Most people think you need a winning lottery ticket or a silicon valley exit to stop working before your hair turns grey. They’re wrong. Honestly, the math is way simpler than that, and it’s mostly about math, not magic. If you’ve spent any time in the FIRE (Financial Independence, Retire Early) community, you’ve likely heard of Kristy Shen and Bryce Leung. Their book, Quit Like a Millionaire, isn't just another dry finance manual; it’s a blueprint for people who weren't born into wealth but want to buy back their time.
The core premise is radical yet boringly predictable: stop spending money on things that don't matter so you can stop working a job you hate.
I’ve seen dozens of "get rich" schemes. This isn't one. It’s about the 4% rule, geographic arbitrage, and a healthy dose of cynicism toward the "follow your passion" industrial complex. Kristy Shen famously grew up on 44 cents a day in rural China before moving to Canada. That kind of background changes how you see a dollar. It’s not a piece of paper; it’s a unit of freedom.

The Math Behind Quit Like a Millionaire
The math works whether you’re earning $50k or $150k, though obviously, one of those gets you to the finish line faster. It basically hinges on your savings rate. Most people save 5% or 10% if they’re "good" with money. To quit like a millionaire in your 30s or 40s, you’re looking at 50% or higher.
Is it hard? Yeah. Is it impossible? No.
Shen and Leung focus heavily on the 4% Rule, which originated from the Trinity Study. The idea is that if you invest your savings in a diversified portfolio of stocks and bonds, you can safely withdraw 4% of the total in your first year of retirement—adjusting for inflation every year after—without ever running out of money.
Why the 4% Rule is Your North Star
To find your "number," you take your annual expenses and multiply them by 25. If you spend $40,000 a year, you need $1 million. If you can live on $30,000, you only need $750,000. This is where people get tripped up. They think they need $5 million because that’s what "rich" looks like on TV. But financial independence isn't about being rich; it's about being free.
The authors highlight how your biggest expenses—housing, transport, and food—are the "Big Three." If you can crush those, the rest of your budget barely matters. You can keep your Netflix subscription if you live in a condo you bought for cash or a city with world-class public transit.
Scarcity vs. Abundance Mindset
Growing up in poverty gives you a "scarcity mindset," which is a double-edged sword. It makes you great at saving but terrified of losing. Shen writes about how she had to train herself to have an "abundance mindset" once she reached her goals. You can’t live in fear forever.
The book argues that you should choose your career based on the Return on Investment (ROI). Don't be a starving artist if you want to retire at 31. Go be an engineer, an accountant, or a coder. Use that high salary to fund your freedom, and then spend the next 50 years doing whatever art you want. It’s a cold take, but it’s practical. Passion doesn't pay the rent, but a solid STEM degree usually does.
Yield over Capital Gains? Not Always.
One of the more technical aspects of the Quit Like a Millionaire philosophy is the focus on taxes and "yield." In Canada and the US, tax codes are written to favor investors over workers. If you earn $50,000 from a job, you pay a chunk in income tax. If you "earn" $50,000 from qualified dividends or long-term capital gains, your tax bill might be close to zero depending on your total income and filing status.
This is the secret sauce.
When you stop trading time for money, you start trading capital for money. It’s more efficient. Shen and Leung talk about the "Cash Shield" and the "Yield Shield." The Yield Shield involves shifting your portfolio toward dividend-paying stocks or REITs when the market is crashing so you don't have to sell your shares at a loss. It’s a psychological safety net.
The World is Cheaper Than You Think
A huge part of the early retirement community's success comes from Geographic Arbitrage. This is a fancy way of saying: earn money in a strong currency (USD, CAD, EUR) and spend it in a place where your money goes further.
Think Portugal, Mexico, or Southeast Asia.
Shen and Leung spent years traveling the world after they quit their jobs, finding that their cost of living actually dropped compared to living in a high-priced city like Toronto. You can get a luxury apartment in Medellin for a fraction of a basement suite in Vancouver. If your portfolio generates $3,000 a month, you're struggling in New York but living like royalty in many parts of the world.
Common Criticisms and Why They (Mostly) Fail
Critics often say, "Well, they were engineers, of course they could save money."
Sure. Having a high income helps. But the logic of Quit Like a Millionaire isn't about the starting salary; it's about the gap between what you earn and what you spend. I’ve seen doctors earning $400k who are broke because they have a $2 million mortgage and two leased Porsches. I've seen teachers retire at 45 because they stayed in a modest home and drove used Toyotas.
The math is indifferent to your job title.
Another critique is the "What about healthcare?" argument, specifically in the US. This is valid. Healthcare is a massive variable. However, Shen and Leung address this by suggesting that once you aren't tied to a desk, you aren't tied to a country. International health insurance or living in countries with socialized medicine becomes an option. It requires flexibility, something most people aren't willing to trade for comfort.
Actionable Steps to Start Your Journey
If you’re serious about this path, you can’t just read about it. You have to move.
Audit Your "Big Three" Immediately
Look at your rent/mortgage, your car payment, and your grocery bill. If these take up more than 50% of your take-home pay, you’re stuck. Can you downsize? Can you sell the car and bike? Can you stop eating out four nights a week? This isn't about "no lattes"; it's about the $500 monthly car payment that is stealing your 40s.
Calculate Your FI Number
Don't guess. Look at your bank statements from the last 12 months. What did you actually spend? Multiply that number by 25. That is your target. Seeing the number makes it real. It stops being a vague dream and becomes a finish line.
Automate the Gap
Set up your brokerage account to pull money from your paycheck the second it hits. If you never see the money, you won't miss it. Invest in low-cost index funds like VTSAX or VTI. Keep it simple. Complexity is the enemy of execution.

Build a Side Hustle (If the Day Job is Slow)
If your income is low, you can only cut so much before life sucks. At that point, you need to increase the "In" part of the equation. Whether it’s freelance writing, consulting, or flipping furniture, every extra dollar should go straight into the investment pot.
Understand the Tax Shelters
Max out your 401k, your IRA, or your TFSA/RRSP. Use the tools the government gives you to keep more of your own money. Every dollar you pay in unnecessary taxes is a dollar that isn't compounding for your future self.
Living like a millionaire doesn't mean having a golden toilet. It means having the power to say "no" to a boss, a toxic environment, or a life you didn't choose. It’s about being the architect of your own time. The math works, but only if you have the discipline to follow it through the boring middle years.
Start by tracking every penny for 30 days. You’ll be surprised where the leaks are. Fix the leaks, fill the bucket, and eventually, you can stop carrying the water.
