In my 20s and early 30s I was pretty restrictive with spending. This was motivated by goals of financial flexibility (not strictly FIRE, maybe more FU money so I would never feel trapped by a terrible job). For about 3 years midcareer I took a 75% pay cut to work at a nonprofit passion project. I was spending ~20% more than I earned for this period, funded via savings, and being mindful of every dollar.
With the privilege of being able to choose, I’ve personally found it easier to be frugal on fewer, bigger decisions (housing, car) and more lax on everyday expenses (groceries, coffee, etc.). For many years, Spouse was great at making simple things feel fancy: candlelit rice-and-beans dinners, picnic dates, homemade cards and baked goods for celebrations. There are some tendencies towards minimal consumption that I have for reasons beyond money, like enjoying camping and road trips over resorts, so I also find those “easier” to spend less on.
We reached FI a couple of years ago, got busier (career, toddler, extended family obligations, volunteering), and developed some minor health problems. For the past couple of years I’ve prioritized time and health. Sometimes that means opting out of buying something entirely so I don’t have to comparison shop, clean, and store an object. Other times that means buying 3 pairs of supportive shoes at full price and returning the 2 that don’t work.
For now, our MO is picking certain categories of minimal spend. We spend the bare minimum on kid toys, travel, entertainment, and household goods for now. We are spending freely for health (PT, immunity supplements, pregnancy support), quality childcare, and time (cleaners etc.). There’s also a house renovation going on that we saved for in cash over the past 6 years, so we’re also indulging on parts of that where it makes sense.
Even with plenty, I wouldn’t say I’m fully relaxed about money. I worry sometimes about losing touch with frugality muscles. I worry even more about making sure my kid has a healthy mindset and skills for managing money and isn’t a spoiled rich asshole. I’m still running expenses through YNAB, checking in on spend-to-savings ratios monthly, and overall portfolio 2-3 times a year. I tend to see managing money like a garden: if I tend to it a bit at a time it’s pretty doable, but if I let things go haywire for a couple seasons or years it’s a lot harder to regain control.
