The Motivation Loop: How Your Brain Decides What’s Worth Doing
Season 15, Episode 392 introduces phase two of the roadmap: neurochemistry and motivation. Andrea Samadi breaks down the motivation loop—expectation, thought patterns, attention and action, feedback, and repetition—and explains how belief and dopamine drive what we start, persist with, or stop.
The episode highlights earned vs. borrowed dopamine, the role of the anterior mid-cingulate cortex in willpower, and offers practical steps to build sustainable motivation through small wins, effort-first rewards, and consistent practice.
✅ What You’ll Learn in This Episode✔️ How the Motivation Loop works—and why your brain is always running it
✔️ Why dopamine is about anticipation, not just pleasure
✔️ The difference between borrowed vs earned dopamine—and how it impacts your drive
✔️ How your beliefs and thought patterns shape your brain chemistry
✔️ Why doing hard things strengthens willpower (aMCC) and builds resilience
✔️ What causes motivation to increase… or break down
✔️ How your brain decides to repeat a behavior—or avoid it next time
✔️ Why effort first, reward after is the key to building lasting motivation
✔️ Simple ways to train your brain to stay motivated
✔️ How to align your brain for sustained performance and results
Welcome back to Season 15 of the Neuroscience Meets Social and Emotional Learning Podcast. I’m Andrea Samadi, and it’s here that we bridge the science behind social and emotional learning, emotional intelligence, and practical neuroscience—so we can create measurable improvements in well-being, achievement, productivity, and results.
If you’re new here, welcome.
We are currently reviewing past episodes as part of Season 15—organized as a roadmap of the brain’s foundational systems. Instead of treating neuroscience, health, mindset, and performance as separate topics—like we’ve done in the past 14 seasons—we’re now exploring how these systems come online in sequence.
We started Phase 1, Regulation and Safety, with EP 384[i], with Dr. Baland Jalal, who taught us how learning begins (with curiosity, sleep, imagination and creativity), and reviewed anchor episodes with Dr. Bruce Perry[ii], looking into trauma, rhythm, and relational safety, Dr. Sui Wong[iii] on autonomic balance, and Rohan Dixit[iv], on HRV, real-time self-regulation and nervous system literacy.
Now, we are moving to Phase 2, diving deeper into neurochemistry and motivation…then we’ll cover movement, learning, and cognition… Then perception, emotion, social intelligence… and finally integration, insight, and meaning as we put all of the phases together.
Season 15 Roadmap:
-
Phase 1 — Regulation & Safety
Phase 2 — Neurochemistry & Motivation
Phase 3 — Movement, Learning & Cognition
Phase 4 — Perception, Emotion & Social Intelligence
Phase 5 — Integration, Insight & Meaning
Because peak performance isn’t built by doing more— it’s built by aligning the systems underneath.
And the truth is, most of us were never taught how these systems drive our behavior and results in the first place.
So as I continue to explore and better understand these systems myself, I want to thank you for joining me on this journey… So that together, we learn how to align our brains— and use this understanding to unlock what’s truly possible for us to achieve.
Because I do believe that we’re capable of achieving far more than we think is possible—with this understanding.
PHASE 2
Today, we move into Phase 2 of our roadmap— Neurochemistry and Motivation.
In Phase 1, we asked a foundational question: 👉 Is the nervous system safe enough to learn?
Because without safety, nothing else in the brain fully activates.
But once the brain is regulated… a new question begins to emerge:
👉 What actually drives us forward?
What determines whether we start something… stay with it… or stop it altogether?
We will cover 6 PARTS in this episode, where we will answer this question, give some real world examples, and come up with some action steps to help us to build motivation the right way, where it’s sustainable in our day to day life.
🧠 PART 1 — THE MOTIVATION LOOP
At the center of Phase 2 is a system that is always running in the brain:
👉 The Motivation Loop
This is the system where belief, thought patterns, neurochemistry, action, and feedback all come together to shape our behavior and results.
Because learning isn’t just about understanding what to do—
👉 it’s about having the drive to actually do it.
Because motivation isn’t random. It’s built.
👉 This loop determines:
-
What you start
What you stick with
And what you avoid
“My hope is that by the end of this episode, we can recognize our own motivation loop—and understand how our brain is guiding us to either push forward… or let go.”
🔁 Overview of The Loop:
✔Belief (Expectation) — “This matters” / “This is worth doing” ✔Neurochemistry (Dopamine) — rises before action ✔Action (Effort) — you begin ✔Feedback (Reward or Not) — brain evaluates outcome ✔Repeat or Avoid — behavior is reinforced… or not
WHAT STEPS DRIVE SUSTAINED EFFORT AND FORWARD MOVEMENT?
Step 1: Expectation through what you BELIEVE
This starts in the prefrontal cortex—the thinking brain.
👉 This is where we set a goal or form a belief:
-
“This matters”
“This will feel good”
“This is worth doing”
This step is critical because:
👉 The brain is predicting the future
If the brain expects something to matter— 👉 dopamine begins to rise before you even start
THINK AHEAD: 👉 What matters most to you right now?
👉 What do you expect to achieve?
Because what you expect…
👉 Is what your brain begins to move toward.
Step 2: Thought Patterns Your thoughts shape your brain chemistry.
-
Positive expectation → dopamine increases → effort rises
Negative thinking → dopamine drops → motivation decreases
👉 Your thoughts are not neutral.
They are chemical.
This is where things start to shift internally.
👉 Your thoughts don’t just stay in your mind—they directly influence your brain chemistry. We’ll dive deeper into this one area with Dr. Carolyn Leaf’s work.
THINK AHEAD: Are your thoughts helping you move forward… or holding you back?
Are you thinking: ✔“This matters. I can do this.” Or ❗ “This is too hard… I’m not sure I can.”
Because once you notice this…
👉 You know exactly where your work lies.
Step 3: Attention/Reward
Now the brain engages:
-
Motor + attention systems engage
Dopamine fuels drive
-
Movement = “turning on” the brain for motivation
We will learn more on this area (focus, engagement and memory formation) with John Medina, but until then
THINK AHEAD:
“What would it feel like to be fully engaged in this?” “What’s one small action I can take to get started?” “How will I feel once I’ve begun?”
Because this is the moment where:
The brain shifts from thinking… to doing.
Step 4: Feedback (Reward or Not)
-
Brain evaluates outcome
Dopamine either:
-
Spikes (better than expected)
Drops (worse than expected)
👉 Immediately ATTENTION/REWARD
The brain asks:
👉 “Was that worth it?”
You see an orange arrow that either goes forward in the LOOP, or backwards if there’s no reward.
Step 5: Learning & Repetition
-
Basal ganglia encode the behavior
Habit circuits strengthen (or weaken)
👉 Your brain is deciding:
👉 “Is this worth repeating?”
🎯 KEY INSIGHT
👉 The brain isn’t just tracking what you do… 👉 It’s learning what’s worth doing based on what you BELIEVE.
Do you see how this motivation loop works? This really is exciting to me, that we have a lot of control of what we want to achieve, based on how we think about it. We’ll go deeper into this next week with our anchor episode starting with Bob Proctor on belief, and then Dr. Carolyn Leaf on the power of our thoughts.
🧠 PART 2 — THERE’S A RULE ABOUT MOTIVATION
And this leads us to one of the most important rules in neuroscience:
👉 If dopamine comes too easily — effort stops feeling worth it. 👉 If dopamine is earned — effort becomes rewarding.
This isn’t just mindset.
It’s brain-based.
Dopamine = Anticipation, Not Just Pleasure
Most people think dopamine is the “feel-good” chemical.
It’s not.
👉 Dopamine is the “this is worth doing” signal
-
Released when you expect a reward (not just receive it)
Drives effort, focus, and persistence
“Dopamine doesn’t reward you after the fact — it pulls you forward before you begin.”
This was covered in our Think and Grow Rich[v] book series from 2022. It always amazes me when a book that was first published in 1937, connects to the success principles that we are learning today, almost 90 years later. Expectation and belief are integral components to Chapter 1, The Power of Thought.
🧠 PART 3 — BUILDING WILLPOWER (aMCC)
Thinking back to the motivation loop, I wondered, what is it that keeps me motivated on one thing, and dragging my feet with another. Understanding how the brain works has helped me to understand this question.
One of the most fascinating discoveries in neuroscience today comes from research on a part of the brain called the anterior mid cingulate cortex. (aMCC on our loop diagram). We covered this important discovery about the brain on EP 344[vi], The Neuroscience of Resilience: Building Stronger Minds and Teams.
On this episode, we covered some fascinating research from Stanford Professor Dr. Andrew Huberman with his guest David Goggins as they discussed “How to Build Will Power.” [vii]
What scientists are finding is that this area doesn’t grow when we do things that are easy — it grows when we do things we don’t want to do. When we push through resistance, when we finish the workout, when we say no to something tempting — this part of the brain actually strengthens.It’s now being linked not just to willpower, but to resilience, longevity, and even what some researchers are calling the ‘will to live.’So motivation isn’t about waiting to feel ready — it’s about doing hard things, especially when you don’t feel like it — because that’s what builds this system.”
REVIEW: There’s a key part of the brain:
👉 Anterior Mid-Cingulate Cortex (aMCC)
Responsible for: ✔Persistence ✔Willpower ✔Doing hard things
🎯 KEY INSIGHT
👉 This part of the brain grows when you do things you don’t feel like doing
👉 The moment you want to quit… is the moment your brain is changing
And here’s the key:
👉 It grows when you do things you don’t feel like doing… but do anyway.
You can see the aMCC part of the brain on the Motivation Loop Diagram right where the orange arrows either move us forward to movement, or backwards.
Understanding this part of the brain, helped me to understand why I want to quit sometimes when things are difficult, but the importance of pushing through, to build a stronger, more resilient brain.
🧠 PART 4 — BORROWED vs EARNED DOPAMINE
This one made me think, because I always hear people looking for a quick fix for motivation. My family members included as I have recently been asked the question “Hey Mom, can we buy these energy drinks to help me get motivated to go to the gym?” My answer was a solid “no” but I didn’t have the best explanation as to why I don’t think this is the best idea, until I wrote this episode.
Understanding the chemicals in our brain helps to explain this one and the fact that not all dopamine is equal.
🔴 BORROWED DOPAMINE
Fast. Easy. Immediate.
Examples: ✔ Scrolling before starting ✔ Sugar when stressed ✔ Energy drink before a workout
👉 Feels good BEFORE effort
❗ Result:
-
Weakens the loop
Lowers motivation over time
Creates dependency
🟢 EARNED DOPAMINE
Slower. Effort-based. Long-lasting.
Examples: ✔ Finishing a workout ✔ Writing when you don’t feel like it ✔ Completing something difficult when you feel tired (like going to the gym)
👉 Feels good AFTER effort
✔ Strengthens the loop ✔ Builds internal motivation ✔ Rewires the brain
🎯 KEY TAKEAWAY
👉 Borrowed dopamine feels good now… 👉 Earned dopamine builds your future.
🧠 PART 5 — REAL-LIFE APPLICATIONS
We all experience this:
✔Activities with meaning and progress → easier to start ✔Activities with delayed reward → harder to begin
THINK about what’s EASY for you to do, versus where it’s more difficult to begin. This is where the work begins, as the harder to begin activities will build a stronger, more resilient brain.
🔹 My Personal Example: Hiking Insight
At the end of a long hike I noticed something significant. Now I had hiked the same distance the day before, so I was tired, but I noticed that the last 30 minutes were really difficult for me to complete.
✔ Effort increased ✔ Reward dropped
👉 The loop broke 👉 Motivation dropped
At the end of the hike, I thought “I need a break from these long hikes!” It was a long, difficult walk to my car.
🎯 KEY INSIGHT
👉 When effort outweighs reward repeatedly… 👉 The brain lowers motivation to protect you
I could in REAL-TIME see my motivation loop breaking, and going backwards. If I didn’t think about the benefits of doing difficult things on my brain, I might have given myself a weekend off. But doing difficult things, builds the aMCC in our brain, and this AHA moment, has kept me pushing through challenge, with my brain in mind.
🧠 PART 6 — CONNECT BACK TO THE LOOP
Every action trains your brain:
✔ Easy reward first → weak loop ✔ Effort first → strong loop
🎯 LONG-TERM RESULT
👉 Effort stops feeling like resistance
👉 And starts feeling like progress if you can keep going.
This is what happens when you get in the groove, and keep going to the gym, or when I pushed through with my hikes, and made them non-negotiable weekend events, and also for me, why it’s easier to write these podcast episodes when I do them regularly, every weekend. Taking time off, weakens the loop, and makes it more difficult to get started again.
✅ TIPS TO PUT THESE IDEAS INTO ACTION
🎯 Build Motivation the Right Way:
✔ Start easier than you think → Create early wins
✔ Reward AFTER effort (not before) → Train the correct loop
✔ Stop before exhaustion → Protect your motivation system
✔ Repeat before increasing difficulty → Consistency builds the loop
🎯 SIMPLE RULE
👉 Effort → Reward → Repeat
🔚 REVIEW + CONCLUSION
To review and conclude EP 392, as we launch Phase 2 on Neurochemistry and Motivation, let’s bring this all together.
Motivation isn’t something you have…
👉 It’s something you build
Through a loop of: ✔ Belief ✔ Action ✔ Feedback ✔ Repetition
Through a loop:
-
What you believe
What you do
What you experience
And how your brain evaluates it.
✔ Borrowed dopamine → weakens motivation ✔ Earned dopamine → builds motivation
🔗 PHASE CONNECTION
✔ Phase 1 — Regulation & Safety 👉 We stabilized our energy system
✔ Phase 2 — Neurochemistry & Motivation 👉 Now we activate it
🎯 FINAL THOUGHT
Because peak performance isn’t built by doing more…
👉 It’s built by aligning how the brain actually works
I hope you can see now how to build a stronger more resilient brain, with this understanding of the motivation loop.
We’ll see you next week as we step into our anchor episodes—beginning with Bob Proctor, where we explore the role of belief in driving behavior, results and direction.
Phase 2 Anchor Episodes-
Belief (Bob Proctor) → It’s our belief that determines our direction
Thoughts (Dr. Carolyn Leaf) → Internal chemistry
Attention (John Medina) → Focus + encoding
Energy (Friederike Fabritius) → Sustainability
Movement (Dr. Hillman) → Activation
