I started investing at 19. And I made every mistake I see young people making today.
I thought I could predict the market. That if I bought enough different stocks, I'd have a "diversified portfolio." That if I followed financial news, I'd know when to buy and when to sell.
Spoiler: It didn't work.
But here's what's interesting. Today, watching dozens of young people wanting to start investing, I see that it's not your fault if you haven't invested yet. There are three barriers literally blocking your way.
The 3 Reasons Young People Don't Invest
1. It seems like a closed world
When I was young, I thought investing was for people in suits with money. That you needed to go to a bank, that there were minimum investments, that only the rich could "play" the stock market.
Wrong.
Today you can open an investment account in 15 minutes from your phone. But nobody explains it that way. You get hit with "technical analysis" and "charting" and "Sharpe ratios" and you think: "This is for smart people."
It's not. Someone just never explained it simply.
2. You think you need a lot of money (you don't)
"I need X amount to start."
False. You need any amount. We're talking $10/month. $50. $200.
But there's this weird mental bias: if you can't invest "a lot," it doesn't seem worth it. So you wait. And wait. And at 30 you still have nothing invested.
Then come the regrets.
3. The fear is real
"What if I lose everything?"
It's a legitimate question. And it stopped me too at first.
But here's the twist: fear of losing money is normal. The problem is that fear paralyzes you. And being paralyzed with $0 invested is 100% worse than investing $100 and watching it drop 20%.
The Mistake Young People Make (That I Made)
When I started investing, I was trying to be a trader without knowing it.
I'd buy a stock, see it go up 5%, think "I'll sell this and move it to another," sell it, pay commissions, start over. Buy 5-6 different companies thinking that was diversification.
Result: I wasted time, paid commissions, stressed myself out, and made LESS than just buying the index.
The mistake is trying to make money fast.
At 20, your superpower isn't your analytical ability. It's time. You have 45 years ahead. That's your weapon.
So what did I do when I figured it out?
I stopped "predicting." I set up an automatic monthly contribution to an index fund (S&P 500, then added MSCI World). And I forgot about it.
Simple.
But there's one rule before you do this.
The Golden Rule: Your 6-Month Emergency Fund
Before investing a single dollar, you need something more important: peace of mind.
I'm talking about an emergency cushion. Money in your bank account (not invested) that covers 6 months of your expenses.
Why 6 months? Because if you lose your job, if your car breaks down, if you have a medical emergency... You won't need to panic-sell your investments. You'll have accessible money.
Some say 3 months. Some say 12. I say 6 is the sweet spot.
Why does it matter? Because the worst enemy of a good investment strategy is having to sell when you DON'T want to sell. And that happens when you don't have a cushion.
With a cushion, you can watch the market drop 20% and instead of thinking "Oh no, I'm ruined!", you think "Hmm, I'll average down this month." (That's called DCA - Dollar Cost Averaging, but that's another article).
First Priority: Focus On Your Career
Here's something important nobody says: if you're 20 and just started working (or still studying), your number one priority is NOT investing.
It's earning a better salary.
Why? Because starting salary is low. Really low. And trying to invest $50/month when you make $1,200/month is almost pointless compared to what you'd gain if you increased your salary by $300.
Investing = {Capital} × {Rate of Return}
If your capital is low (because you're not earning much), compound interest takes decades to work its magic. But if you increase your capital (by earning more), that compound interest becomes exponential.
So before you open an investment account:
- Focus on improving your salary - Learn skills, change companies, negotiate better pay
- Build your career - These first years are when you can grow the most
- THEN start investing - Once your salary is decent
It's not that you shouldn't invest at 20. It's that first earn more money. Then let money work for you.
The Real Fear Isn't Losing Money
Here's what nobody says.
The fear that blocks most young people isn't "What if I lose money?"
It's: "How do I declare this to the tax authority? Do I have to fill out forms? Will I get audited? What if I make a mistake?"
That's the real fear. Because losing money in the stock market is "normal." It's part of the game. But dealing with taxes sounds like "I'm going to jail."
You won't. But you need a good broker to make this easier.
A good broker (Degiro, Interactive Brokers, etc.) gives you automatic reports, explains how to handle taxes, and takes that pressure off.
That's what really stops you. Not the money. Not the market. It's the bureaucracy.
The Strategy That Works (Spoiler: It's Boring)
Forget predicting. Forget trading.
Here's what actually works:
Automatic monthly contribution. Pick an amount ($50, $100, $300, whatever you can). Let it come out automatically every month.
Index funds. S&P 500 (US market) + MSCI World (global market). That's it. If you want extra risk, a small % in emerging markets. But nothing more.
Reinforce on dips. If the market drops 15%, your monthly contribution buys cheaper. That's what you want. Not what you fear.
Forget it for years. Don't check every week. Don't panic sell. Just let compound interest do its thing.
Is it boring? Yes. Does it work? Yes.
Time Is Your Superpower
If you start at 20 with $100/month, by 50 you'll have more money than you ever imagined.
If you wait until 30, you'll still have nothing.
It's not magic. It's math. Your compound interest calculator shows you in 3 seconds. But it's still shocking to see it in numbers.
The Conclusion You Didn't Want To Hear
You don't need to be smart to invest. You don't need a lot of money. You don't need to predict anything.
You need:
- A 6-month emergency fund ✓
- $50-100/month (AFTER improving your salary) ✓
- A good broker ✓
- Patience ✓
That's it.
If you're 20 and haven't invested yet, that's normal. What matters is that first you build a solid career that gives you money to invest. After that, investing does the rest of the work.
