The introvert OS nobody talks about


You don’t need fixing. You just need to understand your wiring.

Hey Reader,

In every job or contract role I've ever had, I've always dreaded team meetings.

By the time I’d pieced together what people were really saying, the conversation had already moved on.

If I stayed quiet, colleagues assumed I wasn’t engaged.

If I forced myself to jump in, I stumbled over my words and spent the rest of the day replaying what I 'should' have said.

For years I thought this meant I wasn’t fast enough, confident enough, or good enough.

But the truth was simpler: my brain was just running a different operating system.

Unbound Shift

Most people think introversion is about social preference: liking people less, needing time alone, avoiding crowds.

But that's not what's actually happening in your brain.

Brain imaging shows that introverts have stronger connections between thinking and memory regions. When someone asks you a question in a meeting, your brain isn't being slow or hesitant - it's running the information through longer neural pathways, cross-referencing with past experiences, weighing nuances.

Extroverts process rapidly, driven by dopamine - the reward chemical that makes external stimulation feel exciting.

You? You're likely running on acetylcholine, linked to contemplation and calm.

Different fuel. Different processing speed. Different optimal conditions.

This is why you replay conversations later and think of what you should have said. Your brain was still processing whilst the conversation moved on. It's not social anxiety.

It's depth over speed.

This is why small talk feels excruciating but deep conversations energise you; your brain is literally designed for substance, not surface-level exchanges.

This is why a 'quiet work environment helps you think whilst others need music or chatter. You already have higher baseline arousal in your nervous system: your brain is running at a higher idle speed.

Additional stimulation doesn't energise you, it overwhelms your circuits.

None of this is a flaw. It's your operating system.

And once you understand that - truly understand it at a neurological level - everything changes.

You stop trying to fix yourself. You start designing for how you're actually built.

Unbound Step

This week, I want you to notice one moment where you've been judging yourself for something that's actually just your operating system at work.

Maybe it's:

  • Taking longer to respond and calling yourself 'slow'.
  • Needing quiet to think and calling yourself 'antisocial'.
  • Feeling drained after a day of meetings and calling yourself 'weak'.
  • Preferring written communication and calling yourself 'avoidant.'

Just notice it. Name it. See it for what it really is: not a deficit, but a difference in processing.


If you're reading this and thinking "I've been getting this wrong my entire life" you're exactly who I'm creating the Understanding Introversion workshop for.

We're going under the surface and into the neuroscience, the wiring, the patterns that explain why you show up the way you do.

Because here's what I've learned: you can't optimise a system you don't understand.

Once you see your operating system clearly - how your brain actually processes information, why certain environments deplete you whilst others restore you, what your nervous system genuinely needs - you can finally stop blaming yourself and start designing for how you're built.

Self-awareness isn’t the problem. ↓ Hey Reader, You've read the articles. Listened to the podcasts. Taken the personality tests. You know yourself better than most people ever will: You understand that you need boundaries. That you process differently. That you need to protect your energy. So why are you still exhausted? The most common thing I hear from introverts is: “I’ve done the work - why am I still tired?” Because knowing and doing are not the same thing. And somewhere between "I know...

Stop paying the guilt tax! ↓ Hey Reader, The message comes in at 7:43pm. "Do you have 5 minutes tomorrow for a quick call?" You know what 'quick' means. You know you should say yes. You know it won't actually be 5 minutes. You also know that if you say no, you'll spend the entire evening crafting the 'perfect' decline message, then lie awake wondering if you've damaged the relationship. So you say yes. And spend the evening resenting it instead. This is what energy protection looks like when...

If last week was about what you notice, this week is about what you do with it. ↓ Hey Reader, There's a specific kind of panic that happens in meetings. Someone asks a question. You know the answer - multiple answers, actually. Your brain immediately starts running quality control: which one is most accurate? Most relevant? Most useful right now? You're not slow. You're thorough. But while you're refining your response, someone else has already started talking. Thinking out loud. Getting...
