This Seemingly Harmless Habit Is Costing You a Fortune
There’s a $28 habit that’s quietly keeping millions of people poor.
Not just broke — stuck.
And chances are, you’re doing it without thinking.
Maybe it’s:
•
A daily $7 coffee and $21 lunch
•
A couple of Uber rides
•
A streaming subscription here, a gym you don’t use there
It feels small. It feels normal. But according to Kevin O’Leary?
“That’s not lunch. That’s your million-dollar retirement going out the window.”
It’s Not About Income — It’s About Discipline
Most people think they’d be rich if they just earned more.
But Kevin calls that a lie:
“People aren’t poor because they don’t make enough.
They’re poor because they waste what they have.”
Here’s the math:
•
$28/day = over $10,000/year
•
Invested at 8% annually over 40 years = $1.5 million+
•
Lost, one overpriced salad at a time
So what’s the solution?
Just one word: Discipline.
The Secret Portfolio His Mother Built
Forget Wall Street. The smartest investor Kevin ever knew was… his mom.
Here was her system:
•
Put 20% of every paycheck into dividend-paying stocks and government bonds•
Never spend the principal — only reinvest the returns•
Diversify:◦
No more than 5% in any one stock
◦
No more than 20% in any one sector
She followed this strategy for 50+ years.
When she passed away, Kevin discovered she had quietly built a massive fortune — better than most hedge funds.
“That’s how I invest now. Exactly like Georgette.”
The Real Reason Marriages Fall Apart
Here’s the most shocking moment in the interview:
“Most marriages survive infidelity.
They don’t survive financial stress.” – Kevin O’Leary
Kevin interviewed top divorce lawyers across the U.S.
They all said the same thing: Money, not cheating, destroys relationships.
Why?
•
Couples don’t talk about money early
•
One partner overspends
•
The other tries to keep up
•
They fall into debt and resentment
•
Boom: Divorce — and the loss of up to ⅔ of total wealth“Your first child in marriage isn’t a baby.
It’s money. And it sits at the dinner table with you every day.”
Want to Be Rich? Learn This One Concept
From Steve Jobs, Kevin learned a mental model that changed everything:
Signal vs. Noise
•
Signal = the top 3–5 things you must do today
•
Noise = everything else — distractions, scrolling, self-doubt
Jobs was 80% signal, 20% noise.
Elon Musk? “Probably 100% signal.”
Kevin applies it like this:
•
Is that $28 lunch signal? Noise.
Noise.•
Setting up your investment plan? Signal.
Signal.•
Answering every email? Noise.
Noise.•
Blocking 1 hour to learn financial basics? Signal.
Signal.“The ones who fail? They’re 50/50.
The ones who win? They guard their focus like treasure.”
The Boring Blueprint That Builds Wealth
Kevin’s personal investing rules:
•
Allocate 15–20% of every paycheck•
Use ETFs that track the S&P 500•
Add bonds for safety (especially as you age)•
Never own more than 5% of one stock or 20% of one sector•
Never outspend yourself in any 30- or 60-day cycle•
Get rid of your mortgage by your 40sIt's not exciting. It’s not trendy.
But it works.
The $28 Habit That’s Killing Your Freedom
This isn’t about skipping coffee.
It’s about choosing freedom over impulse.
Because every time you keep that $28 in your pocket —
and invest it with discipline —
you’re buying your way out of being poor.
One boring day at a time.
“Wealth doesn’t come from big bets. It comes from small choices repeated consistently — for decades.” – Kevin O’Leary
