I used to think wealth was something that happened to other people.

The ones who got lucky with timing, or had rich parents, or stumbled into the right opportunity at the right moment.

Then I watched some of my peers from their early twenties start making choices that seemed small at the time. Nothing dramatic. Just consistent decisions that compounded over the years.

Fast forward a decade, and the gap between those who did certain things in their thirties and those who didn’t became impossible to ignore.

Your thirties are a weird decade. You’re finally earning decent money, but you’re also facing bigger decisions about life, relationships, and what you actually want. The choices you make during these years will determine whether you retire comfortably or keep working because you have to.

So what separates people who retire wealthy from those who stay broke? Here are eight things the wealthy did differently.

1) They treated their health like an investment, not an expense

Most people in their thirties think they’re invincible. They skip workouts, survive on terrible sleep, and treat their bodies like they have unlimited warranties.

I learned this the hard way when I was building my second startup. I stopped exercising, gained weight, slept four hours a night, and convinced myself I was being productive.

Turns out, I was just destroying the one asset that everything else depends on.

Here’s what nobody tells you about wealth: you can’t enjoy it if you’re sick, exhausted, or dealing with preventable health problems in your sixties. The people who retire wealthy understood that gym memberships, quality food, and preventive healthcare weren’t expenses. They were investments in being able to actually use their money later.

Start treating your body like it’s the vehicle carrying you to retirement, because it is.

2) They automated their savings before lifestyle inflation kicked in

When your income jumps in your thirties, something dangerous happens. You start thinking you deserve nicer things.

Better apartment. Nicer car. More expensive dinners. And suddenly, making twice as much doesn’t mean saving twice as much. It means spending twice as much.

Wealthy retirees figured out a simple trick: they automated their savings the moment they got a raise, before their lifestyle could expand to fill the space.

James Clear talks about how systems beat goals, and this is the perfect example. You don’t need willpower to save if the money never hits your checking account in the first place.

The broke people waited to “see what was left” at the end of the month. Spoiler: there’s never anything left.

Set up automatic transfers to retirement accounts, investment accounts, whatever. Make it happen before you can spend it. Your future self will thank you for not upgrading to that luxury apartment.

3) They learned the difference between assets and liabilities

In my early twenties, I thought buying stuff was how you showed you’d made it. Nice watch, expensive clothes, the newest tech.

Then I started my first company and realized that wealthy people think about money completely differently.

They ask: does this make me money or cost me money?

That car you’re financing? Liability. It loses value the second you drive it off the lot. The rental property you’re considering? Potentially an asset if it generates income.

This sounds obvious, but look at how most people in their thirties spend money. They’re accumulating liabilities while thinking they’re building wealth.

The people who retire wealthy spent their thirties acquiring things that generated cash flow or appreciated in value. Real estate. Index funds. Businesses. Skills that increased their earning power.

Everything else was just consumption, and they kept it minimal.

4) They kept their circle small but their network valuable

There’s this myth that successful people are constantly networking, collecting business cards, and connecting with everyone.

I’ve found the opposite to be true.

The people who built real wealth had small circles of close relationships and a broader network of genuine connections. They didn’t waste time on surface-level networking events or maintaining relationships that went nowhere.

What they did do was stay in touch with people who challenged them, taught them things, and opened doors when it mattered.

I keep in touch with former co-founders and early employees, and those relationships have been more valuable than any transaction. But I also let go of friendships that were based on who wanted something from me.

Your thirties are when you figure out who actually matters. The wealthy made those distinctions early and invested deeply in relationships that were mutually beneficial.

Quality beats quantity, every single time.

5) They increased their income, not just their savings rate

Here’s an uncomfortable truth: you can’t frugal your way to wealth on a mediocre income.

Sure, cutting lattes and canceling subscriptions helps. But there’s a ceiling to how much you can save.

There’s no ceiling to how much you can earn.

The people who retired wealthy spent their thirties aggressively increasing their income. They switched jobs for significant raises. They developed skills that made them more valuable. They started side businesses. They negotiated hard.

I see too many people optimizing the wrong thing. They’ll spend hours finding the best savings account that offers 0.5% more interest, but they won’t ask for a raise or look for better opportunities.

Focus on the big levers. A twenty thousand dollar raise beats a thousand dollars in annual savings by a ridiculous margin.

Get better at what you do. Make yourself more valuable. Then make sure you’re being compensated for that value.

6) They learned that discipline beats motivation every time

Motivation is what gets you started. Discipline is what keeps you going when motivation disappears.

The broke people in their thirties made financial decisions based on how they felt. Motivated to save this month? Great. Not feeling it next month? Spending spree.

Wealthy retirees built systems that worked regardless of motivation.

Tim Ferriss talks a lot about creating environments that make good decisions automatic. That’s what the wealthy did with their finances.

They had rules. Non-negotiable percentages going to savings and investments. Spending limits that didn’t change based on mood. Automatic systems that ran whether they felt like it or not.

I learned this running my first company. The days I felt motivated were easy. The days I didn’t were when discipline mattered. Same applies to building wealth.

Create systems, follow them religiously, and let discipline carry you when motivation fails.

7) They separated their identity from their income

This one almost destroyed me after my failed startup.

I had tied my entire sense of self-worth to what I was building and how much I was making. When it all fell apart, I had nothing left.

The people who retire wealthy figured out early that their identity couldn’t be wrapped up in their job title or bank account. They built lives outside of work. They cultivated relationships, hobbies, and interests that had nothing to do with money.

This actually made them better at building wealth because they didn’t make desperate decisions based on ego or fear.

They could walk away from bad opportunities. They could take calculated risks without their identity crumbling if things went wrong. They made clearer decisions because money wasn’t everything.

Your job is what you do. It’s not who you are. Figure that out in your thirties, and you’ll make better choices with money.

8) They stayed patient when everyone else was chasing quick wins

Finally, here’s the thing that separated wealthy retirees from everyone else.

They understood that building real wealth is boring.

No get-rich-quick schemes. No day trading. No crypto gambling (at least not with serious money). Just consistent investing in index funds, real estate, and their own earning power over decades.

Greg McKeown’s work on essentialism really drives this home. The wealthy focused on the few things that actually mattered and ignored everything else.

They watched friends chase trends and lose money. They saw peers make risky bets that occasionally paid off but usually didn’t. And they just kept doing the boring, proven things that worked.

Compound interest is boring. Maxing out your retirement accounts is boring. But boring works when you give it thirty years.

The people who retire wealthy learned patience in their thirties while everyone else was still looking for shortcuts.

Final thoughts

Look, I’m not going to pretend that everyone has equal opportunities or that these eight things guarantee wealth.

Life is complicated. Some people face obstacles that make building wealth exponentially harder. But if you have the capacity to make these choices, your thirties are when they matter most.

The gap between those who retire wealthy and those who stay broke often comes down to consistent decisions made during this one decade.

You’re not too late if you’re reading this in your thirties. You’re right on time.

Start now, stay consistent, and remember that the boring path usually wins.
