10 Lessons That Took Me a Decade to Learn

Ten years in, the five-year list still holds. Here's what I added since. Most of these I learned the slow way, and the two that stuck hardest came from places I didn't expect: a mat and an automatic transfer.

1. Money is a tool, not a scoreboard

It's only worth what it lets you do and who it lets you help. Chasing the number for its own sake goes nowhere.

A net worth figure doesn't pay for your kid's practice fees or cover you when the car dies. Decide what the money is for first: a cushion for when you get out, a house, time with your family. Then the number has a job. Without one, enough never feels like enough.

2. Value beats cost

The cheapest option often ends up the most expensive once you count what it fails to do.

Boots are the easy example. A cheap pair that falls apart in a few months costs more than a good pair that lasts years, and that's before your feet pay for it. The same goes for a car with no maintenance history, a lowball moving company, or a "free" money seminar that ends in a sales pitch. Ask what it costs over the whole time you'll use it, not just at checkout.

3. Time is the one thing you can't get back

You can rebuild money. You can't rebuild a decade.

That cuts both ways. Years spent putting off a degree because the timing is never right, or chasing something you don't even want, cost more than any bad trade. Treat your hours like your pay: know where they go.

4. Compound interest rewards patience, not timing

The version of you who started five years earlier will almost always beat the one who waited for the right moment.

Here's what that looks like. $200 a month at a 7% average return grows to about $525,000 over 40 years. Start 10 years later and it's about $244,000. Same monthly amount, less than half the result. (7% is an example, not a promise. My math, rounded.) The early years look boring. They do most of the work.

5. Diversify, but don't scatter

A handful of things you understand beats a dozen you're guessing on.

An S&P 500 index fund alone holds about 500 companies. Owning that plus a few things you actually understand is diversified. Owning 15 stocks you picked because they were trending on social media is scattered. If you can't explain why you own something in one sentence, that's your sign.

6. Habits compound the same way money does

Small, boring, repeated decisions are the whole strategy.

Packing lunch, checking your account once a week, paying the card in full. None of it feels like progress on the day you do it. Stack enough of those days and it's the difference between scrambling at the end of the month and having a cushion.

7. Debt can be a tool or a trap

A low-rate mortgage on a home that holds its value is not the same as a maxed-out credit card charging over 20%.

Credit card plans that charge interest averaged 22.15% in the Federal Reserve's latest numbers. Before you take on any debt, ask two questions. Does the thing I'm buying hold its value or earn money? Can I pay it off on a fixed schedule? A VA loan on a home you'll live in can pass both. A car loan on something you can't afford usually fails both.

8. Keep investing in yourself

A skill you use keeps paying you for years. For me, one of the best ones has nothing to do with money on paper: boxing and jiu-jitsu.

I was introduced to grappling in 2012 through Army Combatives, which is built on Brazilian jiu-jitsu, and I trained it again overseas when I deployed to Afghanistan. I've done it on and off ever since. On the surface it's just staying in shape. To me it's a lot more than that.

Boxing pays me back in patience. You have to wait and pick your shots. It also makes you strategic. You come in with a plan, do everything with a purpose, and think about your next move.

Jiu-jitsu teaches you to stay calm under pressure. When someone is about to choke you out, panic is the worst thing you can do. Stay calm, figure out a way out, and you'll be fine. (More on that in What Boxing and Jiu-Jitsu Actually Teach You About Discipline.)

It also gives me confidence, because you're pulling off moves on someone who is trying to do the same thing to you. That confidence carries into everyday life. Those lessons have made me a better person, a better dad and husband, and a better leader in the military.

You don't have to do my sports. Find something that keeps you moving and keeps your mind engaged, and you'll see the compound effect for years. Reading counts too. 8 Books Worth Actually Reading About Money is where I'd start.

9. Consistency beats intensity

A boring plan you stick to beats an aggressive one you quit in month three.

What paid off for me wasn't beating the market. Since 2020 I've just kept putting money into it on a schedule, no matter what the market was doing. That has a name: dollar-cost averaging. FINRA describes it as investing "in equal portions, at regular intervals, regardless of current market conditions."

The intense version is trying to time it: waiting for the dip, going all in when you feel good, pulling out when the news gets scary. The consistent version is the transfer that runs whether you're paying attention or not. You just have to be patient. The results show up later than you want, and then they keep showing up. Jocko Willink calls it discipline equals freedom. My money takeaways from his book are in 9 Key Lessons From Extreme Ownership by Jocko Willink.

One honest caveat. If you're sitting on a big lump sum, FINRA notes that spreading it out often produces lower returns than investing it all at once over long periods. Most of us don't have that problem. Our money shows up a paycheck at a time, so investing it as it lands is dollar-cost averaging by default.

10. This is a long game

Anyone selling you a shortcut is selling you something.

Everything on this list took years to show up: the money, the skills, the way I handle pressure on the mat and at home. If you're getting out soon or just getting started, you don't need to fix all ten this month. Pick one.
