If you want to build wealth and live comfortably in retirement, investing isn’t optional it’s, essential. Yet for most people who don’t work in finance, investing feels confusing and intimidating. I get it. In the early days, whenever people talked about the stock market, my eyes would glaze over.
But after years of self-teaching, reading books, making mistakes, and slowly becoming more confident, I learned something important: investing isn’t as scary as it seems when you follow a few simple principles.
Experts like Warren Buffett have their “golden rules,” but I’ve added my own spin based on my experiences. Hopefully, these lessons help you on your own investing journey.
Why I Chose to Self-Manage My Investments
I’ve always been the type who likes to understand how things work. That’s how I approached personal finance, not overnight, but through weekly reading, studying investing books, and learning from my mistakes.
There’s nothing wrong with hiring a professional (as long as you ask the right questions first), but self-managing taught me discipline. The mistakes I made early on ended up saving me thousands later because they forced me to build rules that protect my emotions, decisions, and long-term goals.
Below are the investing rules that made the biggest difference for me and can help you grow wealth consistently without feeling overwhelmed.
1. Keep Cash You Don’t Invest
The worst thing you can do is invest every dollar you have and then get blindsided by a job loss, medical bill, or emergency.
If you’re forced to pull money out early, you lose compound growth and you may owe taxes and penalties.
Build an emergency fund of 3–6 months of expenses in a high-yield savings account (or a short-term CD).
When I started, I split my savings between a Roth IRA and an emergency fund until I hit six months of expenses. Then I shifted more into investments.
Cash first. Investing second.
2. Keep Learning (Forever)
Even after years of investing, I still re-read books and find things I missed before. Successful investing isn’t about memorizing everything, it’s about consistently exposing yourself to new ideas. The more perspectives you hear, the more confident and informed your decisions become.
3. Don’t Invest in Anything You Don’t Understand
One of my early mistakes was buying things I barely understood, mostly because someone recommended them. And yes… I lost money. Before investing in index funds, ETFs, bonds, or individual stocks, understand:
If you can’t explain how it works, you shouldn’t invest in it.
4. Remove Emotion From Your Decisions
Investing becomes dangerous when emotions take over. Maybe your family has ties to a company, so you buy the stock without checking its financial health. Or the news screams “market crash,” so you panic-sell. Fear and excitement are terrible financial advisors.
Train yourself to:
-
Stop tinkering with your portfolio
-
Avoid checking accounts every day
-
Ignore fear-based media headlines
Invest with logic, not emotion.
5. Start Early and Invest What You Can
One of the most important investing lessons: time is your best friend.
Compound interest (interest earned on top of interest) accelerates your money’s growth the longer you stay invested.
Starting at 25 vs. 35 can mean hundreds of thousands of dollars over a lifetime.
Even if you can only invest small amounts, start now.
You’ll never regret being early, only being late.
6. Don’t Try to Time the Market
Every expert on TV claims to know when the market will rise or crash, but nobody can consistently predict it. Guessing the “perfect” time to buy or sell usually leads to missing big gains. Instead, lean on dollar-cost averaging; investing a set amount at regular intervals. It removes emotion, flattens volatility, and keeps you steadily building wealth. Stay in the market. Stay consistent.
7. Keep Your Portfolio Simple and Diversified
The best portfolios are boring, not complicated. Simplicity has outperformed complexity for over 40 years. You don’t need 20 funds or exotic strategies to grow wealth. Diversification matters, too. Don’t put everything in stocks. Mixing in bonds or other asset classes protects you during market downturns.
Simple + diversified = steady long-term growth.
8. Don’t Chase Hype or “Hot” Stocks
Beginners often get caught up in stock hype, the media buzzes, influencers shout about “the next big thing,” and friends brag about returns. That excitement can tempt you to invest without research.
If everyone is talking about a stock, that’s usually your sign to be cautious. Remember the Bitcoin frenzy? People bought at peak prices because of hype and watched their investments crash shortly after.
Stick to your plan. Hype is not a strategy.
9. Avoid Raiding Your Investments Early
Withdrawing from investments too soon destroys long-term growth and can trigger penalties and taxes (especially with retirement accounts). This is why your emergency fund is crucial. It protects your investments so they can grow uninterrupted.
My process looked like this:
-
Calculate overall savings rate
-
Split it between emergency fund + retirement
-
After hitting 6 months of savings, I maxed my Roth IRA
-
Extra savings now go toward my brokerage account and long-term goals
Let your investments stay invested.
Final Thoughts
You don’t have to be a financial expert to invest confidently. Start with the basics: protect your cash, learn continuously, keep emotions in check, stay consistent, and stick to simple, diversified strategies.
These rules helped me build long-term wealth, and they can help you do the same.
