Summary
What separates those who believe they can from those who always second-guess themselves? It’s not talent—it’s self-belief, and it’s trainable.
In this third and final part of The Science of Success Series, Cody McBroom dives deep into the neuroscience of self-belief—revealing how your brain rewires based on action, feedback, and mindset.
Drawing from cutting-edge research in neuroscience and psychology, you’ll learn:
📌How self-affirmation rewires reward pathways and strengthens your ability to follow through
📌 Why positive feedback changes your brain’s circuitry and boosts self-efficacy
📌 The difference between high vs. low belief brain strategies—and how belief leads to smarter, more efficient performance
📌 Why self-belief is context-specific, but transferable through the right structure
📌 What successful people do daily to build and reinforce unshakable self-confidence
You’ll walk away with science-backed strategies to:
📌Reflect on your values to build neural trust in yourself
📌 Use feedback loops to reprogram self-doubt
📌 Transfer mastery from one domain (fitness, business, relationships) into others
📌 Practice pre-challenge self-affirmation to prime your mindset for high-stakes situations
If you’re ready to stop letting doubt dictate your potential and start training your brain for real confidence, this episode is your roadmap.

I'm going to show you exactly what is going on in your brain as you |

| 0:26.5 | develop more self-belief in your life today, and a literal checklist action plan that you can |

| 2:01.6 | self-belief. That's the main thing we want to know about, right? And that's what we're going to |
