Over the past year, I set out on a mission: to uncover the habits and decisions of people who managed to retire before age 40. I interviewed 50 people who had escaped the 9-to-5, built wealth, and stepped away from full-time work long before the typical retirement age. These weren’t trust fund babies or crypto lottery winners.
These ordinary people made intentional choices with their money and time. And while their paths varied—some started businesses, others invested wisely, a few lived extremely frugally—they all made one surprising financial decision that set them apart: They stopped chasing status and started optimizing for freedom. Almost every early retiree I spoke with said the same thing: at some point in their 20s or early 30s, they realized that owning nice things didn’t make them feel rich—owning their time did.
One woman who left her marketing job at 33 said, “I used to think I wanted a luxury apartment and designer clothes. Then I realized I wanted to wake up without an alarm clock and spend the day with my kids.”
They flipped the script. Instead of measuring wealth by material possessions, they measured it by how little they needed to live the life they wanted.
This subtle shift had a massive impact on their finances. When most people get a raise, they spend more on a bigger house, a nicer car, and more dinners out. However, these early retirees maintained their lifestyle even when their income grew.
One software engineer told me, “After my first big raise, I didn’t upgrade anything. I still lived with roommates and drove a beat-up Civic. That extra money went straight into investments.
Within five years, I was done.”
They weren’t being cheap—they were being strategic. Every dollar they didn’t spend became a seed for future freedom. Many early retirees built businesses—consulting, freelance writing, niche websites, online courses, digital products, and local services.
But they all had one thing in common: they were scalable without demanding all their time. A 35-year-old who retired from his online bookkeeping business said, “I didn’t need to become a millionaire overnight. I just needed a business that made $5K—$10K a month, didn’t need me 24/7, and let me invest the profits.” They optimized for consistent cash flow and low maintenance.
Once they saved enough and had a portfolio of investments, they let their business fade or kept it as a side hustle. Almost everyone I interviewed saved at least 50% of their income, with some pushing that to 70% or more. For people in high-earning fields—or entrepreneurs with strong cash flow—it’s more about choices than income.
One 38-year-old ex-ad executive said, “When I was 30, I made $180K a year. I lived like I made $50K, saved, and invested the rest. People thought I was weird.
But now I wake up in Spain daily and do whatever I want.”
The key wasn’t just earning more, but not upgrading their life to match their income.
