What If You’re Not Broken — Just Miswired?
Most people think they’re stuck because they lack motivation. But Dr. Swart says:
“Your brain doesn’t care what you want. It only cares what’s familiar.”
Which means:
•
You might say you want success, but your brain sees struggle as safer•
You crave love, but chase the same emotionally unavailable types•
You have big goals, but sabotage them as soon as progress startsGood news? Brain wiring can change.
Brain wiring can change. The 4-Step Method That Rewires Your Reality
Dr. Swart’s method is science-based, but simple enough to start today:
1. Know What You Really Want
Use her 3-layer filter:
•
Head: What logically makes sense•
Heart: What emotionally excites you•
Gut: What feels physically energizingWhen all 3 say YES → that’s your real goal.
2. Mental Rehearsal
Your brain can’t tell the difference between real and vividly imagined.
•
Visualize it
•
Feel it in your body
•
Rehearse it like it's already happening
“If you can feel it, you can form it.”
3. Affirmations That Work
Say what your brain can believe:
•
Not: "I’m a millionaire"•
Try: "I’m learning to build wealth"It creates momentum without resistance.
4. Repetition + Routine
Neural rewiring = daily effort.
Try:
•
Journaling•
Gratitude each morning•
Intentional inputs (podcasts, affirmations, imagery)“You don’t manifest what you want. You manifest what you believe.”
The Hidden Villain: Stress
Here’s what most people never realize:
•
Stress is contagious — other people’s energy alters your biology•
Stress leaks through your skin — yes, people can sense it•
Stress stores as belly fat — chronic cortisol redirects fat to your midsectionAnd worst of all?
•
It shuts down creativity, intuition, and higher decision-makingBefore you transform your life, you need to calm your nervous system.
Tools:

Vision Boards Aren’t Woo-Woo (If You Use Them Right)
Tara explains: vision boards train your RAS (Reticular Activating System)
Your RAS filters 11 million+ bits of info per second. A vision board:•
Tells it what to pay attention to
•
Keeps your goals emotionally alive
•
Nudges you toward aligned action
BUT it only works if you:
it only works if you:•
Look at it daily
•
Feel something when you do
•
Use it as a signal, not a decoration
