Empowerment Coach and founder of Own Your Life, Julie Vander Meulen pioneers in researching and applying personal development strategies to help ambitious women overcome the good girl syndrome and become the powerful individuals they were always meant to be.
In a world where achievement often feels like the key to overcoming self-doubt, Julie Vander Meulen explores the deeper roots of self-questioning in her article, From Self-Doubt to Self-Trust: Rewiring the Good Girl Brain. This piece delves into how the patterns of people-pleasing and perfectionism, ingrained from a young age, can rewire the brain, making self-doubt a default response. Julie offers practical steps to repattern these instincts and build self-trust, empowering women to lead from within.
When confidence feels like a costume
I used to think self-doubt was something I could out-achieve.
If I just collected enough gold stars, enough praise, degrees, promotions, or compliments, maybe the voice in my head would finally quiet down.
But it didn’t. Because here’s the truth: Good Girl Syndrome doesn’t just shape your behavior; it rewires your brain.
It teaches you to second-guess your instincts, outsource your self-worth, and look for safety in other people’s approval instead of your own knowing.
So, even when you seem confident, there’s often a quiet loop running underneath:
“What if I’m wrong?”
“What if I fail?”
“What if they find out I have no idea what I’m doing?”
And that loop? It’s not a personality flaw. It’s a survival pattern.
Why the good girl brain can’t just “think positive”
If you grew up being praised for being “good,” your brain learned early on that approval equals love, and disapproval equals danger.
So, it makes sense that you’re hyper-attuned to other people’s opinions. That your first instinct is to seek reassurance, not self-validation.
This is why mindset work alone isn’t enough. You can’t just throw affirmations at a nervous system that’s still wired for perfectionism, people-pleasing, and performance-based love.
You have to repattern your relationship with your own inner authority
.You have to rebuild trust from the inside out.
What self-trust really looks like
Self-trust doesn’t mean you never feel doubt.
It means you don’t obey it.
It means you know how to pause before you panic.
How to hear your fear without handing it the steering wheel.
How to source your decisions from alignment, not anxiety.
Self-trust means:
You can hear your own voice in the noise.
You can disappoint someone else without betraying yourself.
You know how to repair your own safety when your brain starts spinning.
It is not built through perfection; it is built through repetition.
Through taking tiny, brave steps again and again until your nervous system learns a new truth:
I can trust myself and still be safe.
How to rewire your brain for self-trust
Here’s where I suggest starting:
First, catch the doubt early. Notice when your brain slips into self-questioning spirals. Get curious: Is this my truth, or is this a Good Girl reflex?
Second, pause before seeking reassurance. Just for 5 minutes. Give yourself a moment to ask: “What do I think? What feels true for me right now?”
Third, anchor safety into your body. Self-trust isn’t just a thought; it’s a felt experience. Place your hand on your heart. Ground your feet. Speak out loud:
“I can trust myself, even here.”
“I don’t need to be perfect to be wise.”
“I’ve got me.”
You’re not trying to erase doubt. You’re trying to outgrow the part of you that only felt loved when she was agreeable, quiet, or “good.”
Becoming the woman who leads herself
Every time you choose your voice over your fear, your clarity over your conditioning, you’re creating a new identity, one rooted not in compliance, but in sovereignty.
Because here’s the most powerful truth: You were never meant to fit in.
You were meant to lead your life, your work, your world.
And leadership starts with self-trust.
