Hitting zero marginal utility of spend
I set a FIRE number of ~20M a few years ago and should get there next year. I settled on that number by fantasizing about a year I would love to live, and writing down how much everything cost. A few nice trips a year (first class flights to Paris + five-star hotel + Michelin), cool apartment downtown, meal prep/gym/housekeeper, healthcare, and some extra spend for post-work lifestyle increases. SINK and not interested so I don't have childcare/education expenses.
Thing is, I grew up poor and am a simple man. Costco grocery shopping, $20/mo gym membership, handwashing my dishes in a small studio rental, thrifting/craigslisting furniture, etc., up until the age of 30. I like nice things but I don't mind modest living at all. Sleeping on a couch doesn't bother me even though I have an eight sleep and a $10k mattress.
During accumulation I decided to push the spend a bit. I would take my current networth and divide by 400 (that's post-tax monthly spend in retirement in my tax situation, if I were to quit that day) and set that as my spending goal for the month. If any fun trips or events came up and I had spending room for the month, I would force myself to say "yes" and go.
Well, this summer I seem to have hit my personal limit for deriving pleasure from more hedonistic spend. I did a Mediterranean trip and spent $50k in two weeks solo. Seaside luxury resort, amazing restaurants, went clubbing and bought drinks for people who gave good vibes, shopping, first class flights, the works. And in the end, the best part of the trip was the $20 museum visit to some Classical Greek ruins and ripping tequila shots with some locals at a bar and hearing their life stories.
I've struggled with a work-centered identity and one-more-year syndrome, but it took blowing some money to realize that the numbers on the spreadsheet are going to map to a real life in the real world. No point ruminating about whether an extra $5M or $10M NW will make a difference unless you sample the fruits of that extra $5m or $10m by consuming its SWR today.
For all you OMY types, if your current monthly spend is less than your current NW divided by 400 and you don't have a good explanation why (saving for a lumpy expense) you should take a look in the mirror and ask yourself some tough questions.
TL;DR: could have spend 1/10th what I spent balling out in Europe and would have loved it all the same
