I found the article pretty accurate for my own accumulation phase. I remember being on level 1, and envying the carefree grocery carts of my fellow shoppers.
I didn’t necessarily notice the restaurant freedom, but at some point I stopped looking at the price of the meal I want.
I’d say I’m approaching travel freedom. I upgraded my legroom a few inches on a trans-Atlantic flight without blinking at the $100, but I just laughed at the $900 to upgrade to the next step.
But eh, I’m not particularly in a rush towards FIRE. I might be an outlier.
I'm with Sailor Sam. I do no longer blink at restaurant prices, if it is a restaurant I want to go to. However, I get irritated if I have to spend more at a restaurant I'm not into because it was someone else's choice. I also will pick flights in part based by price but also based by preference so not always the cheapest. (I like normal timed layover of 1-2 hours, minimum amount of layovers but I don't mind a 6am flight probably a product of my NY years when those were the flights that didn't get fucked up).
I also didn't blink when I broke my last phone and laptops respectively. I didn't get the top of the line but I didn't worry about price either I got the one that was the best value for me.
I can see some scaling of consumption in some manner as I gain more wealth because I can but it won't be uber extreme.
Very much true for us too.
I planned my last plane trip (to Europe), and while yet, it was Norwegian, we spent extra to actually sit together and have no layovers.
For our upcoming trip to Hawaii, I shopped around and had specific requirements: 1. a kitchen. 2. NO RED EYE I DO NOT SLEEP ON PLANES. 3. A really awesome pool, water slides a bonus. So for sure, I paid attention to the overall cost, but I didn't blink at the $5500 price tag (for 4) compared to what I could have gotten (different island, condo with a normal pool, and a red-eye back) for $3800.
Likewise, when our fridge died, or the computer died, or my phone went kaput...I just replaced them. With reasonably frugal choices ($350 fridge, ?? computer, $250 phone).
