Your Brain Has Three Settings. Here Is How to Stop Overthinking
A two-word message arrives from your boss: “Can we talk?”
No context. No agenda. Within seconds your mind has written a story. Maybe you are in trouble. Maybe you are about to be rewarded. Maybe it is nothing at all. Whichever story wins will shape the next hour of your day, and if you lead people, it will shape theirs too. Multiply that moment across a thousand employees and you are looking at the real engine of workplace culture: not the values on the wall, but the stories running in people’s heads.
I have spent years watching this engine misfire. In my McKinsey years, looking closely at how leaders were really operating, I found that ~70-80% of people were operating from a fight-flight-freeze nervous system most of the day. Constantly on, constantly scanning, but most of them had no idea they were doing that including me.
My friend Due Quach, founder of Calm Clarity, has built an amazing way to see what is happening in those moments, and more importantly, to change it.
Why the brain never stops talking
Due’s own path to this work was anything but academic. Her family fled Vietnam when she was a baby. She grew up in inner-city Philadelphia, fought her way to Harvard and Wharton, and built a career in consulting and private equity. By 2012 she had the credentials and the income, and she was working alongside people who were, in her words, “just so toxic to be around, no matter how much money they had.” She walked away, bought a one-way ticket to Dharamsala, and went looking for the inner peace she had never been taught.
What she brought back is a practical map of the default mode network, the brain system that switches on whenever we are not focused on a task. It narrates, predicts and it rehearses conversations and replays mistakes. As Due puts it, researchers realized “the brain never really rests.”
That network is not the enemy. It evolved to help us navigate relationships and plan our lives. The problem is that it is easily scattered, and it defaults to whatever we have practiced most. Research bears this out. A Harvard study of more than 2,000 adults by Matthew Killingsworth and Daniel Gilbert found that people’s minds wander nearly 47% of the time, and that a wandering mind is reliably a less happy one.
Brain 1.0, 2.0, 3.0: which one is running you?
Due describes three settings for the default mode network.
Brain 1.0 is the threat system. It keeps you alive. Under pressure it catastrophizes, armors up, withdraws, and transmits fear to everyone nearby. Due calls it the Inner Godzilla.
Brain 2.0 is the reward system. Driven by dopamine, it chases goals, status, validation and control. It is restless and impatient. It says yes to everything the boss wants because pleasing the boss feels safe. Due calls it the Inner Teen Wolf.
Brain 3.0 is the Inner Sage. Calm, curious and connected, it sees the bigger picture and the long term. It is the last system to fully develop, often not until our mid-to-late twenties, which is exactly why the first two become so entrenched.
Run the “Can we talk?” message through each. Brain 1.0 hears “I’m getting fired.” Brain 2.0 hears “I’m getting promoted, drop everything.” Brain 3.0 replies, “Here is what I have on my plate. Here are times that work. Let me know if it is urgent.”
Same message. Three completely different days.
I once left a team member a voicemail on a Saturday simply to check she was okay after a hard week. When she called back, she told me her heart had jumped when she saw my number. “I’ve never had anybody do that,” she said. Her brain had gone straight to what I must want from her; that is not a character flaw, that is Brain 1.0 doing its job.
This is why I told Due, “The default doesn’t have to be one state. You can train it to be in different states.” It is the premise of our REWIRE program too: neurons that fire together wire together, and the mode you practice becomes the mode you live in.
How to get out of survival mode (it is not only for people in crisis)
It is tempting to think Brain 1.0 belongs to people living through obvious hardship. Due first built Calm Clarity for high school students in under-resourced Philadelphia neighborhoods, and many of the executives who supported it saw it as a charity program for kids in need. Then the pandemic arrived, and those same leaders found themselves living in Brain 1.0 “on a constant, chronic, daily basis.”
Big-T trauma is not required. The daily news cycle, the relentless pace, a dozen small humiliations in a quarter: micro-traumas add up, and the nervous system keeps score.
Here is the part leaders miss. Brain 2.0 is still a survival state. The hard-charging, goal-chasing, why-isn’t-this-moving-faster mode feels like performance. It is actually coping. Due borrows Lisa Feldman Barrett’s idea of a body budget: the body funds survival first, reward second and wisdom last. With a full battery, Brain 3.0 is easy. As it drains, you slide into Brain 2.0, pushing and grabbing for control, and then into Brain 1.0, where there is no cognitive capacity left to solve problems.
That’s where a lot of leaders end up doing things they regret,” Due told me. “It’s because they pushed themselves and everyone too far.”
The stakes scale with the role. In her words:
When leaders are going about making decisions in Brain 1.0, it impacts hundreds of thousands of people.”
Emotions travel down the hierarchy. Sigal Barsade’s research on emotional contagion showed that a single person’s mood measurably shifts the mood, cooperation and performance of an entire group. A leader in survival mode does not stay there alone.
How to stop overthinking: talk to your default mode network
Due’s first attempt at meditation failed. Her mind raced and she decided meditation was not for her. Years later, after studying the neuroscience, she tried again with a different instruction. “I just had bad instructions,” she said. “If someone tells me to clear my mind, that is impossible.”
I could not agree more – your brain never stops racing. The only person whose brain has stopped racing is the person who’s dead. The goal was never silence. It is awareness.
So Due teaches people to watch the default mode network instead of fighting it. Is it planning lunch? Rehearsing a meeting? Circling the same worry? If it keeps returning to one thing, that stickiness is a signal. Then comes the part most people miss: “What people don’t realize is you can actually talk to your default mode network.” You can give it feedback. For example, you can say “This isn’t helpful right now, help me prepare for this presentation.” Treated this way, the inner narrator starts to behave like an inner coach.
The neuroscience supports the approach. Judson Brewer and colleagues at Yale found that experienced meditators showed markedly less activity in the core regions of the default mode network, and stronger connections to the areas responsible for self-monitoring. Awareness changes the network itself.
Nervous system regulation starts in the body
Due’s second practice is a quick body scan, because the body usually knows before the story does. Brain 1.0 shows up as contraction: a clenched jaw, tight fists, the urge to become invisible. Brain 2.0 shows up as rigidity and restlessness, the impatience of “why can’t this be done now?”
Catch the signal and you get a choice to breathe, walk etc. Take the break before the decision instead of after it. This is the practical heart of nervous system regulation, and it is why I see recovery not as a reward for finishing the work, but as the thing that keeps your best thinking online.
Underneath both practices sit the four systems Due draws from Daniel Goleman and Richard Davidson’s review of contemplative science: attention, meta-awareness, resilience and connection. They are trainable, and they compound. Due is careful to add that no single practice suits everyone. Assess first, then pick the practice that fits your wiring.
Workplace wellbeing as a team ritual
A practice that lives only inside one person rarely changes a culture. The most compelling part of our conversation was what happened when a whole team adopted it.
Eric led the budget and transformation teams at a Philadelphia mass transit authority. Due worked with them for six months, giving them a shared language for the three brains and data on their patterns. The results moved “from red to green.” When a colleague snapped, people stopped taking it personally and recognized a stressed human in Brain 1.0. When a fiscal crisis hit and Eric was promoted to interim CFO, going from a team of roughly 20 to around 1,000, he told Due he would have “collapsed in Brain 1.0” without it.
Their rituals were simple. They celebrated wins. They took a few breaths before meetings. They opened with a short set of wishes for each other: may you be happy, healthy, safe and peaceful. As Due explained,
Instead of seeing this person as an obstacle, you see this person as a human being.”
For leaders who find that last one too soft, I offer a reframe. Every organization serves someone. Picture your team, your customers and the community whose lives you are trying to improve, and wish them well. It is a reminder that you are all on one big team. Oil and gas companies open meetings with safety moments. Why can’t we open with a mindfulness moment?
This is what workplace wellbeing looks like when it stops being a perk and becomes part of how work gets done.
Where to begin
The next time a message lands and your stomach drops, try Due’s simplest exercise. Write down what Brain 1.0 is saying. Then Brain 2.0. Then ask what Brain 3.0, your wisest self, would do. Due ends her own hard days with one question: “What does my higher self want me to do?”
Choose that voice once today, and again tomorrow, that is how a default changes.
