Money Lessons I Learned at 30
(What I Wish I Knew at 20)

If I could sit down with my 20-year-old self, these are the 5 money lessons I'd share – not from regret, but to help you think about money differently and earlier.

Money Lessons I Learned at 30 — What I Wish I Knew at 20

A Letter to My 20-Year-Old Self

If I could sit down with my 20-year-old self and share a few money lessons, these are the things I would tell her. I recently turned 30 – and these are some of the lessons I've learned along the way.

This is not from a place of regret, or feeling that too much time has passed. It's the opposite: if a 20-year-old, or any younger person, comes across this, it can help them think about money differently than I once did.

Lesson 1: Your Income Matters, But Your Habits Matter More

Most people think they have an income problem, when in reality they have a spending problem. I have seen people earning a big salary yet living paycheck to paycheck – and others earning a modest income who are steadily building wealth.

That tells us something important: wealth is not built by what you earn – it is built by what you keep and invest after earning. So I would tell her to make sure that, whatever her income, a fixed percentage always goes to saving and investing first. If you want a closer look at this trap, read why most Kenyans stay broke (and how to escape).


Lesson 2: Budgeting Is Freedom, Not Restriction

For many years I thought budgeting meant saying no to everything. Most of us see a budget as a tool that restricts us. But really, a budget simply tells your money where to go, instead of leaving you wondering where it went.

A simple framework like the 50/30/20 rule is a great place to start:

  • 50% to needs – rent, food, transport, bills.
  • 30% to wants – the things you enjoy, guilt-free.
  • 20% to savings, investments and debt repayment.

I wish I had embraced budgeting from a young age – I wouldn't have struggled to build the habit later in life. For a practical, sustainable approach, see our guide on budgeting made realistic.


Lesson 3: Debt Steals Future Opportunities

Not all debt is bad debt – but unnecessary debt can slow down your wealth-building journey. Money used to repay debt is money that cannot be invested, saved, or used to create wealth.

So before borrowing, ask yourself one simple question: "Will this purchase still be worth paying for 6 months from now?" That gives you a clear sense of whether the debt is truly worth it.


Lesson 4: Investing Is Not Only for the Rich

This is a big myth. Most of us believe investing needs a lot of money and belongs to a rich, elite group. In reality, if you invest slowly and steadily – even with the little you have – you can build wealth.

What matters more is time, not the amount of money. Thanks to the power of compounding, starting early beats starting big. If the belief that you need a lot of money has been stopping you, let this be your reminder: you don't need a lot of money to invest – you need time.

Start where you are, with the little you have, and build it consistently. A money market fund is a great first step, and our article on how consistency builds real wealth shows exactly why this works.


Lesson 5: Emergency Funds Are So Underrated

Life happens. Medical bills appear, jobs change, you can be retrenched, cars break down. Having 3 to 6 months of expenses set aside gives you peace of mind and financial security – and that security is the foundation of financial freedom.

Remember: an emergency fund is not an investment – it is financial protection. The exact figure is relative to your needs, and everyone's number is different, but the goal is the same: a cushion that catches you when life throws the unexpected. A great place to keep it is somewhere safe and accessible, which is why we compare options in MMF vs SACCO vs shares.
