I didn’t become a millionaire because of some brilliant investment or because I suddenly started earning six figures.
Looking back, it was the tiny habits I repeated over and over, year after year, that built my wealth. And honestly? Most of them were pretty boring.
In this post, I’m breaking down the 12 tiny money habits that helped me become a millionaire by 40 — so you can see exactly what actually moved the needle (hint: it’s not what you think).
Stick around for #12, because it’s the one people skip over the most, and it might be the most important one on this list.
12 Small Habits That Helped Me Become a Millionaire By Age 40
1. I Invested My Money Before I Had a Chance to Spend It
I set up an automatic transfer from my paycheck straight into my investment account — directly into the investment I wanted to make.
I didn’t have to think about investing, and I didn’t have to take time out of my day to actually do it. It was all automated.
That makes a huge difference. When you take yourself out of the equation and just let it run in the background, you’re not relying on willpower every single month.
I never became wealthy because I had huge amounts of money sitting around, or because I had a rich uncle who left me his life savings.
It was just small amounts, every single month, over a long period of time.
I invested in my 401(k) and got my company match.
I set up a brokerage account and automated it too.
I still do automatic investing today — I just let it grow and compound over time.
2. I Tracked My Money Instead of Avoiding It
I liked seeing how much money was coming in, and I liked knowing where it was going.
This can be done pretty simply.
I like using a free app called Empower — you can hook all of your financial accounts and log in quickly to see where your money’s going, make sure your bills are paid, and even watch your net worth grow over time.
In the very beginning, before apps like that existed for me, I had a spreadsheet — actually, before that, I had pink graph paper where I wrote down every transaction by hand.
Luckily, we don’t have to do that anymore, but if it works for you, by all means, write it out.
Knowing where all my money was going helped me build wealth, because I wasn’t afraid to look at my money. If I saw I was spending a lot in one area, I could make adjustments.
Most people think of budgeting as, “This is what I can spend, and I can’t go over” — it feels restricting.
I like to call it a spending plan instead. It’s not about restriction. It’s about knowing where you’re spending so you can adjust — more into investing, more into a travel fund, wherever it needs to go.
What gets tracked gets measured, and what gets measured gets improved.
3. I Lived Below My Means, Even When I Could Afford More
I wanted extra to invest, so I lived below my means on purpose.
When I first started saving, I built up an emergency fund so that if something bad happened, I’d have the money to cover it — and I kept that fund in a high-yield savings account.
That one small move alone will help you build wealth faster.
I hardly ever went out to eat when I had my 9-to-5.
I brought my lunch to work 99% of the time.
I’d rather save that money for a trip or invest it.
I didn’t want a higher car payment, higher rent, or a bigger mortgage.
I kept my expenses low, which meant I had more money to spend on the things I actually wanted — without being frivolous about it.
4. I Spent Money on Assets Instead of Just Things
I saved and saved.
I eventually was able to save up for a down payment on a house.
I decided to get roommates so I could collect some extra income and provide a nice place for some single women to live in.
It wasn’t until about 10 years later that I wanted to invest in another property.
I was able to save up for a down payment for that investment property.
Once I had a renter in my investment property, I was collecting more income every single month.
Rentals aren’t completely passive, but they’re semi-passive, and that one move built my wealth astronomically.
I’ve had rental properties and roommates, and I’ve also spent money on things that improved my own skill set and knowledge — instead of just buying more clothes or shoes (and truth be told I did some of that too, but didn’t go into debt for those things).
I read Rich Dad Poor Dad years ago, and it had a huge impact on me.
The idea is: you invest in assets, and then the income from those assets pays for your liabilities — the things that cost you money.
Want to upgrade your car? Great — first buy a rental property, start collecting that income, and then let the asset pay for the car payment.
We don’t want to do it the other way around: buy the fancy car first and think about the rental property later. Flip the order so your assets pay for your liabilities.
5. I Made It a Habit to Learn About Money Every Single Week
I have a friend who’s a really good mentor — very successful in real estate and the stock market.
I asked him a ton of questions about both, and by learning from him, I was able to take those principles and apply them in my own life.
That’s how I ended up purchasing multiple rental properties and my own home.
I didn’t grow up in a household where investing was taught.
My parents are great at saving and taught me to be frugal (I still remember being told to turn off the lights when I left a room), but investing itself I had to go learn.
And I still do — I continue learning about money and about optimizing my life, so I can actually afford to live the life I want.
6. I Avoided Lifestyle Inflation
This one’s about not comparing yourself to the Joneses — your neighbors, your friends — and matching every upgrade they make: the car, the clothes, the handbags.
When you get a raise, it’s tempting to spend that new money on little upgrades instead of saving or investing it.
Avoiding lifestyle inflation was one of the small habits that helped me become a millionaire at 40.
If I’d spent every bonus or increase in income on things that didn’t really mean anything to me instead of investing a portion of it, I wouldn’t be where I am today.
And I’m not saying you need to invest everything. There’s still a balance spending intentionally and enjoying life.
7. I Made Big Decisions Based on Long-Term Goals, Not Short-Term
The way I do real estate investing isn’t a short-term play.
I invest for the long term.
I invest in buy and hold rental properties.
I’m not creating hundreds of thousands of dollars in a year, but I am creating that over the years.
I invest in the stock market as well.
There were times I wanted a quick win. I’d buy into a company and sell shortly after an increase.
Over time I realized that wasn’t the best strategy for me, so I shifted to a longer-term focus, and that’s what’s actually built my wealth over the years.
8. I Invested in My Own Skill Set
The more I can grow my own skill set, the more valuable I become — and the more people are willing to pay for those skills.
That doesn’t happen overnight. It’s a long-term game.
I got a marketing degree. I waited about 10 years and got my MBA.
Since then, I’ve invested in different coaching programs, courses and more. Always learning.
Skills complement each other, and the more you learn and implement what you’re learning, the more you’re able to make — which means the more you’re able to invest and then increase your net worth over time.
9. I Built Multiple Income Streams
This didn’t happen overnight either — I started small.
First it was my 401(k) through my 9-to-5.
Then I started investing in the stock market through my own brokerage account and a Roth IRA.
Then real estate.
I started my own business and invested in that.
Now I also have affiliate income and became an Amazon influencer.
There are a lot of different ways I make money today.
But when you’re just starting out, focus on one income stream first and get that going — even if it’s just your 9-to-5.
Grow your skill set, become more valuable at your job, ask for raises, and if you’re not getting what you want, look elsewhere.
Your current job can be a huge income stream on its own.
A lot of people jump straight to “I need a side hustle” without ever really growing their main income stream first.
Start there, then expand.
10. I Took Care of My Health
This one’s a little different, but it made a big difference too.
Taking care of our health.
I’m talking about taking control of what we can control.
I like going for walks. I love Zumba (attending and leading Zumba toning). I love hiking. I love drinking water.
This might not sound related to money, but it is.
When we take small steps to improve our health, we get a clearer mind — and a clearer mind is what lets us focus on growing our wealth.
If we’re stressed about our health, not moving our bodies, not getting outside, we’re not going to feel like we’re in a place to actually improve our money situation.
11. I Created Before I Consumed
There’s so much content out there — so many influencers, so much to scroll through on social media.
It’s easy to get sucked in and spend hours just consuming. I try to focus on creating content first (I’m not perfect at it, but I try).
Creating is what actually grows a business and increases income. If you’re spending all your time consuming and never putting anything out there, you can’t grow.
Ask yourself, “What do I want to create?” instead of “What do I want to buy?”
There was a point where I got pretty comfortable with where my income was — comfortable, but not fulfilled.
So I kept learning even after I felt comfortable, and that’s what led me to start thrivingwithtiff.com and get back into my YouTube channel.
I’m still learning. Right now it’s learning AI and how to use it to run my business more efficiently.
Making and creating things is what helps me feel fulfilled, whether that’s a course, financial coaching, books, or YouTube videos.
12. I Stayed Consistent Over the Long Term
This is the one people skip over the most — and it’s huge.
People get a few months in, see their net worth dip because the market tanked, and think, “This isn’t working” or “It’s not worth improving my skills.”
But if you stay consistent — keep investing, keep building your emergency fund, keep buying real estate, keep learning new skills, one after another — you build wealth over time.
I didn’t start with a net worth of just under a million. I started with $0.
After my first paycheck I might’ve had $100 to my name — I don’t remember the exact number, but it was small.
If I’d thought, “There’s no way I’ll ever get to a million, why bother,” I never would have gotten there.
We don’t get there if we never try and never stay consistent. Consistency is the key to growing your net worth to a million dollars and beyond.
FAQ
Do I need a high income to become a millionaire by 40? No — none of these habits require a huge salary. The core of this list is automating small, consistent investments over a long period of time and letting compound growth do the heavy lifting, rather than waiting for a big windfall or a high-paying job.
Is real estate required to build wealth? No. Real estate was one piece of the puzzle, but the habits that matter most — automating investments, tracking your money, avoiding lifestyle inflation, and staying consistent — work whether you’re investing in a 401(k), a brokerage account, real estate, or all three.
How long does it actually take to see results from these habits? Years, honestly — and that’s the point. These are small, repeatable habits compounding over a long period of time, not a quick-win strategy. Consistency through the slow years is what makes the difference later.
