Next Door Neuro

Why do some of our best ideas happen in the shower?
Or on a walk?
Or during a drive?
Or while we're doing something completely unrelated to the problem we're trying to solve?

In this episode of Next Door Neuro - Lab Notes, I explore a fascinating creativity study from researchers at UC Santa Barbara that challenged a common assumption:

When we're stuck, most of us instinctively try to work harder.
We stay at our desks longer.
Think more.
Push harder.

But what if that's exactly the wrong approach?

In this study, participants worked on a creative problem-solving task and were then assigned to different groups.
1. Some kept working.
2. Some rested.
3. Some completed a mentally demanding task.
4. And one group completed a simple, low-demand task that allowed their minds to wander.

Then all the groups went back to the creative problems they had been working on to start. The result?

The mind-wandering group improved their creativity scores by roughly 40%.

Not because they were consciously thinking harder about the problem.

But because stepping away appeared to give the brain room to continue processing information in the background.

In this episode, I explore:
• The surprising findings from the study  
• Why mind wandering may support creativity and insight  
• What happens when we continuously fill every empty moment with stimulation  
• How modern life may be reducing opportunities for our brains to do some of their best thinking  
• A simple strategy for approaching difficult problems more effectively

Importantly:

This isn't an argument against podcasts, music, technology, entertainment, or any other kind of stimulation.

It's a reminder that the brain may benefit from occasional periods of quiet.

Because sometimes the most productive thing you can do isn't to keep pushing.

It's to create enough space for your mind to wander.

Why do so many of us feel like we're constantly falling behind?
Why does slowing down feel uncomfortable?
And why do we often judge ourselves for needing rest, recovery, or space?

In this episode of Next Door Neuro - Lab Notes, I explore an idea that has been sticking with me since my conversation with productivity coach Emily Guerra:

Many of us are treating ourselves like machines. And increasingly, modern life is training us to do exactly that.

More hours.
More output.
More optimization.
More efficiency.
More productivity.

But humans aren't factories, and brains don't work like industrial machines. Our attention fluctuates, our motivation shifts, our energy changes, our creativity ebbs and flows... and recovery following a period of output matters.

In this episode, I explore:
• Why modern culture increasingly equates productivity with value  
• How hustle culture shapes our expectations of ourselves  
• Why humans evolved in rhythms of effort and recovery  
• How productivity slowly becomes identity  
• Why many of us expect things from ourselves we'd never expect from another person  
• And why thriving may require reconnecting with our biological rhythms

Importantly, this isn't about lowering your standards... It's about recognizing that sustainable performance requires recovery.

Because we are biological organisms, not industrial machines.

Why does slowing down sometimes feel uncomfortable… even when we know we need it? 

Why do so many of us feel guilty resting?

And why do moments that should feel restorative feel like we’re falling behind?

In this episode of Next Door Neuro - Lab Notes, I explore something I’m still actively working on myself: I don’t rest well.

Despite spending years studying neuroscience, stress, recovery, burnout, sleep, and performance… there is still a part of me that feels like slowing down means losing opportunities.

And I know I’m not alone. Many of us grew up watching people we admired constantly work. We celebrate busyness, exhaustion, grinding... we say:

“Hustle harder.”
“I’ll sleep when I’m dead.”

But increasingly, I wonder: what if many of us have been trained to associate rest with falling behind?

In this episode, I explore:
• Why guilt around rest is often social conditioning
• How hustle culture shapes our beliefs about productivity and worth
• Why humans evolved in natural cycles of effort and recovery
• How recovery supports learning, creativity, emotional regulation, and sustainable performance
• Why slowing down can feel uncomfortable, and why noticing that matters

Importantly: this isn’t about doing less, it’s about learning how to recover better.

Because recovery isn’t falling behind! Recovery supports thriving.

06:36 – Notice the guilt

Why does it feel harder than ever to focus deeply?
Why do so many of us reach for our phones without consciously deciding to?
And why does stillness sometimes feel strangely uncomfortable?

In this episode of Next Door Neuro – Lab Notes, I explore a realization I’ve been having lately:

I’m slowly losing the ability to direct my own attention.
And I don’t think I’m alone...

Humans evolved in environments filled with quiet.
Downtime.
Stillness.
Boredom.

Those moments created space for thinking, reflection, creativity, and deciding what actually deserved our attention.

But modern life increasingly floods those same systems.
Notifications.
Email.
Social media.
News.

None of these things are inherently bad.

But increasingly, I wonder:
Are we choosing what we pay attention to?
Or is our attention increasingly being chosen for us?

Importantly, this isn’t about eliminating technology.

It’s about learning to notice the pull.
Because attention is trainable.
The brain adapts.

And reclaiming our ability to intentionally direct attention may be one of the most important skills we develop in modern life.

04:43 – Attention shapes our experience
05:40 – Notice the pull
05:55 – Choose what deserves your attention

What if the problem isn’t that we’re lazy, distracted, or undisciplined…

…but that many of the ways we’ve been taught to work are fundamentally misaligned with how the brain actually functions?

For a long time, productivity has meant:
- Doing more.
- Working longer.
- Checking more boxes.
- Pushing harder.

And honestly, for much of college and graduate school, I wore overworking like a badge of honor.

Minimal sleep.
16-hour days.
Constant stimulation.
Always feeling like I should be doing more.

But looking back at that time, I wasn't truly thriving.

I struggled to rest.
To think deeply.
To feel present.
To integrate what I was learning.
And eventually, I realized that productivity and fulfillment are not the same thing.

In this conversation, I sit down with productivity coach and founder of The Productivity Flow, Emily Guerra.

And what I appreciate about Emily’s approach is that she doesn’t just talk about getting more done, she talks about redefining productivity entirely.

We explore:
• Why modern productivity culture increasingly treats humans like machines
• How hustle culture has shaped our relationship with work
• Why rest, stillness, movement, and recovery are essential for focus and creativity
• How smartphones and constant stimulation impact dopamine, motivation, and attention
• Why many of us increasingly outsource emotional regulation to technology
• How small environmental changes can dramatically shift behavior
• And how to build a more intentional and sustainable relationship with work, technology, and ourselves

This conversation isn’t just about productivity.

It’s about attention, energy, presence, meaning, and how we live well inside environments that constantly pull at our brains.

Why do the things we use to reduce stress, boredom, discomfort, or exhaustion so often end up creating more of those exact feelings over time?

In this episode of Next Door Neuro - Lab Notes, I explore one of the most important principles in neuroscience and addiction:

The brain creates the opposite of what you repeatedly use to change your emotional or physiological state.

Using caffeine as a personal example, I unpack why the brain “pushes back,” how repeated relief and stimulation can slowly shift our baseline, and why this idea may help explain everything from addiction… to compulsive phone checking… to why boredom suddenly feels so uncomfortable.

But importantly, this episode isn’t about fear or eliminating pleasure.

It’s about understanding how the brain adapts, and using that knowledge to work with your brain rather than constantly fighting against it.

In this episode, I explore:

• why the brain adapts and pushes back
• how repeated behaviors slowly shape what feels normal
• why modern environments make emotional regulation harder
• practical tools for interrupting automatic patterns
• rebuilding earned reward
• training stillness again
• and how small repeated actions can create meaningful change over time

If your brain fuels your life… what fuels your brain?

Why does addiction still feel like it’s getting worse… despite decades of neuroscience research, treatment programs, and greater awareness than ever before?

In this episode of Next Door Neuro – Lab Notes, I explore one of the most important ideas from my recent conversation with neuroscientist and bestselling author Judy Grisel:

Addiction isn’t getting worse because humans suddenly became weak.

It's likely getting worse because the environment changed dramatically… while the brain stayed largely the same.

And importantly, this conversation isn’t just about drugs anymore.

It’s about modern life more broadly:

• Smartphones
• Social media
• Ultra-processed food
• Gambling
• Pornography
• Endless stimulation
• And constant access to quick relief, reward, and distraction.

In this episode, I explore:

• Why modern life may be becoming increasingly addictive
• “Supernormal stimuli” and evolutionary mismatch
• Why constant access changes behavior
• Why boredom feels increasingly uncomfortable
• Earlier exposure and adolescent brain development
• And the rise of behavioral addictions.

If your brain fuels your life… what fuels your brain?

Why do the things we use to feel better so often end up making us feel worse over time?

In this episode of Next Door Neuro – Lab Notes, I unpack one of the most powerful ideas from my recent conversation with neuroscientist and bestselling author Judy Grisel:

The most important thing we can teach our kids about drugs may not actually be about drugs at all.

It’s about understanding how the brain responds to fast-acting, artificial relief.

Because increasingly, our modern world is built around instantly changing how we feel:
- social media
- pornography
- gambling
- ultra-processed food
- endless stimulation
- and increasingly potent substances

And while legislation and parental oversight matter, I believe we may be underestimating the power of education - especially helping people understand how the brain adapts to repeated artificial relief over time.

In this Lab Notes episode, I explore a framework I’ve found personally helpful:

“There’s no free lunch for your brain.”

The brain isn’t trying to make us happy all the time. It’s trying to keep us balanced. And because of that, the brain adapts to repeated highs, relief, stimulation, and escape - often creating more of the very state we were trying to avoid.

If your brain fuels your life… what fuels your brain?

Why Addiction Is Getting Worse | Judy Grisel

Judy Grisel is a neuroscientist, professor, bestselling author of Never Enough, and a former addict who now studies addiction and the brain. In our full conversation, we explore addiction, dopamine, modern life, and why the brain adapts the way it does.

Why do the things we turn to to feel better so often end up making us feel worse?

In this episode of Next Door Neuro, I sit down with Judy Grisel - a behavioral neuroscientist, professor at Bucknell University, and nationally bestselling author who has spent decades studying addiction… while also living through it herself.

At 12 years old, Judy describes alcohol as: “the solution to a problem I didn’t know I had.”

What followed was a decade-long spiral through substance abuse, homelessness, expulsion from multiple schools, and profound despair - before eventually finding sobriety and becoming a neuroscientist focused on understanding addiction, reward, and the brain.

What makes Judy especially compelling isn’t just her scientific expertise. It’s the combination of deep neuroscience with lived experience.

In this conversation, we explore why addictive behaviors often begin as solutions… how the brain adapts in ways that trap us in destructive cycles… and why addiction may actually be getting worse despite decades of scientific progress.

We discuss dopamine and the brain’s reward system, why modern environments are amplifying addiction risk, how phones, pornography, gambling, and social media hijack the same neural pathways as drugs, and why adolescents may be especially vulnerable in today’s world.

We also dive into evolutionary mismatch, the limits of willpower, the importance of environment, and what recovery taught Judy about meaning, awe, challenge, and real-world fulfillment.

This conversation isn’t just about addiction.

It’s about how the brain learns, adapts, copes, and searches for relief in the modern world.

Most people think they’re not starting because they don’t have enough time, clarity, or confidence… but that’s not the real reason.

It’s that starting feels risky. And your brain is wired to treat that risk (especially rejection) as a threat.

In this Lab Notes episode of Next Door Neuro, I break down why something as simple as asking for a free coffee can feel so uncomfortable, and what that reveals about how your brain processes rejection.

More importantly, I walk through how to retrain that response so you can stop avoiding risk… and start taking action instead.

In this episode:

• Why your brain treats rejection like a threat (and where that comes from)
• How avoidance reinforces fear and keeps you stuck
• Why confidence and clarity don’t come before action - they come from it
• How exposure rewires your brain’s threat response over time
• Why most people never start (and what’s actually driving that hesitation)

Try this:

• Say it out loud: “I’m new to this - if I’m missing something, tell me”
• Create small “rejection reps” (ask for something slightly uncomfortable)
• Measure your reps - not your outcomes
