Finding the right financial literacy book in South Africa can be surprisingly difficult. Much of the financial content available to young people comes from overseas, often using terminology, products and examples that don’t always translate well to South African life.
If Only I Knew This When I Was Your Age was written to offer something different: practical financial lessons for young South Africans, based not on complicated theory, but on lessons learned through nearly twenty-five years of running a business, managing money, making mistakes and learning along the way.
This isn’t a get-rich-quick manual. There are no promises of overnight wealth, hot share tips or predictions about the next cryptocurrency to explode.
It’s simply the book I wish someone had given me when I was younger.
The aim is to help young people understand money earlier, avoid some of the mistakes many of us only recognise later in life, and start building strong financial habits from the beginning.
What Makes This Financial Literacy Book Different
There are thousands of books about money, investing and wealth creation. Many of them are excellent.
The problem is that financial education can sometimes become unnecessarily complicated. For someone receiving their first salary, opening their first credit account or trying to understand how investing works, the amount of information available can be overwhelming.
If Only I Knew This When I Was Your Age takes a simpler approach.
It focuses on practical principles that can be understood and applied in everyday life: managing what you earn, understanding debt, developing good financial habits, appreciating the power of time and compounding, and learning to think differently about wealth.
Lessons From Real Life
The ideas in this book weren’t developed in a classroom.
They came from nearly twenty-five years of running a business, managing cash flow, making financial decisions and, importantly, getting some of those decisions wrong.
I’ve learned that some of the most valuable lessons in life come from mistakes.
The problem is that mistakes involving money can take years to undo.
If someone else’s experience can help a young person avoid even one of those mistakes, then sharing that experience has value.
That’s really where this book started.
Written With South Africans in Mind
A lot of popular financial content originates overseas. The principles may still be useful, but the terminology and examples don’t always feel relevant to a South African reader.
This book was written here, from a South African perspective.
That doesn’t mean the basic principles of managing money are uniquely South African. Budgeting, debt, saving, investing and compounding are universal concepts.
But there’s value in learning about them in language and examples that feel closer to home.
Who Should Read If Only I Knew This When I Was Your Age?
I originally wrote the book with young people between roughly 16 and 30 in mind.
That’s an important period financially.
It’s when many people receive their first proper income, get access to credit, start making larger purchases and begin making decisions that can affect their finances for years.
You don’t need to understand finance before reading the book. In fact, that’s the point.
Young Adults Starting Their Financial Journey
The earlier you understand a few basic financial principles, the more time you have to benefit from them.
You don’t need to earn a fortune.
You don’t need to understand the stock market.
And you certainly don’t need to have your entire life figured out.
You need a foundation.
The book covers practical areas such as budgeting, understanding debt, emergency savings, compound growth, investing and building better financial habits.
The aim isn’t to tell readers exactly what to do with every rand they earn. It’s to help them understand the principles well enough to make better decisions for themselves.
Parents and Mentors
Something unexpected happened as the book developed: I realised it wasn’t only for young people.
It’s also a useful conversation starter for parents, grandparents and mentors.
Talking about money isn’t always easy. Many of us grew up in homes where finances weren’t openly discussed at all.
Giving a young person a book can sometimes open a conversation that might otherwise never happen.
Rather than saying, “This is what you must do,” it creates an opportunity to say, “Read this. Then let’s talk about what you think.”
That conversation may ultimately be more valuable than the book itself.
Learning to Manage Money Before Chasing Wealth
One of the central ideas in the book is simple:
Before worrying about becoming wealthy, learn how to manage money.
Earning more doesn’t automatically solve financial problems. If spending simply increases every time income increases, very little changes.
Learning where your money goes and intentionally deciding what you want it to do gives you far more control.
Building a Budget That Actually Helps
A budget shouldn’t feel like punishment.
It’s simply a plan for your money.
Knowing what comes in, what goes out and what remains gives you information. And information allows you to make better decisions.
That’s why budgeting forms part of the foundation of the book.
You don’t need the world’s most complicated spreadsheet. You simply need to know what’s happening with your own money.
Understanding and Managing Debt
Debt is another subject young people need to understand early.
Used without understanding the true cost, debt can consume income for years. Interest and repayments reduce the money available for everything else you want to achieve.
The book looks at the difference between using debt thoughtfully and allowing consumer debt to control your finances.
The goal isn’t to create fear around credit.
It’s to understand what you’re agreeing to before signing your name.
Lifestyle creep is another part of that conversation. As income increases, it’s very easy for expenses to rise just as quickly.
A better car. A more expensive phone. More subscriptions. More eating out.
Individually, none of those things necessarily creates a problem.
But collectively they can make someone earning considerably more money feel no better off than they did years earlier.
Investing and the Power of Starting Early
One of the biggest advantages a young person has isn’t money.
It’s time.
Understanding compound growth early can completely change how you think about investing.
Small amounts invested consistently over long periods can grow significantly because returns have time to generate further returns.
That’s why the book spends time explaining compounding in simple terms.
The objective isn’t to tell readers which investment to buy. Investment decisions depend on individual circumstances, goals and risk tolerance.
Instead, the book aims to help readers understand why starting early matters and why long-term thinking can be so powerful.
Avoiding the Get-Rich-Quick Mentality
There will always be someone promising a shortcut to wealth.
The opportunity changes, but the sales pitch rarely does.
Young people are particularly exposed to this today because social media can make extraordinary financial success appear normal and easy.
It isn’t.
Building financial security is usually far less exciting.
It involves good habits, patience, consistency and time.
That’s not particularly glamorous—but it works.
Money Is Only Part of the Story
Although If Only I Knew This When I Was Your Age focuses heavily on money, the bigger theme is really about choices.
Financial decisions affect the opportunities available to us later.
Good financial habits can create options.
Poor financial decisions can remove them.
That’s why I believe financial education isn’t simply about becoming wealthy. It’s about giving yourself greater freedom to make choices about your future.
About Andrew Jacobs
Andrew Jacobs has spent nearly twenty-five years running his own business in South Africa.
Over that time, there have been successes, failures, good decisions and expensive lessons.
If Only I Knew This When I Was Your Age grew out of a simple thought: what would I tell my younger self if I could go back and have that conversation?
The answer became a book.
Not because I believe I have all the answers, but because I’ve learned a few lessons that might help someone else avoid learning all of them the hard way.
That philosophy also sits behind the broader If Only I Knew series: practical lessons about money, business and life that are worth sharing.
Knowledge is power, application is key.
