Brief Overview

In this episode, host Andrea Samadi revisits her enlightening conversation with neuroscientist Friederike Fabritius, focusing on the science behind willpower and the brain’s reward system. Andrea draws on research from previous podcast guests and leading neuroscientists like Dr. Andrew Huberman and Dr. Anna Lembke to provide actionable strategies for strengthening willpower, building resilience, and resetting the brain’s dopamine pathways—providing listeners with science-backed tips applicable to daily life, parenting, and personal development.

Key Discussion Points and Insights

1. Willpower Is Limited – Understanding and Applying Practical Neuroscience

Friederike Fabritius emphasizes that willpower is a finite resource.
- “Willpower is limited. So I try to not waste my willpower on useless things and people and processes that are just not worth it.” — Friederike Fabritius [02:46]
Simplifying life and setting boundaries is necessary to preserve willpower.
- Friederike discusses juggling a high-performance career and parenting, noting that she says no to almost everything outside of her core priorities, ensuring her willpower is used for meaningful work.
- Overcommitting leads to exhaustion and depleted willpower, making productivity and creativity suffer.
Andrea echoes the importance of focusing willpower:
- “Your will gives you the ability to concentrate. It helps you to hold a thought on the screen of your mind or choose thoughts of success over thoughts of failure.” [03:34]
- She shares a personal example: using willpower to write the episode on a Saturday, demonstrating these concepts in real time.

2. The Neuroscience of Willpower – Brain Areas Involved

Key Brain Region: Anterior Mid Cingulate Cortex
- Citing Dr. Andrew Huberman’s research, Andrea explains that acts of willpower, especially doing difficult things, strengthen the anterior mid cingulate cortex, a region tied not only to the exertion of will but also to overall resilience and “the will to live.” [05:10]
- “When you do things you don’t want to do, like adding exercise when you’d rather rest, or resisting foods you enjoy, you’re actually strengthening and growing this part of your brain.” — Andrea Samadi [05:35]
Developing willpower is tied to mental and emotional resilience.
- Athletes tend to have a larger anterior mid cingulate cortex, and challenging oneself can help this brain area grow.
- Maintaining strong willpower is associated with longevity and sustained performance.

Practical Tips to Strengthen Willpower

Practice Deliberate Focus:
- Meditation and exercises like candle gazing help improve concentration and the ability to block distractions.
- “Once you master it, you’ll know that you can sit, focus, and block out the outside world and accomplish anything.” — Andrea Samadi [07:05]
Do Challenging Things:
- Pushing through discomfort or doing tasks you’d rather avoid directly strengthens the willpower centers in the brain.
- The process is gradual but makes willpower more robust over time.

3. The Reward System and Dopamine Regulation

Understanding Reward Systems in Children
- Friederike shares her approach to parenting:
  - “With my kids, I don’t give them everything right away. It’s tempting… but it’s best not to do that because it will throw off the reward system in their brain and they need to learn that they need to work for things to work out.” — Friederike Fabritius [09:28]
- Giving children everything they want, immediately and constantly, can “ruin their prefrontal cortex,” diminishing motivation, patience, and resilience later in life.
Connection to Dr. Anna Lembke’s Research on Dopamine Fasting
- Andrea references Dopamine Nation (Episode 162), highlighting the 30-day dopamine fast as a way to recalibrate overloaded reward pathways.
- She outlines Lembke’s DOPAMINE acronym as a practical tool for resetting your brain’s reward system:
  - D: Data (What are you using, and how much?)
  - O: Objectives
  - P: Problems
  - A: Abstinence
  - M: Mindfulness (Expect to feel worse before you feel better)
  - I: Insight (Learn from abstinence)
  - N: Next steps
  - E: Experiment (Test your new relationship to rewards)
- Andrea shares a personal anecdote: “I used to bribe my kids when they were little with small pieces of chocolate… Not realizing what I was doing to the reward system in their brain.” [11:20]
Key Insight for Parents and Educators:
- Frequent, easy rewards can result in children expecting the same from the world—harming development of motivation and healthy dopamine responses.
- Practicing selective and earned rewards builds stronger, more resilient neural pathways.

Practical Application: Dopamine Reset Challenge

Try removing (or greatly reducing) a habitual reward—sugar, social media, shopping—for 30 days and observe your mood and focus.
“Try going without it for 30 days and observe what happens. Even when moderation is possible, many people find it easier and more freeing just to choose abstinence in the long run.” — Andrea Samadi [12:04]

Notable Quotes & Memorable Moments

Friederike Fabritius on Willpower:
- “Willpower is limited. So I try to not waste my willpower on useless things and people and processes that are just not worth it.” [02:46]
Andrea Samadi on Protecting Energy:
- “I always say to fiercely protect your energy. And beware of what many would call energy leaks that directly impact our Willpower.” [04:49]
Friederike Fabritius on Parenting and Rewards:
- “If you give them everything, you ruin their prefrontal cortex. And then later in life when you're not there anymore, they will expect the same from their surroundings. And that's the difficult.” [09:44]
Andrea Samadi on Personal Change:
- “If there’s something you want to change in your life, try going without it for 30 days and observe what happens.” [12:04]

Welcome Back to season 14 of the Neuroscience Meets Social and Emotional Learning Podcast where we connect the science based evidence behind social and emotional learning and emotional intelligence training for improved well being, achievement, productivity and results using what I saw as the missing link since we weren't taught this when we were growing up in school, the Application Practical Neuroscience I'm Andrea Samadhi and seven years ago launched this podcast with a question that I've never truly asked myself before. And that is if productivity and results matter to us, and they do now more than ever, how exactly are we using our brain to make them happen? And most of us were never taught how to apply neuroscience to improve productivity, our results or our well being. About a decade ago, I became fascinated by the Mind brain results connection and how science can be applied to our everyday lives. And that's why I've made it my mission to bring you the world's top experts so together we can explore the intersection of science and social and emotional learning. We'll break down complex ideas and turn them into practical strategies we can use for predictable science backed results. And as we kick off season 14, I've been revisiting past episodes and reflecting on the incredible insights that our guests shared since we first launched in 2019. So as we dive into this review of our past conversations, know that this review isn't just for you, it's for me as well. I've learned that slowing down helps us to uncover even more wisdom and I'm excited for us to walk this path together for Today's episode number 374. We continue our journey into our mind and our brain with part two of our interview review with neuroscientist Frederica Fabricius, who we covered on Our last episode 373 and her book the Leading Brain. Today we're reviewing a topic that we've covered a few times on this podcast, willpower, that Frederica says is limited and that she tries not to waste on people and processes that are just not worth it.

Willpower is limited. So I try to not waste my willpower on useless things and people and processes that are just not worth it. So. So to a certain degree I try to simplify my life. I have five kids, I have a career, I write books. So in order to manage all of that, I say no to almost everything else. So that is a way, because if I, you know, if I say yes to everything and I do this and I do this and I do this, by the end of the day I'm exhausted. If I then sit down at my desk and try to write on my book, Imagine the result will be a disaster because then my willpower is already depleted and then I just feel like collapsing on my couch. So. So you need to be wise about, you know, not wasting your willpower on things that are not worth it.

A (3:34)

And on episode 294, Beyond Our Five Senses, we explored how to develop and use this important mental faculty of willpower. I find all six faculties of our minds fascinating, but the will is one of my favorites. It's what I'm using right now. So sitting at my desk on a Saturday to stay focused long enough to write this episode, your will gives you the ability to concentrate. It helps you to hold a thought on the screen of your mind or choose thoughts of success over thoughts of failure. With a highly developed will, you can lock into a task, block out distractions, and accomplish what it is that you set out to do. We also looked at willpower on episode 344 recently with the Neuroscience of Building Stronger Minds and Teams, where we explored how grit and mental toughness relate to the new research from Dr. Andrew Huberman. His work shows what happens in the brain when we develop strong willpower. The same kind of strength that we need to overcome adversity. Or as Frederica describes, to sit down and write a book after a long day. This discovery even made one of the world's leading neuroscientists jump out of his chair. And I was right there with him with excitement. I can still remember exactly where I was when I wrote my notes about this on my cell phone notepad when I learned this brain fact. Did you know that there's a part of the brain called the anterior mid cingulate cortex? And it's not just one of the centers of willpower. Scientists believe it may hold the secret to the will to live. And this region increases in size when we do things we don't want to do, like adding exercise when we'd rather rest, or resisting foods that we really enjoy. Or think about the tasks in your day to day life that you'd rather skip over when you do them anyway. You're actually strengthening and growing this part of your brain. Some key points to think about with our willpower. Willpower is limited. Use it wisely. Frederica explains that willpower depletes throughout the day. Simplifying life and saying no to unnecessary things helps to conserve mental energy for what truly matters. And I always say to fiercely protect your energy. And beware of what many would call energy leaks that directly impact our Willpower. We also learned that the will is one of the six faculties of the mind. We covered this originally on episode 294. Beyond our five senses, the will allows us to concentrate, choose thoughts of success, and block out distractions or other limiting thoughts that might occasionally creep into our minds. We looked at the neuroscience of willpower with Dr. Andrew Huberman's research that shows that developing willpower strengthens brain regions involved in resilience and grit. It's actually a part called the anterior mid cingulate cortex that's linked to willpower and even the will to live. And this brain area grows when we do things we don't want to do, like exercising or resisting temptation. Now, let's make it personal. Think about where you use your willpower to stay focused on a task. Like I explained how, I have to use my own willpower to sit at my desk on a Saturday to write this episode. This demonstrates willpower in real time, and it makes the science relatable for all of us. What are some practical tips to develop this faculty of our mind, our willpower? First, practice deliberate focus. Meditation strengthens your will, as does a simple candle gazing exercise, or staring at the flame of a candle until you and the flame become one. And I tried this in my late twenties after a few hours of focus, and then I could finally, in this exercise, feel my attention expand beyond distractions. Developing this faculty takes time and patience. But once you master it, you'll know that you can sit, focus, and block out the outside world and accomplish anything. Another practical tip, do challenging, difficult things that you don't want to do. Every time you push yourself through discomfort, you're strengthening your anterior mid cingulate cortex and in turn your will to actually live. And this part of the brain is larger in athletes and, and it will increase in size with deliberate challenge. And I urge us all to think about this. Do you think you push through challenge or often do things that are difficult? Do you think you have a highly developed willpower? If the answer is yes, keep working on it, strengthening and developing it. Because this part of the brain, Dr. Huberman noted, will keep its size in those people who live a very long time. Moving on to video clip 2. In this second clip, Frederica explains why it's so important to understand the reward system in our brain. She said, with my kids, I don't give them everything right away. It's tempting because you see their happy faces, but it's best not to do that because it throws off the reward system in their brain. They need to Work for things, for it to work out.
