Bountifull Podcast

So much of the health and wellness conversation starts with what we should do: eat differently, train more, sleep better, follow the plan and somehow find the discipline to keep doing it.
But what if the plan isn’t the first thing we need to look at?
In this conversation with Brittany McNabb, we go underneath the habits and routines to explore what might actually be driving our behaviour. Brittany explains why our nervous system, identity, beliefs and capacity all shape our ability to create lasting change — and why pushing harder can sometimes make things worse when we are already overloaded.
We talk about chronic stress and functional freeze, why behaviours we call “self-sabotage” may actually be helping us cope, and how small, repeated actions can gradually build greater safety, self-trust and capacity.
We also explore dopamine and modern life: why constant stimulation can leave ordinary experiences feeling flatter, why our attention can become harder to direct, and what we can do to create more space and less input.
Before we get into the practicalities of food, nutrition and training, this conversation asks us to understand the system those plans have to land in.
Because change becomes much easier when we stop fighting ourselves and start understanding what we actually need.

Episode Highlights
Why knowing what to do doesn’t necessarily mean we have the capacity to do it

What nervous system regulation actually means — and why it isn’t about being calm all the time

Why some behaviours we call “self-sabotage” may actually be coping strategies

How chronic stress can show up as functional freeze: “I want to, but I can’t”

What dopamine actually does and how constant stimulation can affect motivation and satisfaction

Why Brittany recommends protecting the first 30 minutes of your day from input

How small, repeated actions can rebuild safety, self-trust and capacity

Why sustainable wellness should expand your life rather than consume it

Alliv Samson has spent more than a decade building Kami, the education company she co-founded at university, into a global platform used by more than 70 million people. Along the way came enormous growth, motherhood, a partial exit and the chance to experience what life looks like when some of the things you once worked so hard for finally arrive.
And perhaps surprisingly, Alliv’s biggest lesson is not about ambition or achievement. It is about peace.
She talks about learning to be happier with what she has, kinder to herself when things do not go to plan, and more discerning about what deserves her energy. Her upbringing taught her that difficult things happen and that, somehow, you find a way through. Success has taught her something different: that you also have to remember to enjoy your life while you are living it.
For Alliv, that now means protecting her relationships, nurturing her creativity, making room for curiosity and side quests, and no longer allowing work to occupy every corner of who she is.
A thoughtful conversation about what success can teach us, what it cannot give us, and why a bountiful life might ultimately be much simpler than we think.

In This Episode
What success has taught Alliv about what actually makes life feel rich

Why peace of mind matters more to her now than wealth or achievement

How growing up in the Philippines shaped her resilience and belief that there is almost always a way through

What she wishes she had done differently while spending more than a decade building Kami

Why learning to worry less and be kinder to yourself has changed the way she lives

How to know when one goal, career or ambition is taking up too much of your life

Why creativity, curiosity and “side quests” can make us more fulfilled, not less focused

The importance of making time for the people you love before life forces you to

Why stepping away can sometimes be exactly what you need to find your energy and perspective again

How success shifted Alliv’s focus from achievement towards contribution, relationships and what she wants her life to mean

Something new is beginning at Bountifull.
For more than two years, I’ve been having conversations with people around the world exploring a simple question: how do we actually live a good life?
More than 80 conversations later, I’ve learnt an enormous amount. Along the way, I’ve started to see themes and ideas emerging across conversations with people from completely different perspectives, backgrounds, countries, identities and professions.
There’s enough there that I’ve decided to turn some of what I’ve been learning into a book. I’ve begun writing it, and at the moment I’m thinking a lot about the conditions that make a bountiful life possible. What creates those conditions? What crowds them out? Why are so many of us encouraged to build lives that look good on paper, but don’t necessarily feel particularly good to live in? And what might we do differently?
For the next few months, I want to give myself more room to write and think. Bountifull Podcast episodes will move to being published fortnightly on Sunday's at 10am NZT. 
In between, you'll still be hearing from me, I’ll be writing to you every week by email, sharing what I’m learning, the questions I’m exploring or wrestling with, and probably some of what happens as the book starts to take shape. If you don’t already get those emails, please join below. Lots of people tell me that they like my emails! 
I’d also really love to get to know more of you a little better. After all, I think a bountiful life is something we build with other people, not on our own.
If there’s something you’ve heard in a Bountifull episode over the past couple of years that has stayed with you, something you learnt, something that made you realise something, changed your mind, or was simply really interesting, tell me.
You can leave a comment on the episode below or send me a message, I've linked my contact form below. I read everything I get and I reply. I genuinely love hearing from you and the Bountifull Community around the world.

In this episode, I sit down with sociologist and demographer Paul Spoonley to explore how the population changes already underway could shape the life you’re able to build in the decades ahead.
We’re living longer, having fewer children, becoming more culturally diverse and concentrating more of our populations in major cities. Paul explains why those shifts matter to you, from the future of retirement and healthcare to regional communities, migration and the number of people available to work.
We also look at the choices underneath the statistics. Why are fewer people having children? How much is the cost and structure of modern life narrowing those choices? What makes you stay where you are or move elsewhere? And what happens when the systems built for one generation no longer fit the next?
Paul argues that demography is destiny. Many of these changes can already be anticipated, which means the bigger question is what you choose to do with that knowledge.
We talk about retirement, taxation, intergenerational fairness, the changing nature of work and what you might need to think about now as you prepare for a very different future.

Episode Highlights
🌍 Why Demography Matters to Your Life: How ageing populations, falling birth rates and migration quietly shape the choices available to you and the life you’re able to build.
👶 Why Fewer People Are Having Children: How housing, cost of living, careers and changing expectations are influencing one of life’s most personal decisions.
💰 Rethinking Retirement: What longer lives and fewer working-age people could mean for superannuation, healthcare, taxation and how you prepare financially for your future.
🏡 Where You Choose to Live: How work, affordability, family, friendship and quality of life create a “centre of gravity” that can influence whether you stay, move or build a life somewhere new.
🤝 The Changing Contract Between Generations: Why younger generations are entering a different economic reality, and what questions that raises about fairness, wealth and who pays for the systems we rely on.
🔮 Preparing for a Future We Can Already See Coming: Why understanding demographic trends now can help you make better decisions about work, money, family, community and the decades ahead.

This week on Bountifull, I’m joined by Brittany McNabb for the first in a four-part series exploring health, wellbeing, food and fitness from a very different angle.
Brittany is a personal trainer with a background spanning psychology, business, psychotherapy, nutrition, meditation and behaviour change. Her work starts from a simple idea: lasting change is about far more than calorie deficits, macros or what you do at the gym.
Brittany describes much of the health and fitness industry as focusing on the tip of the iceberg: the habits, meal plans, macros and training programmes we can see. Her work goes underneath that, into our identity, beliefs, nervous system, conditioning and capacity for change. Because the goal isn’t simply to achieve a result. It’s to find an approach to health that you can actually sustain — one that builds your strength, energy and capacity for life rather than requiring you to make your life smaller to maintain it.
But first, we go back to Brittany’s own story. We talk about growing up as a Jehovah’s Witness, severe bulimia and anorexia, shame, perfectionism, miscarriage, birth trauma, significant weight gain and the journey that eventually led her to lose 40 kilos, rethink her relationship with health and build a business helping thousands of women create lasting change.
It’s the story behind the work, and the foundation for everything we’ll explore next.

Episode Highlights
Why lasting health change is about far more than calories, macros and exercise

How shame, perfectionism and not feeling “good enough” can shape our behaviour

Why our relationship with food is often about comfort, belonging, control and more than nutrition

How to pursue health and body goals without making your life smaller in the process

How to separate what you genuinely want from what you’ve been conditioned to want
