Overview
Rewire is a book about why we do things we know we shouldn't. Richard O'Connor uses neuroscience to explain that self-sabotage isn't a character flaw; it's a brain function. He argues that our automatic self often overrules our conscious self, leading to bad habits like procrastination, overeating, or excessive worrying.
I love this book because it feels both scientific and deeply compassionate. It's not about forcing yourself to have more "willpower." Instead, it’s about understanding how your brain's circuits were built and then learning practical skills, like mindfulness and self-control, to gently build new, healthier pathways. The big promise is that you can train your brain to make better automatic choices.
My Take: The “Two Minds Monitor”
Most summaries of Rewire focus on the science. I wanted to turn it into a practical tool I call the "Two Minds Monitor." As you read this page, I encourage you to think of yourself as an observer of your own thoughts. The goal isn't to judge yourself, but simply to notice which "mind" is in the driver's seat at any given moment.
When I'm about to procrastinate, I pause and ask, "Who's making this decision? My conscious self that wants to get work done, or my automatic self that's avoiding discomfort?" Just asking the question creates a small gap. That gap is where you have the power to make a different choice. This "monitor" approach helps me apply the book's ideas in real-time, instead of just understanding them in theory.
Key Takeaways
You Have Two Minds in Conflict
The core idea is that we have a conscious self (rational, thoughtful) and an automatic self (habitual, emotional, and fast). Self-destructive behaviors happen when the automatic self takes over. Understanding this conflict is the first step, because it shifts the problem from "I'm lazy" to "My automatic brain is running an old program."
Bad Habits Are Physical Circuits
O'Connor explains that bad habits have a physical presence in our brains as well-worn neural pathways. This is why they feel so hard to break. The good news is the brain is "plastic," meaning it can change. Every time you practice a new, healthy behavior, you are physically building a new circuit and making it easier to choose next time.
Mindfulness Is the Bridge
Mindfulness is the key skill for bridging the gap between your two minds. It's the practice of observing your thoughts and feelings without immediately acting on them. This creates a pause, giving your conscious self a chance to step in and make a better decision rather than letting the automatic self react based on old habits.
Willpower Is a Skill, Not a Trait
The book taught me that willpower isn't something you either have or don't. It's a skill you can build with practice, like a muscle. Instead of waiting for motivation, you can take small actions that train your nervous system and make self-control easier over time.
Chapter-by-Chapter Summary (Short & Simple)
Part 1: The Automatic Brain
In the first part, O'Connor introduces the concept of our two brains. He explains how the automatic brain is designed for efficiency, running on habits to save energy. But sometimes, these old habits no longer serve us, leading to procrastination, addiction, and other self-defeating behaviors. This section helped me see my bad habits as outdated software, not personal failings.
Part 2: The Conscious Brain
Here, the focus shifts to the conscious self, the part of you that can think, plan, and reason. O'Connor describes how skills like self-awareness and mindfulness can strengthen this part of the brain. He makes it clear that the goal isn't to eliminate the automatic brain, but to train it to work in harmony with your conscious goals.
Part 3: The Art of Rewiring
This is the most practical part of the book. O'Connor lays out specific techniques for rewiring your brain. He covers how to "un-practice" bad habits, how to handle the fear and guilt that often come with change, and how to use mindfulness to interrupt impulsive behaviors. This section is like a user manual for making lasting change.
Part 4: Putting It All Together
In the final section, O'Connor discusses common issues like depression, anxiety, and addiction through the "two minds" lens. He provides specific advice for each, showing how understanding the brain's wiring can offer new paths to healing. It reinforces that these struggles are often the result of a brain stuck in a self-destructive loop, and that rewiring is possible.
Main Concepts
The Two Minds in Everyday Life
Once I started looking for the two minds, I saw them everywhere. My conscious mind knows I should go to the gym, but my automatic mind drives me to the couch after a long day. My conscious mind wants to save money, but my automatic mind clicks "buy now" for instant gratification. This constant tug-of-war is the central problem Rewire helps you solve.
Automatic Self
- Acts on impulse and emotion
- Follows old, ingrained habits
- Seeks immediate comfort
- Operates without conscious thought
- Can lead to self-sabotage
Conscious Self
- Uses reason and logic
- Focuses on long-term goals
- Can make deliberate choices
- Requires effort and attention
- Can train the automatic self
Neuroplasticity: Your Brain Can Change
The most hopeful concept in the book is neuroplasticity. For a long time, scientists thought the brain was fixed after childhood. We now know it's constantly changing in response to our experiences and thoughts. This means you are not stuck with the brain you have today. By intentionally practicing new behaviors, you are physically reshaping your brain to support your goals.
How to Apply the Ideas This Week
This isn't just theory. Here are a few small actions you can take this week to start rewiring your brain, using my "Two Minds Monitor" approach.
- Identify one automatic habit. Pick one small, self-defeating habit you want to change (e.g., checking your phone when bored, eating a snack when not hungry).
- Activate your "monitor." When you feel the urge to do that habit, just pause and ask: "Is this my conscious self or my automatic self talking?" Don't judge, just notice.
- Practice a 1-minute pause. Before giving in to the urge, wait for just 60 seconds. This tiny delay is an exercise for your conscious brain, strengthening its ability to step in.
- Choose a new, tiny action. Instead of the old habit, do something else that is very small and easy. If you want to stop procrastinating, just open the document. If you want to eat healthier, just drink a glass of water first. This starts building a new neural pathway.
Memorable Quotes
“People believe they lack will power, but will power is not something you either have or don't... Instead, it's a skill, like tennis or typing.”
“Each time we engage in a bad habit, we make it more likely we'll do it again in the future.”
“Most self-destructive behavior is the result of the fact that we have two minds that don't communicate very well.”

Final Thoughts
For me, Rewire was empowering because it took the shame out of my bad habits. I stopped seeing myself as "undisciplined" and started seeing a brain that was just running on old software. This shift in perspective made all the difference.
Using the "Two Minds Monitor" has become a daily practice. It doesn't mean I never make impulsive choices, but it means I'm aware of them far more often. That awareness is the first and most important step in rewiring your brain. This book doesn't just give you information; it gives you a practical, science-backed way to become a better version of yourself, one conscious choice at a time.
