Why is it so hard to start something new… even when you know it would be good for you?

In this episode of Next Door Neuro, I sit down with Mark Heckmann - multi-business founder and entrepreneurial coach - to explore what actually gets in the way when we try to start.

Mark has built companies across industries ranging from robotics and agriculture to AI and consulting. But what makes him especially interesting isn’t just what he’s built... it’s how he thinks.

He started with almost no resources… bartering websites for things like pizza… and built momentum by taking action before feeling ready.

Now, he helps others do the same.

In this conversation, we break down:

• Why most people never take the first step,
• How your brain interprets risk and rejection
• What actually changes when you stop waiting for certainty and start taking action.

We also get into one of the most powerful mindset shifts for me personally: reframing rejection not as failure, but as data. Because you’re not even in the game until you’ve heard 100 “nos.”

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

In this episode:
• Why starting feels so difficult (even when the idea is clear)
• How your brain interprets risk, rejection, and uncertainty
• Why waiting for certainty keeps you stuck
• How to reframe rejection as useful data
• The role of repetition in building confidence
• Why autonomy changes how you think about work
• How to start something without massive resources
• The difference between planning and actually doing
• Why most people quit before they’ve even really started

Most of us think that just getting outside is enough.

But if your attention is on your phone, your brain is still operating like you’re indoors… and you’re missing a lot of what nature is actually doing for you.

In this Lab Notes episode of Next Door Neuro, I break down how your phone may be undermining the benefits of being outside - and why presence, not just location, is what actually matters. I explore why nature helps reduce stress, restore attention, and quiet rumination - and how those benefits can be lost if your attention is somewhere else. I also share two simple ways to start getting more out of the time you’re already spending outside.

In this episode:

• Why being outside doesn’t automatically reduce stress
• How your phone keeps your nervous system “on”
• What “soft fascination” is, and how it restores attention
• How nature helps quiet anxiety and rumination
• Two simple ways to get more out of time you’re already spending outside

Try this:

• Stand still longer than feels normal
• Pause before reaching for your phone

Being Outside Isn’t Enough - conversation with Sarah Nielsen

https://www.youtube.com/watch?v=OpXhaC7JQK0&t=10s

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

What if the reason you still feel stressed, scattered, or disconnected isn’t because you’re not spending enough time outside… but because you’re not actually experiencing it?

In this episode of Next Door Neuro, I sit down with Sarah Nielsen, M.Ed, NBC-HWC, a health and outdoor educator and board-certified wellness coach, to explore why simply being outside isn’t always enough, and what it actually takes for nature to meaningfully impact your brain, body, and well-being.

We talk about how modern life has shifted us indoors, how screens now follow us everywhere, and why so many of us are technically “outside,” but still mentally somewhere else.

Sarah shares how our phones are changing the way we experience nature - turning special moments into something we capture instead of something we actually feel - and what we’re missing as a result.

We also explore the science behind why nature helps us feel better, from stress reduction and attention restoration to the sensory and emotional experiences that screens simply can’t replicate.

One of the biggest takeaways from this conversation:

You don’t necessarily need more time in nature.
You need more presence when you’re there.

Sarah also introduces something critical: the idea of “sips of nature” - small, consistent moments of outdoor exposure that can meaningfully improve your stress, focus, and overall well-being.

Key Topics:

• Why 93% of Americans spend most of their time indoors
• Why being outside isn’t enough if your attention is elsewhere
• How phones are changing our experience of nature
• What we miss when we’re not fully present outdoors
• Stress Reduction Theory & Attention Restoration Theory
• Why nature improves focus, mood, and brain function
• “Sips of nature” vs. all-or-nothing outdoor thinking
• Intrinsic vs. extrinsic motivation (and social media’s role)
• Why nearby nature and your “wild home” matter most
• Simple ways to bring nature into daily life

Most of us are using AI the same way:

Ask a question.

Get a great answer.

Maybe go a little deeper…

And in the moment, it feels incredibly productive.

Clear. Insightful. Like you’ve really learned something.

And then a few hours later… it’s gone.

Why does this happen?

In this Lab Notes episode, I break down the brain science behind why learning with AI often doesn’t stick, even when it feels like it should.

There are a few key mechanisms at play, including cognitive offloading (outsourcing the work of thinking), the difference between recognizing and generating information, and the lack of “desirable difficulty” that our brains actually need to learn. We also explore the fluency illusion - why something can feel clear in the moment without being deeply understood - and how instant answers may be disrupting dopamine-driven learning.

AI isn’t the problem. But the way we’re using it may be eroding how we learn. Over time, that creates a gap between what feels like progress… and what we can actually use in our day-to-day lives.

In this episode, I also share two simple ways to learn with AI instead of just consuming it:

• Think First, AI Second

• The No-Look Test

The goal isn’t to use AI less, it’s to use it in a way that actually builds your brain.

What happens when the way we get answers starts to change how we think?

In this episode of Next Door Neuro, I sit down with Lori Robbins, Head of AI Strategy at Denison University and founder of Herizon AI, to explore how AI is reshaping not just how we work, but how we learn, reflect, and relate to other people.

We start with Lori’s experiment stepping away from AI for a week, and what it revealed about how quickly these tools have become embedded in our daily lives. From the frustration of going back to traditional search, to the deeper connection that comes from turning back to human experience, the conversation highlights both what AI gives us and what it might be taking away.

We explore why AI can feel like a “thought partner,” where that experience breaks down, and how instant answers may be altering the way we process, understand, and retain information. Lori also shares how these systems actually work, why they tend to agree with us, and what it means to use AI in a way that supports - rather than replaces - our own thinking.

We also discuss the growing role of AI in education, mental health, and companionship, and what it means for a generation growing up alongside this technology.

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

In this episode:

• Lori’s AI-free experiment and what it revealed
• Why AI feels conversational, and why that matters
• The difference between AI-generated insight and human experience
• How instant answers can create the illusion of understanding
• The “Yes-Bot effect” and why AI often agrees with you
• AI, critical thinking, and the next generation
• The opportunities and risks of AI in mental health and connection
• Data privacy and what we share with AI tools

Most of us start our day the same way:

Phone.

Notifications.

A quick scroll.

Within minutes, we’ve had dozens of tiny dopamine hits…

And somehow, the rest of the morning feels flat.

Why?

In this Lab Notes episode, I break down the neuroscience of dopamine - and why not all dopamine is created equal.

There’s a critical difference between earned dopamine and unearned dopamine, and understanding this difference can completely change how you think about motivation, energy, and focus in your daily life.

We live in a world filled with instant rewards (social media, ultra-processed food, constant notifications) and over time, these “easy” dopamine hits can actually reduce your baseline motivation and make meaningful work feel harder.

But there’s a better way!

In this episode, I cover:

• What dopamine actually does (it’s not just “pleasure”)
• Why “unearned rewards” can drain motivation over time
• How modern life is pushing us toward low-quality dopamine
• Why effort, challenge, and discomfort lead to better outcomes
• How to rebuild motivation through “earned rewards”

3 practical ways to rebalance your dopamine:

1. Create space between effort and reward
2. Add one daily “earned reward” anchor
3. Reduce one source of constant, easy dopamine

The goal isn’t less dopamine.

It’s better dopamine.

What if the reason so many of us feel off is because life has become too comfortable, too controlled, and too disconnected from what our brains actually need?

In this episode of Next Door Neuro, I sit down with Richard Campbell, founder of 10Adventures, to explore why so many people are drawn to adventure, nature, and challenge - and why these experiences may be far more important for our mental health, perspective, and sense of meaning than we realize.

We discuss why outdoor adventure isn’t about dramatic, life-changing epiphanies, but instead about small shifts in how we think, feel, and live. Richard shares what he’s learned from helping thousands of people step outside their normal routines, and we explore how challenge, movement, nature, and disconnection from modern life can help us feel more like ourselves again.

We also dive into evolutionary mismatch, the hidden psychological cost of modern convenience, why walking helps solve problems, how adventure can strengthen relationships, and what it means to build a life around what actually matters.

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

In this episode, we cover:

• Why people crave adventure during major life transitions
• The simplicity people rediscover when they step away from daily life
• Why meaningful change tends to happen gradually, not all at once
• How modern environments may be pulling us away from what our brains are wired for
• Why walking, hiking, and time outdoors support stress reduction and clearer thinking
• The connection between challenge, discomfort, and feeling more alive
• How shared outdoor experiences can strengthen relationships
• Richard’s decision to leave a successful career at 40 to pursue a more meaningful path
• Why clarity often comes from stepping away rather than pushing harder

Most of us have a constant voice in our head: questioning, criticizing, and second-guessing everything we do.

What if you could change your relationship with that voice, and see it for what it really is?

In this Lab Notes episode, I reflect on my conversation with Dawn Wecker (from the Dawnversations Podcast) and break down the neuroscience behind negative self-talk, rumination, and the identity loops that shape how we see ourselves.

You’ll learn:

• Why your brain is wired to focus on negative thoughts
• How this drives rumination
• Why modern life makes all of this worse
• How repeated thoughts become our identity over time

And most importantly, I’ll walk you through four simple techniques you can use immediately to create distance from that inner voice and take back control.

This isn’t about “just thinking positive.” It’s about understanding your brain, and learning how to work with it instead of against it.

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

Try this today:

The next time that voice shows up, don’t fight it.

Just say: “I’m having the thought that…”

That one shift can put the voice in its place.
