Some anecdotes from that time:
I had a $30/mo phone plan that got me 100 minutes, and 5GB of data at HSPA+ speeds. I basically never worked from home, even if that had been an option, because one too many `npm install`s or video conferences would've set me over the edge. I brought my personal laptop to the office to install OS updates, and took downloads back home on a flash drive. And if I had an unexpected call to a 1-800 support hotline - one that I knew would take an hour - I'd literally go find a payphone, where you could call it for free (although it's a much higher charge to the recipient).
I developed a strong love of free-to-me media and entertainment. I was a voracious reader of library books, got my news off broadcast TV, listened to FM radio for music (to be fair, I'd always - and still - done that), and so on. I was attending one or two tech meetups a week.
I didn't have a car. Being a 15-minute walk from a train station helped drastically, but I wasn't as close to the city as most of my colleagues were (maybe 20min over others' average). Visiting my parents took 115 minutes (30 minutes by car) and I did it every other week. Twice a week, I'd take a commuter rail train south of the city, then walk 20 minutes to get where I was going. Most of the time I'd bum a ride back to the station with someone else there. All said, it was probably two extra hours of commuting whenever I did this. There were even times where I'd carry odd things home from Home Depot on the train.
And then, as we got older, many of my friends started to move far out of the city, to places unserved by our transit system. I was totally dependent on my friends still in the city to carpool, even though I was almost certainly making more than they were. I wish - truly I wish - that I could say that this was the straw that broke the camel's back, what made me snap out of it.
Sadly, that honor went mostly to both my work changing (much more teleconferencing / Zoom), and my family situation changing (needing to commute out to the burbs regularly, sometimes with little notice).
I still remember some of the jibes I'd get while doing this - "why do you make life so hard on yourself?" and "you don't know how to have money".
I look back on that time and do think it was an interesting experiment, and to an extent, I'm glad I did it for the perspective. But really, I was naive. I wasn't doing something that somehow made me more independent, or less wasteful. I was dependent on much of other's output, and really only wasting my own ability to be productive.
