The Prehistoric Brain in the Modern World
How to Get Unstuck When Your Brain is Holding You Hostage
You are not the problem. Your brain is doing exactly what it was built to do. It is scanning for threats, conserving energy, finding patterns, and protecting you from anything that feels uncertain or dangerous. The fact that it is doing this in response to a critical email instead of a predator does not make the response any less real. Your brain does not know the difference.
This book explains what is actually happening inside you, and why understanding it changes everything.

Who this book is for
This book is for anyone who has ever felt like their brain is working against them. The people who overthink, over-prepare, replay conversations, say yes when they mean no, or stay stuck in patterns they fully understand and cannot seem to change. The explanation you were given, that you need more discipline, more willpower, more commitment, is wrong. This book gives you the right one.
What the book covers
Your inner caveperson
Inside you is a brain shaped by millions of years of survival in a world that no longer exists. That brain is still running its original software.
Four facts about your brain
Your brain is designed to keep you safe, conserve energy, construct its own version of reality, and store memories shaped by emotion.
Ancient survival traits in modern life
Fight, flight, or freeze. Negativity bias. Fear of the unknown. Pattern recognition that sees threats that are not there. These traits kept your ancestors alive. In your modern life, they keep you stuck.
What you can actually do
The book does not end with insight. It ends with a framework for working with your nervous system rather than against it, built on what the biology actually requires for change.
"Beneath everything is a scared, vulnerable human with a brain that is just trying, every moment of every day, to keep you safe."
