Financial Joy vs The Wealth Habit
Since we announced our new book, The Wealth Habit, the single most common question we’ve had in our DMs, our community, at events, by email, is this:
“I’ve already read Financial Joy. Do I actually need The Wealth Habit too?”
And from others:
“I haven’t read either. Which one do I start with?”
Both books are by us. Both are published by Quercus (an imprint of Hachette).
Both are about money, wellbeing and designing a life you love.
We get why someone looking at both covers might think: same authors, same topic – what’s the difference?
So we wanted to sit down and give you the most thorough, honest answer we can.
No marketing fluff. Just the truth about what each book does, who it’s for, and why we wrote both.
Financial Joy vs The Wealth Habit: The Simplest Way to Understand the Difference
If we had to capture each book in a single sentence:
Financial Joy is the reset. The Wealth Habit is the system.
Financial Joy is the emotional and practical reset that helps you get unstuck and finally feel in control of your money.
The Wealth Habit is the system that makes wealth effortless, inevitable and sustainable for life.
Or as we put it in the introduction to The Wealth Habit:
“Start with joy. Stay with habit. Finish with freedom.”
Financial Joy is where you start. The Wealth Habit is how you stay. Freedom is where you end up.
Why We Wrote Each Book
Financial Joy was published in 2024. It was our debut – the book we’d dreamed about for years.
We wrote it because when we asked our communities how they felt about money (especially post Covid), the same words kept coming up: stressed, worried, frustrated, anxious, overwhelmed.
We knew that feeling. We’d lived it. We wanted to write the book we wished we’d had when we were in that place – a practical ten-week plan to banish debt, grow your money and unlock financial freedom, with joy at the centre.
Mary: When we were writing Financial Joy, I kept thinking about the women in our community who were carrying so much silently, e.g. managing households, juggling work, worrying about money at 11 pm, but never feeling like they had “permission” to take control.
I wanted that book to be the friend who says: You’re allowed to sort this out, and here’s exactly how.
Financial Joy went on to become a Sunday Times bestseller.
We’ve received thousands of messages from readers who cleared debts, started investing for the first time, had money conversations with their partners and completely shifted how they felt about money.
That means the world to us.
But then something interesting started happening.
Readers who’d gone through Financial Joy – who’d sorted their budgets, tackled their debts, opened their ISAs – kept coming back and asking:
“Okay, I feel in control now. But how do I make this stick? How do I make wealth-building something that just happens in the background of my life, without constant effort and willpower?”
That’s the question The Wealth Habit was born to answer.
And we wrote it in 2025 (published 19th March 2026) because this is the moment people need it most. More on that later.
How the Two Books Are Built
The architecture is completely different, and that tells you everything about what each book is trying to do.
Financial Joy: A Guided Ten-Week Programme
Financial Joy holds your hand.
It’s split into three parts across ten weeks, designed so you can follow it week by week and emerge with your finances transformed.
The first four weeks lay the foundations – the inner work.
You design your life of financial joy, build a positive relationship with money, tackle your behavioural biases, and write your life vision using our POST Framework (Purpose, Objectives, Strategy, Tactics).
You also take your “Money Selfie” – a net worth snapshot that shows you exactly where you stand. No hiding.
Weeks 5 to 8 get deeply practical.
You master your day-to-day finances and learn our eight strategies for paying off our £380k mortgage in seven years.
Plus, you get a comprehensive introduction to investing in index funds, and explore how to grow your income through career moves and side hustles.
If you’re carrying debt and it’s keeping you up at night, Week 6 alone is worth the price of the book.
Weeks 9 and 10 look ahead.
i.e. retirement planning in serious depth (your financial independence number, the 4% rule, pension types, state pension entitlements).
This is followed by estate planning: wills, trusts, and creating your financial legacy for the next generation.
Each week ends with clear lessons and action steps. You finish with a plan, not just a feeling.
The Wealth Habit: A Four-Pillar System
The Wealth Habit is built as a house.
Four pillars, 20 chapters, and a roof that represents the Wealth Habit itself – a life where money works for you.
- Pillar 1 (Build the Mindset) rewires how you think about money using behavioural science, neuroscience and financial psychology.
- Pillar 2 (Build the Habit) moves you from knowledge to action with specific, named habits you can start today – automation systems, impulse controls, guilt-free spending frameworks.
- Pillar 3 (Build the System) scales everything up through effortless investing, side-hustle strategy, geographic arbitrage and financial check-in rhythms.
- Pillar 4 (Build the Life) ensures your wealth lasts and matters through generosity, relationships and an anti-fragile mindset. That entire fourth pillar has no equivalent in Financial Joy.
Each chapter contains a named Wealth Habit Mantra woven into the text.
i.e. punchy one-liners like “Habits > income” or “Where you live should serve your wealth, not strangle it”, designed to stick with you long after you turn the page.
And every chapter closes with a Pause for Reflection, a Small Action Step and a Chapter Summary.
Where Financial Joy gives you the map, The Wealth Habit gives you the autopilot.
The Feel: Healing vs Building
Pick up Financial Joy, and you’ll feel like you’re sitting down with two friends who’ve been where you are.
The opening chapters are deeply personal.
I (Ken) share the full story of emigrating from Lagos to London at 14 –
e.g. the one-bedroom we shared with strangers, the years struggling to finalise papers, finding free school meal vouchers in the playground and feeling like my prayers had been answered.
The Reebok Classics in Neon Blue bought with my first-ever £80 pay packet from a cleaning job.
The lifestyle inflation years – the Mercedes on finance, the Rolex, the Cartier bracelet, looking successful with nothing in the bank.
Mary shares growing up on a Hackney council estate, watching her eldest brother go from a penthouse to sleeping on the living room floor, starting a paper round at 14, making music CDs to sell in the school playground, and vowing never to rely on a job alone after watching colleagues get cut during the 2008 crash.
Those stories are there because Financial Joy understands that your relationship with money is emotional.
Before you can build, you need to heal.
The Wealth Habit opens differently. It opens with energy.
The introduction tells the story of how we met – and we won’t spoil it here because it’s one of those stories you need to read for yourself.
What we will say is this: it involves a property seminar, a moment of unexpected courage, a commitment wall and a first date that neither of us saw coming.
It’s the kind of opening that makes you smile and then makes you think.
It’s a love story wrapped in a financial vision, and that energy sets the tone for everything that follows.
Now, both books do serious mindset work, but they do different kinds.
Financial Joy’s mindset chapters are about healing: your money wounds, your parents’ money stories, the emotional baggage you’ve been carrying.
The Wealth Habit’s first six chapters (Build the Mindset) are about identity transformation and behavioural reprogramming –
- the Wealth-Identity Shift,
- the Scarcity Loop,
- Money Triggers,
- the neuroscience of why you know what to do but still don’t do it.
Financial Joy asks: where does your pain with money come from? The Wealth Habit asks: who do you need to become to build wealth automatically?
Even the very first page sets the frame.
Before the contents, there’s a definitions page.
Wealth: from the 12th-century “welth” – a state of happiness, wellbeing and joy.
Habit: from the Latin “habere” – to have, to consist of. A small action you repeat until it happens automatically.
Two words. Two definitions. And suddenly you understand the whole book.
Frameworks: What You’ll Actually Walk Away With
Both books are packed with original frameworks, but they’re different in kind.
Financial Joy gives you foundational tools:
- the POST Framework for writing your life vision,
- the Money Selfie for knowing where you stand,
- the Money Journey Map with six stages from insecurity to independence,
- the Joyful Spending Plan for guilt-free spending, and
- detailed retirement calculations, including your financial independence number.
Here’s what that looks like in practice.
In Week 4, you sit down and calculate your net worth for the first time – assets minus liabilities, all on one page.
For many readers, this is the first time they’ve ever seen their full financial picture.
It can be confronting, but it’s also liberating.
One reader told us she cried when she saw the number, but then felt relief.
“At least now I know,” she said. That’s what Financial Joy does. It gives you clarity.
The Wealth Habit introduces a different vocabulary:
- the Habit Loop of Wealth™ (building on work by Tiny Habits, Atomic Habits, but uniquely applied to money),
- the 1% Compound Ladder,
- the Joy-Spend Radar,
- the Set-and-Soar System for automation,
- the Location-Leverage Loop for geographic arbitrage,
- the Financial-Rhythm Method combining Japanese kakeibo and African esusu, and
- four principles running through every chapter: Keep It Simple, Keep It Automatic, Keep It Compounding, Keep It Fun.
Here’s what that looks like in practice.
In Chapter 7, you set up the Set-and-Soar System: your salary lands, and before you even see it, automated transfers have already paid your future self, funded your investments, covered your bills and left you a guilt-free spending amount.
You don’t budget. You don’t decide. The system decides for you.
That’s the shift from Financial Joy’s “I’m in control” to The Wealth Habit’s “the system is in control.”
What’s in The Wealth Habit That You Won’t Find in Financial Joy
If you’ve read Financial Joy and you’re wondering whether The Wealth Habit covers genuinely new ground, the answer is yes. Substantially.
- The identity and neuroscience layer is entirely new.
Six full chapters on mindset rewiring using the latest behavioural science, neuroscience and financial psychology.
The Wealth-Identity Shift, Money Triggers, the Scarcity Loop, the Money-Guilt Cure – these go far deeper than anything in Financial Joy.
If our first book helped you understand why your relationship with money is complicated, this one shows you how to reprogram it at the neurological level.
- The automation architecture is new.
Financial Joy teaches you how to budget, save and invest.
The Wealth Habit teaches you how to make all of that happen automatically, without willpower, through environment design and habit stacking.
- The Global-Wealth Habit is entirely new.
Using geographic arbitrage and location awareness as a wealth strategy, and how this drives retirement outcomes.
We share our own story of leaving London.
In addition, we share the story of a couple from our community who moved from London to Coventry, halved their housing costs overnight and kept their London salaries.
We talk about friends earning UK income while living in Ghana, Thailand and Colombia.
Plus, case studies of people who have fully relocated and resources that helped them to do so.
And for those who can’t or don’t want to move, we show how even shifting a few miles can change everything.
We also have a Plan B Quiz to help you determine if you need a Plan B life or not.
- The Generosity Habit is new.
An entire chapter on giving as a wealth-building habit, opening with the Neapolitan caffè sospeso – the custom of paying for a “suspended coffee” for a stranger.
It draws on the World Giving Index and the neuroscience of why generosity compounds into wealth.
- The Anti-Fragile Money Mindset is new.
We share various case studies, including the story of a British-Ghanaian entrepreneur who watched a banker lose everything in the 2008 crash and went on to build an electric bike company in Ghana from nothing.
Half of all Fortune 500 companies were founded during recessions.
This chapter shows you why and how to think the same way.
Plus, how to thrive in a future of expected wars, pandemics, AI upheavals, recessions, etc, with case studies of people doing so today.
The goal is to help you develop the Anti-Fragile Money Mindset and move beyond the fragility that most people struggle from.
- The AI and future-of-money dimension is new.
We wrote The Wealth Habit with one eye on where money management is heading.
It’s not just about AI side hustles (though the book includes detailed tables of AI-powered income ideas, from custom GPTs to AI digital products).
It’s about preparing you for a future where money is managed digitally, where automation replaces manual budgeting, and where careers are being reshaped by technology.
If Financial Joy gave you the timeless principles, The Wealth Habit equips you to thrive as those principles meet an increasingly digital world.
- The global perspective is much broader.
Financial Joy is primarily UK-focused with universal principles. The Wealth Habit was written for a global audience from day one.
It includes stories from the UK, US, Kenya, India, China, Nigeria, Ghana, Portugal, Japan, Italy, NZ, Australia and beyond.
It references ikigai, ubuntu, la dolce vita, kakeibo, esusu and stokvel.
Financial figures appear in both GBP and USD throughout, so readers everywhere can immediately relate to the numbers.
Perhaps the strongest proof of that global ambition is what’s happened with translations.
The Wealth Habit has already secured two language translations – Complex Chinese and Italian – before it even publishes on 19th March 2026, with more expected.
Financial Joy received its Complex Chinese translation months after publication.
International publishers are picking up The Wealth Habit pre-launch because the message is universal: small habits, repeated consistently, build wealth anywhere in the world.
What’s in Financial Joy That The Wealth Habit Doesn’t Replace
This matters just as much.
The Wealth Habit doesn’t duplicate Financial Joy; it builds on it.
There’s material in our first book that you simply won’t find in the second.
- The deeply personal origin stories
The full, unfiltered account of both our backstories.
The Wealth Habit references our background but doesn’t retell those stories in full.
If you want to understand where we came from and why this mission matters to us so deeply, Financial Joy is where you’ll find that.
- The step-by-step debt elimination chapter
Our eight specific strategies for paying off a £380k mortgage in seven years, plus detailed mortgage advice on no-cap mortgages, consent to let and timing overpayments.
If you’re in debt right now, this chapter alone could change your life.
- The full retirement and pension planning chapter
Step-by-step calculations, the retirement living standards framework, defined benefit vs defined contribution pensions, state pension entitlements, the 3.5% and 4% rule and worked examples for both traditional retirement and early financial independence.
The Wealth Habit doesn’t replicate this. It doesn’t need to.
- The estate planning chapter
Wills, trusts, lasting powers of attorney and intergenerational wealth transfer.
The legal and practical mechanics of protecting what you’ve built live in Financial Joy.
- The day-to-day budgeting masterclass
Granular detail on mastering your daily finances.
The Wealth Habit assumes you’ve got this foundation and focuses on automating what you’ve built.
What Other People Say About Each Book
One of the best ways to understand the difference is to listen to the people who endorsed them. The language tells the story.

What Our Readers Experience
Let us share two moments that show the difference between these books better than any description we could write.
Story 1:
A woman in our community – a working mum, two kids, carrying credit card debt she’d never told her partner about – went through Financial Joy’s Week 4 and calculated her net worth for the first time.
She told us she cried when she saw the number.
But then she felt relief. “At least now I know,” she said.
Within three months, she’d had the money conversation with her husband, cleared two credit cards and started an emergency fund. That’s what Financial Joy does. It meets you in the mess and gives you a way out.
Story 2:
Then there’s a couple in our Financial Joy Academy who’d already done the Financial Joy programme.
They’d built their emergency fund, paid down their car loan and even dipped their toes into investing for the first time.
They were “in control” – but still doing everything manually.
Every month was a decision. Every transfer was a conversation. It felt like effort.
When they applied the Set-and-Soar System from The Wealth Habit, they told us:
“For the first time, we’re not managing our money. It’s managing itself. We check in once a month, and everything’s already done.”
That’s the shift. From effort to autopilot. From “I’m in control” to “the system is in control.”
Mary: Both stories are powerful, but the second one I feel even more personally because I know what it’s like to juggle motherhood, work and finances all at once.
When I was running a nursery, raising two small boys, and building The Humble Penny on the side, the last thing I had energy for was sitting down every week to manually move money around.
The systems in The Wealth Habit exist because I needed them too.
If you’re a parent or a carer or someone who’s just exhausted by life, this book was written with you in mind.
So, Which One Should You Read?
Start with Financial Joy if…
- You’re feeling stuck right now.
- You’re stressed about money, carrying debt, living paycheque to paycheque, or you’ve never properly taken control.

- You need the foundations – budgeting, debt elimination, investing basics, retirement planning, estate planning.
Financial Joy is the book that says: You are not behind. You just need a plan, and we’re going to give you one.
Start with The Wealth Habit if…
- You already feel a bit in control, but want to go further.
- You understand the basics but struggle with consistency or making it automatic.
- You want a system that runs in the background.
- You’re thinking about geographic arbitrage, AI-powered income, or building a financial life that thrives through uncertainty.

👉🏽The Wealth Habit also includes an optional 90-Day Wealth Habit Challenge with a free downloadable workbook, tools designed to take you from reading to doing.
Read both if…
You want the complete journey.
And honestly? Most people do.
Financial Joy gives you the emotional healing, the practical foundations and the technical knowledge. The Wealth Habit turns it all into a self-reinforcing, automated system that compounds for life. Together, they’re the full architecture.
The Mission Behind The Wealth Habit
We need to be straight with you about why we wrote this book.
Because it wasn’t for the royalties (although that would be nice!), and it wasn’t to repeat ourselves.
We’re on a mission to show that wealth isn’t reserved for the privileged few. It’s for people like us.
- People who didn’t inherit money.
- People who didn’t have connections.
- People who started with nothing and built a life from the ground up.
- People who believe in the power of small changes that compound.
If we can do it, so can you.
We wrote The Wealth Habit now because the world needs it now. Not next year. Now.
Look around. People are anxious. The cost of living is squeezing families.
AI is reshaping careers faster than anyone expected.
Wages aren’t keeping up.
The old rules: get a degree, get a job, save into a pension, hope for the best, aren’t enough anymore.
And too many people are watching their financial future slip away while being told that wealth is for someone else.
We refuse to accept that.
One of the core ideas in this book is that wealth is not built mainly by earning more. It’s built by building better habits with the money you already have. Wealth isn’t built in big leaps. It’s built in layers.
- A small automated transfer.
- A guilt-free spending plan.
- A 1% adjustment that compounds quietly over years.
- Those layers, stacked consistently, create something extraordinary.
And the beauty is that anyone can start layering today.
With all the uncertainty around us e.g the cost-of-living crisis, AI disruption, economic change, we felt it was time to write a book that helps people manage money for the future, not the past.
A book that equips you to navigate these seasons with confidence and the genuine ability to thrive, not just survive.
That’s what The Wealth Habit was built to do.
The Honest Truth
We wrote Financial Joy because we wanted to help people who were stuck.
We wrote The Wealth Habit because we wanted to help people who were ready to fly.
Both come from the same place, our lived experience as a couple who went from sleeping on floors and washing dirty pound coins to achieving financial independence at 34 and paying off our mortgage in seven years.
But they serve different moments.
Financial Joy is the deep breath, the reset, the foundation.
The Wealth Habit is the system, the habits, the compounding engine that runs for the rest of your life.
Start with joy. Stay with habit. Finish with freedom.
