There’s something nobody told us in school that would have changed everything.
Your brain can change. Your thoughts are not facts. And the story you’ve been telling yourself about who you are — the one that feels so solid, so true, so you — is not as fixed as it feels.
This is neuroplasticity. And understanding it, really understanding it, might be one of the most liberating things you ever do.
The iceberg you’re living inside
Freud’s iceberg analogy has stayed around for over a century for good reason — it’s still one of the most useful pictures we have of the mind.
The tip of the iceberg is everything you’re consciously aware of. Your thoughts right now. Your intentions. The version of yourself you’d describe if someone asked.
Just below the surface sits everything that could rise into consciousness at any moment — half-remembered feelings, old patterns that flicker up when you’re stressed or triggered.
And then there’s everything beneath that. Vast, largely invisible, and quietly running the show. Your unconscious mind contains everything you’ve ever experienced. Every book, every film, every overheard conversation. Every news story that made your stomach drop. Every time someone told you that you were too much, not enough, stupid, difficult, or unlovable. Every message you absorbed before you were old enough to question it.
Here’s the critical part: if, in the moment you received that message, you didn’t fully reject it — if some part of you let it in, even slightly — it didn’t just pass through. It sank. It settled. And over time, unexamined and unchallenged, it formed a belief.
And beliefs don’t stay quietly in the background. They shape how you see yourself, how you interpret what happens to you, what you think you deserve, and what you think is possible. All without you realising it’s happening.
So whose voice is that, exactly?
When you catch yourself thinking I always mess things up, or people will leave eventually, or I have to keep achieving or I’ll be found out, that voice feels like you. It feels like the truth.
But so much of the time, it isn’t. It’s an old message, absorbed young, never properly questioned, now masquerading as fact.
The good news, and this is where neuroplasticity comes in, is that it doesn’t have to stay that way.
Your brain is not set in stone
For a long time, we believed the brain was largely fixed after childhood. We now know that’s wrong. The brain retains the ability to form new neural pathways throughout our entire lives. New thoughts, practised consistently, literally reshape the brain over time.
This doesn’t mean you can simply decide to think differently and watch everything transform overnight. It’s not that simple, and anyone who tells you it is isn’t being straight with you. The unconscious beliefs that drive our behaviour weren’t formed in a day, and they won’t shift in one either.
But they can shift. That’s the point.
The train station, not the train
One of the most unhelpful things we were told about meditation was to clear your mind of thoughts. Think of nothing. Just let go.
If you’ve ever tried that — especially if your mind runs fast, if you have ADHD, if you’re someone who thinks in seventeen directions at once — you’ll know how well that goes. You try to think of nothing, and your brain treats it as a personal challenge.
Here’s a more useful image. Imagine your mind is a busy train station. Every train that pulls in represents a thought. Most of the time, we’re on the train, swept into the past or hurtling toward the future, thoughts spiralling, growing, pulling us further from the present moment.
What we’re actually trying to do — what meditation, therapy, and self-awareness practice all point toward — is to get to the platform. To become the observer. To watch the trains come and go without climbing aboard every single one.
That’s it. That’s the shift. Not silencing the thoughts. Watching them without being controlled by them.
Where to start
The most powerful first step isn’t positive thinking. It’s noticing.
When something difficult happens, especially something that triggers a strong reaction, pause and get curious. What just went through your mind? What did you immediately tell yourself about yourself? Was it kind? Was it fair? And crucially: is it actually true?
Is there real evidence for what you’re saying to yourself, or is it an old belief — something someone once said, something you decided about yourself in a painful moment — that you’ve been carrying ever since without ever stopping to question it?
Because if it isn’t true, you don’t have to keep believing it.
You are not your thoughts. You are the one who can observe them, question them, and, with time, support, and practice — change them.
That is not a small thing. That is everything.
If this has resonated and you’d like to understand your own patterns more deeply and actually start shifting them, I’d love to hear from you. Working together, we can begin to untangle what’s been running in the background and build something that genuinely serves you. Get in touch here.
