What Is Your Primitive Brain? (And Why It's Running Your Week)

I want to talk to you about something that is going to explain a lot.

Like, a lot a lot.

Why you can't stop scrolling at 10pm even though you're exhausted, why you pour the wine before you've even decided to pour the wine, why you know you should go to bed early and somehow don't.

This is a brain problem – and more specifically, it's a primitive brain problem.

So, what is your primitive brain?

It's the part of your brain you needed thousands of years ago, when we lived in caves and were threatened daily by lions and tigers. It kept us alive, it kept us safe, and it was absolutely brilliant for that particular era of human existence.

Now we live in a world with Uber Eats, air conditioning, and maybe the occasional ant infestation in the kitchen — ugh — but our primitive brain is still working just as hard as it ever did, still scanning for threats, still trying to protect us, still running the show.

It has three motivations, and only three: avoid pain, seek pleasure, and conserve energy.

Here's what that looks like in your actual life in 2026:

Avoid pain? Work like a dog on 30 tasks a day to make sure your boss or your clients never, ever get mad at you.

Conserve energy? Do not jump on the trampoline with your kid — you're already exhausted, and frankly, you cannot cope with weeing yourself right now.

Seek pleasure? Pour a wine the second 5pm hits. But I'm cooking dinner, your brain reassures you, it's my ritual. Sure it is.

Sound familiar? That's your primitive brain, doing exactly what it was designed to do — just in a world it was never designed for.

And here's the thing. There's another part of your brain, your prefrontal cortex, that is more evolved, more considered, and genuinely trying to help you build the life you actually want. It's the part that can think about your own thoughts, set goals, plan calmly, and keep you in a really good state.

But your prefrontal cortex asks something of you that your primitive brain absolutely hates: seek discomfort, use energy, and delay pleasure. Set the big goal. Get up early. Exercise three times a week. Don't eat that. Be a better person.

And that right there (that push and pull between the two parts of your brain, that feeling of knowing better but never quite doing better) that is what I work on with every single client I have ever coached.
