These 13 Books Will Make You Rich and Change the Way You Invest

I’ve read over 120 books on money and investing—but these 13 underrated ones completely transformed how I see the world. I’m confident they’ll do the same for you.

1. The Millionaire Next Door – Understanding the Wealth Triangle

You’ve probably heard of this one, but it still flipped my understanding of wealth. The authors introduce something called the wealth triangle. It’s simple: take your age, multiply it by your pre-tax income, then divide by 10. That number? That’s your expected net worth.

So let’s say you’re 35 and make $150K a year. 35 × 150,000 = 5,250,000 ÷ 10 = $525K. That means your net worth should be $525,000.

When I found out where I stood, I realized I was falling behind—and it lit a fire under me. This triangle became a personal scoreboard.

2. The Psychology of Money – It’s Not What You Know, It’s How You Act

This book taught me that building wealth isn’t just about knowledge—it’s about behavior. The author dives deep into behavioral finance and how most of us make money decisions emotionally, not logically.

I’ll never forget a friend of mine, Tom. Super smart guy—read charts all day, lived and breathed finance. But when the market dipped, he panicked and sold everything. Meanwhile, my cousin, who barely knows what a stock is, just kept her auto-investments running. Fast forward—she ended up way ahead. Why? Because she stuck to the plan.

Consistency beats genius.

3. Think and Grow Rich – Find Your Definite Chief Aim

This classic isn’t just about grinding harder. It’s about having one specific goal that drives everything. The author calls it your definite chief aim.

When I started my YouTube channel, mine was simple: “Do YouTube full-time.” I wrote it on a sticky note and looked at it every morning. Visualized the freedom, the flexibility. People laughed when I said it out loud. But now? I’m laughing.

Once you have your aim, focus on two things:

4. The Entrepreneur Revolution – Build Systems, Not Stress

Hustling harder isn’t the answer. This book flipped my mindset: stop doing everything yourself. Start building systems—automated routines that work for you.

Spending hours sorting emails? Automate it. Create filters. Forward repetitive stuff. Free up your brain to work on high-impact projects. The more systems you build, the less heavy lifting you’ll do—and the more you’ll get done.

5. Unscripted – Escape the 9-to-5 Trap

This one hit home. The author dismantles the idea that the 9-to-5 is the only path. A salary? It’s the slowest way to get rich. Promotions depend on things you can’t control—office politics, company goals, layoffs.

Want financial freedom? Look beyond your paycheck. Start a side hustle. Invest. Build your own escape route.

6. So Good They Can’t Ignore You – Master Your Craft

Stop chasing vague “passions.” Start mastering rare and valuable skills. The author calls this the craftsman mindset—like a woodworker perfecting their art.

When I got bored of spreadsheets at work, I taught myself Python. Automated my reports. Suddenly, I was the only person in the office who could do that. That made me valuable—and gave me leverage to ask for more.

Master something few people can do, and you control your career.

7. The Unfair Advantage – Use What You've Got

This book shows you how to spot your unique edge using the MILES framework: Money, Intelligence, Location, Education, Status

Even if you didn’t go to a top school or know the right people, you have advantages. Maybe it's money saved up, hands-on experience, or living in a city with job opportunities. Stop focusing on what you lack—use what you have.

Growing up, I used coupons and wore the same shoes until they had holes. That frugal mindset helped me save and invest enough to quit my job while others were still stuck in the grind.

8. The Third Door – Create Your Own Path

Picture a nightclub. There’s the front door where everyone lines up, the back door for VIPs—and then there’s the third door: your own way in.

I once crashed a coffee shop to “accidentally” bump into a top entrepreneur because the line to talk to him was too long. That’s the third door—being creative, being bold. It’s how people succeed when traditional paths are closed.

9. Essentialism – Focus Only on What Matters

The 90% Rule changed everything for me: if an opportunity doesn’t score at least 90% on your personal success scale, it’s a no.

If your job drains you and your boss is toxic, stop wasting energy trying to win a losing game. Use your evenings to upskill, job hunt, or build your side hustle. Every hour you invest in a high-ROI future matters.

10. Hell Yeah or No – Cut the Noise

Simple rule: if it’s not a “hell yeah,” it’s a “no.”

This helped me stop people-pleasing. I used to overspend on social events just to avoid FOMO. Now, if something doesn’t truly excite me, I pass. My energy, health, and bank account all improved. And guess what? My real friendships got stronger too.

11. Someday Is Today – Kill Procrastination with the 5-Second Rule

Anytime you feel like you should act—count down from 5 and do it. That’s the 5C rule.

Cold winter morning? Alarm rings at 6:30 AM. I don’t want to get up. But I count down: 5-4-3-2-1—and I jump out of bed. No thinking. Just doing. That momentum pushes me straight into the gym or deep into work. Action beats hesitation.

12. Start With Why – Know Your Reason

You want to be rich? Cool. But why?

The author’s Golden Circle says true success starts with your 'why'—not your 'how' or 'what.' When I was burning out working my job and building my business at night, I kept going because I remembered my parents struggling with money. That image fueled me.

When your “why” is clear, your actions feel purposeful—not like a chore.

13. The Winner Effect – Stack Small Wins

Winning is addictive. Small victories actually rewire your brain, giving you confidence to take on bigger challenges.

When I started posting blogs, getting 100 views felt huge. That pushed me to reach 1,000. Then 10,000. Don’t aim for the grand slam right away—just stack wins.

Final Thought

Even if you’re doing everything right, it can feel like you’re not getting ahead. That’s because you might be falling into one (or more) of the 5.5 biggest wealth killers.
