that changes everything: You can either have self-pity or progress, but you can't have both. Every minute spent dwelling on how things should be different is a minute not spent making them different.

They don't give away their power
Giving away your power means letting other people control how you feel, what you think, or what you're capable of achieving. It shows up when you say things like "My boss makes me so angry" or "My family won't let me pursue my goals." These statements frame you as powerless, even when you're not.
The reality: no one can make you feel anything without your permission. Someone can do something hurtful, but you choose your response. Your coworker can criticize your work, but you decide whether that criticism defines you or informs you. This isn't about toxic positivity — it's about recognizing where your actual control begins and ends. You can't control what people say about you. You can control whether you give those words authority over your self-worth.
The practical shift: When you catch yourself saying someone "made" you feel something, rephrase it. "I feel angry about what my boss said" puts you back in the driver's seat. "She makes me furious" hands her the steering wheel. That linguistic change reflects where your power actually lives — in your response, not in their action.
With over 2,500 concise book summaries, Headway helps you examine mental resilience from a wide range of perspectives — from ancient Stoicism to contemporary psychology. As you explore powerful ideas in focused 3–20 minute sessions, you start recognizing patterns in your own thinking more clearly.
📘 See the difference for yourself. Many users say that encountering their limiting behaviors, as described across multiple books, gave them the clarity they needed to finally change habits that had held them back for years.
They don't avoid change
Most people claim they hate change when they actually fear loss. Every change involves losing something — familiarity, comfort, certainty about what comes next. Mentally weak responses try to prevent all change, preserving the status quo at any cost. Mentally strong people accept that change is inevitable and focus their energy on adapting effectively.
The mistake people make is treating change as an emergency. When your company restructures, your relationship evolves, or your industry shifts, the instinct is panic. Mentally strong people treat change as information. What does this tell me about what's needed now? What skills do I need to develop? What old approaches should I discard? They're not fearless — they just refuse to let fear drive decisions.
What this means for you: The goal isn't embracing every change enthusiastically. It's accepting that resisting inevitable change burns more energy than adapting to it. When AI reshapes your role, you can spend six months insisting your old methods were better, or you can spend those six months learning the new system. Either way, the change is happening. Only one response leaves you employable.
📘 Start your mental strength practice with Headway's bite-sized wisdom delivered every morning that you can practice throughout your day. Users consistently report that small daily doses of mental resilience concepts compound into major behavioral shifts over months.
Build your mental strength by subtracting, not adding
Morin's book proves that mental strength isn't about doing more — it's about doing less of what weakens you. In 2026's overwhelming world, the ability to identify and eliminate self-destructive patterns matters more than adding another productivity hack.
Headway makes building this awareness simple and fun. Beyond '13 Things Mentally Strong People Don't Do,' you'll find 2,500+ book summaries in text and audio covering psychology, resilience, emotional intelligence, and personal development. The app's gamified challenges turn abstract concepts into daily practices — whether you're standing in line, floating in a pool, or commuting to work.

Frequently asked questions about building mental strength and Amy Morin's book
What exactly is mental strength, and how is it different from being tough?
Mental strength is the ability to regulate emotions, manage thoughts, and take productive action despite difficult circumstances. Being "tough" often means suppressing emotions or powering through problems without processing them. Mental strength involves acknowledging emotions without being controlled by them, learning from failure instead of denying it, and setting boundaries rather than simply enduring everything. Mentally strong people feel their feelings fully — they just don't let those feelings make their decisions.
Can you really build mental strength, or is it something you're born with?
Mental strength is absolutely trainable, just like physical strength. You're not born with fixed levels of resilience. Morin's framework focuses on eliminating destructive habits, which creates space for strength-building habits to develop naturally. Every time you catch yourself feeling sorry for yourself and redirect that energy toward action, you're strengthening neural pathways. Over time, the productive response becomes more automatic. Genetics might influence your starting point, but consistent practice determines where you end up.
Which of the 13 things should I focus on eliminating first?
Start with whichever habit you recognize most clearly in yourself. Self-awareness is more important than sequence. If you constantly give away your power by blaming circumstances for your emotions, start there. If you dwell on the past and let old resentments drain your energy, tackle that first. Trying to eliminate all 13 simultaneously overwhelms your capacity for change. Pick one, practice alternatives for two to three weeks until new patterns feel automatic, then add another.
How do I stop these behaviors without being too hard on myself?
Mental strength includes self-compassion, not self-criticism. When you notice yourself engaging in a destructive habit, the response isn't "I'm weak, and I'm failing." It's "I'm human, and I'm learning." Mentally strong people acknowledge setbacks without catastrophizing them. You broke your streak of not feeling sorry for yourself? That's information about your triggers, not proof you're incapable of change. The goal is progress, not perfection. Self-punishment is itself a form of mental weakness.
What if my environment makes mental strength impossible?
Your environment affects the difficulty level but doesn't determine impossibility. If you're in a genuinely unsafe or abusive situation, prioritizing physical safety comes first — that's mental strength in action, not weakness. But most environments aren't impossibly hostile, just challenging. You can't control whether your workplace is toxic, but you control whether you internalize that toxicity. You can't control your family's dysfunction, but you control whether you adopt their patterns. Mental strength often means recognizing which battles to fight and which environments to leave.
How long does it take to see real changes from practicing mental strength?
Small shifts appear within days — you'll notice yourself catching destructive thoughts earlier. Meaningful behavioral changes typically emerge after three to six weeks of consistent practice. A life-altering transformation usually takes three to six months of deliberately redirecting old patterns. This isn't linear progress. You'll have weeks where you backslide, especially under stress. The key is whether you're slowly trending toward strength over months, not whether every day is perfect. Mental strength is a direction, not a destination.
Can you be too mentally strong? Is there a downside?
Genuine mental strength includes flexibility, empathy, and self-awareness, so by definition, you can't have "too much." What people sometimes call being "too mentally strong" is actually rigidity or emotional suppression — both signs of weakness disguised as strength. Mentally strong people cry when they're sad, admit when they're wrong, ask for help when they need it, and change their minds when new information emerges. If your version of mental strength makes you inflexible, judgmental, or disconnected from emotions, you've misunderstood the concept.
