- I can walk to the grocery store and back in < 15 minutes
- I no longer have to drive to concerts and events
- There's plenty of affordable food options nearby and even more restaurants to sit down at
- I can go sightseeing for $5 by hopping on the nearest bus or train
- A lot of like minded people that are interested in their local community, a big shift from the peak suburbanism I grew up around
- I can fill my social meter in the morning by walking around people watching
- Multiple bike routes and off road paths within a mile or two
A lot of this depends on functioning transit, but in general as a slightly introverted person I wound up enjoying the city way more than I anticipated. There's negatives of course but most of that boils down to cars (and thankfully most of my neighborhood seems to be pushing back on american car dependence) and density (which brings plenty of benefits as well). I think the only thing I find myself really missing here is easier access to green/outdoor spaces, and while there's been some progress it feels like there's not enough of a push there. Thankfully the bike culture here is growing what seems to be very quickly and vocally, I find riding a bike on low stress routes gives me what I was looking for out of walking around in a forest preserve in the suburbs
If you live in a city with good transit you can save a lot without owning a car, few and far between in the US though. Thankfully it's getting better, especially in regards to personal transit like bikes!
