You've seen the numbers: the 25x rule, the 4% withdrawal rate, the studies on whether the money will last. Here is what no spreadsheet can show you: what it actually feels like to walk away from your career, and whether it's worth it.

In 2016, at forty-three, my husband Trin and I left our corporate jobs, sold nearly everything we owned, and spent almost a decade moving slowly through the continents, one at a time. We had no guarantee the money would be enough, and we weren't even sure what this lifestyle would cost.

Will the money be enough?

You can't know for certain. Calculate it all and give yourself the best chance, but life doesn't follow the spreadsheet, even without changes as drastic as ours. At some point you have to take the leap and make corrections along the way.

What we learned is that slow travel costs far less than we imagined. We averaged less than $19,000 a year for the two of us. When you have time, you wait for the lower fare, pick the next destination based on the best deal, and shop on Tuesday when everything is half price. We still said yes to the big dreams, like the Galápagos and Antarctica.

FIRE number chart at the 4% rule (25 times a year's spending): slow travel for two at $19,000 a year needs $475,000; the Lean FIRE ceiling of $40,000 a year needs $1,000,000; the average US household, $81,905 a year in the BLS Consumer Expenditures 2025 survey, needs $2,047,625.
Bonnie and Trin's $19,000 a year is a $475,000 FIRE number at the 4% rule, under a quarter of what the average US household's spending needs ($2,047,625, from BLS's $81,905 for 2025). The average household is all consumer units, not only couples. Free to use under CC BY 4.0: credit firenum.com with a link.

Our net worth kept rising, too, even though we'd left well-paying jobs behind. Rental real estate and index funds did the quiet work, and compounding is a wonder. If you're a spreadsheet junkie like me, you can see our cost of travel by country.

Can you retire on 500k? Bar chart of $475,000 spending $19,000 a year (4%), raised with inflation, 100% S&P 500, every January start since 1872. After inflation, the median start year had $678k after 10 years, $952k after 20 and $1.5M after 30; 1 in 10 start years ended below $254k, $271k and $386k. The balance was above the start in 105 of 145, 102 of 135 and 107 of 125 start years, and none ran out within 30 years.
Could $475,000 alone have paid for it? On 154 years of US stock returns, in the median start year it was worth $952,000 after inflation 20 years later, and no start year ran out within 30 years. Bonnie and Trin funded travel from rental income; this is the 4%-from-a-portfolio version of their number. Free to use under CC BY 4.0: credit firenum.com with a link.

And if you try it and end up back at work? You still tried. You won't spend years at your desk wondering "what if?"

What will you do with all that time?

The usual advice is to start hobbies before you retire. We couldn't. Corporate life left no room for anything on the side, and I suspect that's true for many people. Often the new passion shows up only after, because that's when there's finally time to explore it.

For us, travel filled the hours: researching where to go and where to stay, then actually doing it, on trails and on long walking tours of cities. Trin did most of the planning, so I still needed something productive of my own. For me that became writing, but I had to learn it. I promised myself one post a week, and that steady practice became a skill, and then a passion. This month I'm publishing my second book.

There was no room for that in my old calendar. On the road we had real time to sit inside a new culture and to have a conversation that ran past midnight with no alarm waiting on the other side.

Who are you without the title?

In the U.S., identity is welded to work. At a party, the question isn't who you are; it's what you do. I had an easy answer: director at a Fortune 50 company. Once the title was gone, I had to figure out how to answer that question.

Trin, easygoing by nature, barely felt the shift. I'm a driven, type-A person, and I needed a purpose for every hour. Work is a good thing; we're made to work and create. The question was whether I could feel productive another way. That's not a failure of FIRE. It's the bill for letting a job do the answering for too long.

The upside is that we finally had the time to build a better answer.

The bottom line

Was it worth it? Yes. Not because every day was easy, and not because the future ever stopped being uncertain, but because the life on the other side turned out to be bigger than the one we left. I wouldn't have learned to write inside my old job. Trin wouldn't have had a decade of roads to figure out. The money, watched instead of worshipped, did what money is for: it paid for the experience.

The reality of FIRE isn't the withdrawal rate. It's waking without an alarm clock and the freedom to decide what the day is for.
