2.1 📖 Mini-story recap

Ever wondered why happiness doesn’t last? Why a promotion, a new phone, or even a slice of cake only brings fleeting joy? According to Habits of a Happy Brain, it’s not because you’re ungrateful or mentally weak—it’s because your brain is running a 200-million-year-old survival program.

Loretta Breuning unpacks how our four “happy chemicals”—dopamine, serotonin, oxytocin, and endorphin—were designed not to keep us blissful, but to push us toward behaviors that kept our ancestors alive. Each one has a specific job:

  • Dopamine motivates you to chase rewards.
  • Serotonin gives you pride and status.
  • Oxytocin builds trust and bonding.
  • Endorphin masks pain and stress.

But here’s the kicker: those chemicals don’t last. Your brain gives you a short burst, then resets to “neutral,” always scanning for the next threat or opportunity. That’s why we end up chasing more—more food, approval, success, or likes—creating vicious emotional cycles.

The brilliance of this book is that it doesn’t just explain the science—it gives you a practical, doable roadmap. You’ll learn how to:

  • Recognize old, unhelpful habits that flood you with short-term pleasure but long-term stress.
  • Create new habits that feel awkward at first, but with 45 days of repetition, can rewire your brain to feel good for the right reasons.
  • Build daily “micro-habits” that activate happy chemicals using tools you already have—like posture, thoughts, gratitude, movement, and trust rituals.

This book isn’t about fixing your past or escaping negative emotions—it’s about harnessing your mammal brain and training it to release happiness in ways that truly support your well-being.

✅ What You’ll Take Away:

  • Your brain isn’t designed for happiness—it’s designed for survival.
  • You can train it to release happy chemicals in better, sustainable ways.
  • Happiness is a habit—not a miracle. And it takes just 45 days to build a new neural path.

If you’ve been stuck in the loop of instant gratification, self-sabotage, or emotional rollercoasters, this book will hand you the map—and the machete—to carve your way out.

Let me Explain it Chapter by Chapter for you


📘 Chapter 1 – Your Inner Mammal

📖 Mini-story recap

Imagine you’re a gazelle grazing peacefully when suddenly you hear a rustle in the grass. Instantly, your body reacts—not because you’re thinking logically—but because your mammalian brain is scanning for survival threats 24/7. Now, imagine you’re a modern human. You’re not running from lions, but your brain still lights up with panic when you’re late for a meeting or ignored at a party. Why? Because your brain is still wired like that gazelle’s. It’s always working to protect your genes, not just your feelings.

🧠 Key insight / mindset shift

Your brain is not built for constant happiness—it’s built for survival.
It rewards you with happy chemicals (dopamine, serotonin, oxytocin, endorphin) when it sees a survival advantage (food, status, trust, or relief from pain), and then quickly resets to neutral, preparing for the next threat or opportunity. That’s why our highs are short-lived and why we often fall into habits—good or bad—trying to recreate those chemical spikes.

✅ Exact instructions Loretta gives

  1. Understand the four happy chemicals and their roles:
    • Dopamine – Triggers joy when pursuing a goal or reward.
    • Endorphin – Masks pain, gives a momentary high.
    • Oxytocin – The bonding chemical, makes you feel safe with others.
    • Serotonin – The pride chemical, feels good when you’re respected.
  2. Accept your ups and downs as natural, not as emotional failure.
  3. Recognize that your emotional habits were wired in early childhood (before age 7).
  4. Know your brain builds ‘superhighways’ for repeated patterns—good or bad.

🔑 Pointers for action

  • 🧭 Stop blaming others (or yourself) for your moods—start understanding your brain’s wiring.
  • 🔄 Replace old emotional habits by consistently choosing new responses, even if they feel unnatural at first.
  • 🔍 Observe how your happy chemicals activate in your day-to-day life. What triggers them? What repeats?
  • 🧠 Remember: your brain loves repetition—it learns by doing, not by wishing.

💡 Closing Thought

You are not broken. You’re a well-built survival machine running ancient software. But now, you have the user manual. And you can choose to rewire it—with 45 days of focused practice, one new happy habit at a time.

📘 Chapter 2 – Meet Your Happy Chemicals

📖 Mini-story recap

Picture a hungry lioness pacing the savannah. She sees a gazelle, energy surges through her body—dopamine fires like a rocket. She pounces. That thrill? That’s not just instinct; it’s brain chemistry.
Now imagine yourself—checking your phone for likes, cracking a tough puzzle, or getting a promotion. That zing? Same chemicals. Different jungle.

🧠 Key insight / mindset shift

Your emotions are created by natural chemical surges, not random moods.
You don’t have to “feel happy” all the time. These surges evolved to motivate survival behaviors. They’re brief because their job is to nudge you toward action—not to keep you in bliss.

✅ Exact instructions Loretta gives

  1. Identify when each chemical activates in your life:
    • Dopamine: the joy of progress or a new opportunity.
    • Endorphin: numbs physical pain; released in intense exertion or laughter.
    • Oxytocin: trust and bonding; triggered by safe social contact.
    • Serotonin: pride and status; triggered by feeling respected or admired.
  2. Recognize that each chemical evolved for a specific purpose.
  3. Don’t expect constant highs—it’s not biologically possible.

🔑 Pointers for action

  • đŸ§Ș Track your happy chemical moments. Ask: What sparked that zing? What kind of reward was my brain detecting?
  • 🧠 Speak your brain’s language. Instead of wondering “Why am I not happy?” ask “What kind of reward am I unconsciously chasing?”
  • 🎯 Realize that you built your circuits. Your childhood rewards created your dopamine blueprint.
  • 🔄 Use awareness to replace the reward triggers that no longer serve you.

📘 Chapter 3 – Why Your Brain Creates Unhappiness

📖 Mini-story recap

A gazelle is munching grass peacefully until it smells a lion. Boom—cortisol floods its system. It runs for life.
Now imagine you’re sitting in your office and feel a wave of dread—your boss gives you a look. Your body tightens. Why? Cortisol doesn’t care whether it’s a lion or a passive-aggressive email—it reacts the same way.

🧠 Key insight / mindset shift

Unhappy chemicals serve a survival function—don’t demonize them.
Cortisol evolved to alert you to threats. The problem? In modern life, we confuse discomfort (awkward moments, judgment, traffic) with survival threats.

✅ Exact instructions Loretta gives

  1. Understand cortisol as an alarm system—not an enemy.
  2. Recognize vicious cycles:
    • Bad feelings spark habits like snacking, scrolling, arguing.
    • These trigger a quick happy surge.
    • Then you crash—and repeat.
  3. Interrupt the cycle by resisting the “do something” urge.

🔑 Pointers for action

  • ⚠ Notice your triggers. What sparks your discomfort? That’s your “lion.”
  • ⏞ Pause instead of reacting. Let the cortisol spike pass—don’t rush to numb it.
  • 💡 Design alternate responses. Choose small, healthy actions instead of automatic habits (e.g., go for a walk instead of eating a donut).
  • 📆 Commit to repeating that better action for 45 days. That’s how you rewire.

đŸ§© Final thought for this batch

Your brain is not designed to make you feel good all the time. It’s designed to motivate you to act. Understand the chemical whispers, and you’ll stop being ruled by them.

📘 Chapter 4 – The Vicious Cycle of Happiness

📖 Mini-story recap

Imagine you’re a student. Every time exam stress hits, you instinctively reach for a chocolate bar. You feel good instantly. That’s your brain firing dopamine to numb the cortisol storm. But soon, guilt creeps in. You’ve just entered a vicious cycle—a chase for happiness that ends in more distress.
And your brain? It just paved a stronger neural highway: “Exam stress = chocolate = relief.”

🧠 Key insight / mindset shift

What feels like “doing something” to feel better might actually be reinforcing unhappiness.
Every time you soothe discomfort with a quick-fix habit (snacking, scrolling, overworking), your brain gets trained: “This solves my problem.” But that solution fades fast—and leaves you worse off.

✅ Exact instructions Loretta gives

  1. Understand how your brain links relief with habit.
  2. Track what you do to escape a bad feeling—and how long that relief lasts.
  3. Recognize how these patterns build neural “superhighways.”

🔑 Pointers for action

  • 🧠 Watch your brain’s shortcut cravings. “Just one treat
” is a chemical survival script.
  • đŸ§± Build new neural roads: Choose an action that’s actually helpful, and do it daily for 45 days.
  • đŸš« Resist the urge to numb discomfort instantly. Cortisol fades—even if you do nothing.
  • 🔄 Interrupt the cycle with awareness: “I’m not broken. I’m wired to chase relief—but I can rewire.”

📘 Chapter 5 – How Your Brain Wires Itself

📖 Mini-story recap

A child gets applause every time she dances. Her brain floods with serotonin. Over time, she builds a neural trail: “Dancing = feeling valued.” Fast forward: as an adult, she feels invisible in meetings and doesn’t know why she craves attention.
That’s not ego—it’s wiring from early emotional circuits, laid down long before logic stepped in.

🧠 Key insight / mindset shift

Your core emotional habits were built in your early years—by repetition, not reason.
Neural trails form through repeated emotional experiences. Some lead to happiness. Others become potholes of pain. But here’s the good news: neural wiring can change.

✅ Exact instructions Loretta gives

  1. Recognize that your brain follows the path of least resistance.
  2. Understand that old habits feel “true” only because they’re familiar.
  3. Know that new trails require effort, repetition, and discomfort.

🔑 Pointers for action

  • 🌿 See your old patterns for what they are: practiced reactions. Not truths.
  • 🔄 Choose one new response—a thought, habit, or emotion—and rehearse it daily.
  • đŸš¶â€â™€ïž Repetition = paving new neural roads. Do it even if it feels weird or wrong.
  • 🧭 Act based on the future you want—not the past that wired you.

🧠 Final shift for this batch

You’re not your thoughts—you’re your wiring. But that wiring is changeable. 45 days of a new habit is like cutting a fresh trail through the jungle of your brain. Keep walking it, and it becomes a road.

📘 Chapter 6 – New Habits for Each Happy Chemical

📖 Mini-story recap

Think of Maya, who used to snack every time she felt stressed. Now, instead of reaching for chips, she opens her “happy habit journal” and does 5 jumping jacks or sends a kind message to a friend. At first, it felt awkward and pointless. But day by day, it grew easier. On day 46, it felt natural—and even better, it triggered the same happy chemicals.
What changed? Her brain had a new reward circuit.

🧠 Key insight / mindset shift

You can reprogram your happy chemicals by building new habits—on purpose.
You can’t expect new habits to feel instantly good. But if you persist for 45 days, your brain starts associating them with dopamine, serotonin, oxytocin, or endorphin.

✅ Exact instructions Loretta gives

  1. Choose ONE happy chemical to work on at a time.
  2. Select a behavior that naturally stimulates it (see list below).
  3. Repeat that behavior once per day for 45 days.
  4. Don’t skip a day—if you do, start over from day 1.
  5. Track it visually—create a “happy habit calendar” to reinforce progress.

🔑 Happy Habit Examples

For Dopamine (reward-seeking):

  • Break big goals into tiny steps, and celebrate each.
  • Track small wins (checklists, streaks, milestones).

For Endorphin (pain-masking):

  • Laugh daily (watch comedy, tell jokes).
  • Stretch or exercise (to reasonable discomfort).

For Oxytocin (bonding):

  • Hug someone you trust.
  • Make time for shared activities or eye contact.

For Serotonin (status/pride):

  • Acknowledge your wins.
  • Stand tall, speak with confidence, practice gratitude for your strengths.

🔑 Pointers for action

  • 🔄 Build a mini-ritual: e.g., “At 9 AM, I write 3 proud moments.”
  • 🧠 Remember: old habits feel good because they’re practiced—not because they’re “right.”
  • ⏳ Be patient. Rewiring the jungle of neurons takes time.

📘 Chapter 7 – Your Action Plan

📖 Mini-story recap

Meet Raj. He was hooked on chasing approval—his brain’s serotonin fix. After learning about happy chemicals, he created a 45-day plan: every day, he stood tall, recalled one personal win, and wrote it down. It felt silly at first, but by week 3, he noticed confidence creeping in—and old triggers losing their grip.
He didn’t “get better.” He got rewired.

🧠 Key insight / mindset shift

Consistency rewires your brain—not willpower or motivation.
If you rely on “feeling like it,” you’ll fail. But if you follow a simple plan daily, your brain learns to associate that behavior with reward. That’s how new habits become natural.

✅ Exact instructions Loretta gives

  1. Pick one happy chemical.
  2. Choose a small daily action to stimulate it.
  3. Set a time and place to do it.
  4. Track your behavior for 45 consecutive days.
  5. Ignore whether it “feels good” at first—keep going.
  6. Repeat with a new habit after day 46.

🔑 Pointers for action

  • 📆 Use a visual tracker (calendar, journal, app).
  • 📍 Anchor your habit to something stable (after brushing teeth, before lunch, etc.).
  • ⛔ Avoid switching midstream. Stay with one habit until it’s ingrained.
  • 🧭 Celebrate your process—not perfection.

💡 Final thought for this batch

You don’t need to fight your brain—you just need to train it. Your chemistry isn’t broken. It’s just running old scripts. And now, you have the power to write new ones—one small, repeated action at a time.

📘 Chapter 8 – Overcoming Obstacles to Happiness

📖 Mini-story recap

Leena wanted to build a gratitude habit for serotonin. But every time she tried, her mind shouted back, “You’re not doing enough!” or “This is silly!”
She almost gave up—until she realized: these were just old neural highways, carved by years of critical thinking. She didn’t need to argue with them—just build new ones.

🧠 Key insight / mindset shift

Old habits will fight back—but that’s proof your brain is working.
Your brain prefers what’s familiar, even if it makes you unhappy. It believes old neural circuits are safer because they’ve been “tried and tested.”

✅ Exact instructions Loretta gives

  1. Expect discomfort when building a new habit—it’s normal.
  2. Treat old habits like overused highways and new ones like trails needing clearing.
  3. When you miss a day or fall off, don’t panic. Restart at Day 1.
  4. Do not try to suppress old thoughts—instead, gently redirect.

🔑 Pointers for action

  • 🚧 Plan for resistance: Know it will come and doesn’t mean failure.
  • 🧠 Talk to your brain like it’s a child: “Yes, I know you’re scared, but we’re trying something new now.”
  • ⏳ Repetition beats motivation. Don’t wait to feel good—train to act regardless.
  • 📖 Review your “why” often. Why are you building this habit? Let that anchor you.

📘 Chapter 9 – Rely on Tools That Are Always with You

📖 Mini-story recap

Sam wanted peace but kept reaching for social media whenever he felt low. Then he realized—he had better tools right inside his brain.
He began choosing 3-second rituals like stretching, deep breathing, or mentally reliving a win. Slowly, his brain started associating these tools with reward. And that changed everything.

🧠 Key insight / mindset shift

The best happiness tools are built-in—and free.
You don’t need exotic retreats or a perfect childhood to feel good. You just need to activate your own neurochemicals with small, daily inner habits.

✅ Exact instructions Loretta gives

  1. Create short, portable rituals (e.g., smile at yourself, recall a moment of pride, tighten & release a muscle).
  2. Use sensory anchors (music, smells, touch) that reliably spark happy chemicals.
  3. Design “emergency rituals” for when cortisol strikes (e.g., repeat an empowering word, do 10-second breathing).
  4. Use visualization: mentally relive a past success or safe bonding moment.

🔑 Pointers for action

  • 🧰 Create a toolkit of 3-second habits. These micro-moves build neural safety nets.
  • đŸŒ± Train your brain to see safety, not threats. That reduces cortisol.
  • 🔄 Replace scrolls & snacks with something inner and intentional.
  • đŸ§˜â€â™€ïž Remember: calm is a skill—not a gift. You grow it.

🧠 Final thought for this batch

The world may stay chaotic, but your inner world can become your sanctuary. You now hold the tools to retrain your brain—to build happiness circuits that don’t depend on anyone else.

✅ What to Do Now:

You’ve completed the book. To integrate it:

  • Choose 1 happy chemical to focus on this week.
  • Pick 1 micro-habit from that chemical’s list.
  • Practice it daily for 45 days, tracking your progress.
  • Then move to the next. And the next.
    That’s how you build a truly happy brain—for life.
