My First Year Investing: Every Mistake I Made (So You Don't Have To)

My first year of investing was like watching someone play a video game for the first time — except the controller was my life savings and there was no reset button.

I did everything wrong. Not some things. Not most things. Everything. And I'm going to tell you about all of it because (a) it's pretty funny in hindsight, and (b) if even one person reads this and avoids my mistakes, my financial suffering will have had purpose.

So grab a snack. This is going to be a ride.

Mistake #1: I Started by Picking Individual Stocks

My first-ever stock purchase was a company I'd never researched, in an industry I didn't understand, based entirely on the fact that my barber mentioned it.

My barber. The guy who once gave me a mullet and called it "European style."

I bought 50 shares of this random tech company because — and I quote my own brain here — "it's only $8 a share, so even if it goes down I won't lose much."

That's not how any of this works. An $8 stock dropping 50% loses you the same percentage as a $800 stock dropping 50%. But my brain saw "low number" and thought "low risk."

The stock dropped to $4 within two months. I learned the hard way that cheap stocks aren't bargains — they're often cheap for a reason.

What I should have done: Started with a broad index fund like VTI or VOO. Own the whole market, not one random company my barber likes.

Mistake #2: I Checked My Portfolio 50 Times a Day

I'm not exaggerating. I actually tracked it once. Fifty. Times.

I'd check it first thing in the morning (before my eyes fully opened). During breakfast. On my commute. In meetings. During lunch. After lunch. Mid-afternoon. Every time I went to the bathroom. Before dinner. After dinner. Before bed. Sometimes in bed at 2 AM because I woke up and my brain went "but what if something happened?"

Nothing ever happened at 2 AM. The stock market is closed at 2 AM. I knew this intellectually. My anxiety did not care about facts.

The problem with checking constantly isn't just the time waste — it's that you feel every tiny movement. Your stock drops 2% on a Tuesday and it ruins your whole day, even though a 2% daily move is completely normal and means absolutely nothing in the long run.

What I should have done: Checked once a month, maybe. Set it and forget it. Your investments are like a garden — they don't grow faster if you stare at them.

Mistake #3: I Panic Sold at the First Dip

Three weeks into my investing career, the market dropped about 4% in one day. Some news about interest rates or trade wars or whatever — I don't even remember because it literally doesn't matter anymore.

But at the time? I thought it was the end of the world. THE MARKET IS CRASHING. SELL EVERYTHING. CONVERT TO GOLD AND CANNED GOODS.

I sold all my positions. Every single one. Then I watched the market recover completely within a week.

I'd locked in my losses and missed the recovery. The classic beginner move. Textbook. If there were a hall of fame for dumb investing decisions, this would be in the lobby.

What I should have done: Nothing. Literally nothing. The math shows that time in the market beats timing the market. A 4% dip is a Tuesday, not an apocalypse.

Mistake #4: I Bought Back in at the Top

After panic selling, I waited for the market to "stabilize" before getting back in. Translation: I waited until everything had recovered and was hitting new highs, then bought back in at a higher price than I originally sold at.

So let me get this straight — I sold low and bought high. The literal opposite of what you're supposed to do.

I basically paid a stupidity tax for the privilege of underperforming someone who just held their position and did nothing.

What I should have done: Never sold in the first place. Or if I absolutely had to sell, used a systematic approach for getting back in rather than waiting for my emotions to tell me it was "safe."

Mistake #5: I Listened to Reddit Like It Was the Oracle of Delphi

Oh, Reddit. Sweet, chaotic, absolutely unhinged Reddit.

I found the investing subreddits and thought I'd struck gold. Thousands of people sharing stock picks and analysis! A community of investors helping each other succeed!

What it actually was: thousands of anonymous strangers with varying levels of knowledge (mostly zero), confirmation bias, and an alarming fondness for rocket ship emojis.

I bought three different stocks because I saw them mentioned in highly-upvoted posts. One of them was a company that, I later learned, had been losing money for seven consecutive years and was under SEC investigation. But the post had awards and 3,000 upvotes, so it must be good, right?

Right?

What I should have done: Treated Reddit as entertainment, not a financial advisor. The person posting "this stock is going to the moon 🚀🚀🚀" might be a 19-year-old who just discovered what stocks are last Tuesday.

Mistake #6: I Chased "Hot" Sectors

Electric vehicles are the future! I should put all my money in EV stocks!

Wait, no — AI is the future! All in on AI stocks!

Actually, hold on — cannabis is being legalized everywhere! Weed stocks to the moon!

I spent my entire first year chasing whatever sector was getting the most hype. By the time I heard about a trend, it was usually already priced in (meaning the stock price already reflected the excitement). I was consistently late to the party, buying at the peak, and watching the price deflate as everyone moved on to the next shiny thing.

What I should have done: Bought a total market index fund and automatically owned a piece of every sector — including the hot ones — without having to guess which would be hot next.

Mistake #7: I Ignored Fees (They Were Eating Me Alive)

"Commission-free trading!" the apps screamed. And technically, they weren't lying — there was no fee per trade.

But I didn't look at the expense ratios on the mutual funds I bought (some were charging 1%+ annually), the premium "research tools" subscription I signed up for ($15/month), or the fact that every time I sold at a gain within a year, I owed short-term capital gains tax at my regular income rate instead of the lower long-term rate.

Over my first year, between high-fee funds, subscriptions, and excess taxes from frequent trading, I probably lost an extra $500-800 that I didn't even register as "losses" because they didn't show up in my P&L statement.

What I should have done: Stuck with low-cost index funds (expense ratios of 0.03-0.10%), skipped the premium subscriptions (everything you need to know is free), and held positions for over a year to qualify for lower long-term capital gains taxes.

Mistake #8: I Tried to "Learn" Options Before Learning Basics

This is like trying to learn backflips before you can walk.

Someone told me I could "make money even when stocks go down" using options. That sounded amazing! I watched a YouTube tutorial, nodded along like I understood, and proceeded to lose $600 on my first options trade.

I still, to this day, could not accurately explain what happened to that $600. It just... evaporated. Into the options void. Where money goes to die.

What I should have done: Mastered the basics first. Buy stocks. Understand how the market works. Learn what P/E ratios and market caps mean. THEN, maybe in year three or four, look into more advanced strategies. You don't need options to build wealth. You need patience.

Mistake #9: I Had No Plan

Ask me what my "investing strategy" was during year one and I'd have said something like "make money in the stock market." That's not a strategy. That's a wish.

I had no target allocation. No idea how much I wanted in stocks vs. bonds. No timeline. No goal beyond "more money please." I was driving without a destination, wondering why I kept ending up lost.

What I should have done: Spent 30 minutes defining a basic plan. Something like: "I'm 28, I want to retire at 60, I'll invest 80% in stock index funds and 20% in bonds, and I'll rebalance once a year." That's it. That's a plan. It doesn't need to be fancy — it needs to exist.

Mistake #10: I Compared Myself to Everyone

Tyler at work made $10K on Tesla. My college roommate was up 200% on crypto. Some stranger on Twitter turned $5,000 into $50,000 on a meme stock.

And there I was, with my boring index fund, up a whopping 8%.

I felt like a failure. Which is insane, because 8% is a perfectly solid return. But when everyone around you is (seemingly) getting rich overnight, steady growth feels like standing still.

What I didn't see: Tyler also lost $15K on another trade he never mentioned. My roommate's crypto portfolio crashed 60% the next month. The Twitter stranger's account was probably fake.

What I should have done: Stayed in my lane. Comparison is the thief of joy, and in investing, it's also the thief of returns — because it tempts you into dumb decisions trying to keep up.

What Year Two Looked Like

After all those mistakes, you'd think I'd quit. I almost did. But instead, I did something radical: I simplified everything.

• Closed my individual stock positions
• Put everything in three index funds (total US market, international, bonds)
• Set up automatic monthly investments
• Deleted the brokerage app from my phone's home screen
• Stopped reading Reddit for stock tips
• Started reading actual books about investing

It was boring. It worked. And it's been working ever since.

Your Cheat Sheet (What I Wish Someone Told Me on Day One)

1. Start with index funds, not individual stocks. Beat 90% of professionals without trying.
2. Automate your investments. Remove yourself from the equation.
3. Don't check daily. Monthly is plenty. Quarterly is fine.
4. Never panic sell. Dips are normal. Crashes recover. Hold on.
5. Ignore the hype. Reddit, Twitter, your barber — none of them are your financial advisor.
6. Keep fees low. They compound against you just like returns compound for you.
7. Have a plan. Any plan. Write it on a napkin. Just have one.
8. Think in decades, not days. You're not a day trader. You're building a future.

Not sure where to start? I wrote a guide that explains investing concepts using coffee shop metaphors, because why not. And if you want to see the actual math behind why investing beats saving, I ran those numbers too.

You're going to make mistakes. Everyone does. But you don't have to make my mistakes. Consider this your cheat code.
