Most of us left school knowing how to solve quadratic equations. Almost none of us left knowing how to read a bank statement.

That gap is exactly why so many smart, hardworking people with decent jobs still feel broke, confused, or one bad month away from disaster.

So here are 10 money concepts that that kids should learn early.

1. Cash flow — money in vs money out, tracked over time

This is the difference between feeling rich on payday and being broke by the 20th. Most people don't have an income problem, they have a cash flow problem, money leaves and they genuinely couldn't tell you where it went.

A positive cash flow occurs when your income exceeds your expenses and negative cash flow occurs when your expenses exceed your income.

2. Net worth — what you own minus what you owe

Your salary is not your net worth . Your net worth is an accumulation of all your assets minus you debts. A man on ₦150,000/month with no debt and ₦500,000 saved is wealthier than a man on ₦800,000/month who owes ₦2 million across three banks and a cooperative.

3. Inflation — the increase in cost of goods and services over time

Nigeria current inflation rate sits at 15.93%; which means what 10k could get you in January, would not suffice in June . Prices don't need your permission to rise, and "I'm saving it" means nothing if what you're saving is shrinking in value every year it sits there.

4. Opportunity cost — what you give up when you choose one thing over another

Every naira you spend is a naira that can no longer do something else. This isn't about guilt tripping parents, it's about being honest that there's always a trade-off, even when nobody points it out to your child.

5. Emergency fund — 3-6 months of expenses saved for the unexpected

Some people call it their safety net. This is the difference between a crisis and an inconvenience. Job loss, medical bill, family emergency, without this fund, one bad month turns into two years of debt repayment.

Pick one of these you're weakest at right now and fix it this month. Not next year. This month.
