So I live in a (relatively) big city now. I'm always fascinated by the (social) super structure that is a city, and also by public transport inside cities. I like how life here never stops. You can find things to do at all hours of the day. I like all the weird and strange things the city has to offer.
It also has it's downsides. It gets busy, polluted, dirty and noisy. There's an airbnb close to my appartment and the guests party til 6 in the morning sometimes, on weekdays. If you complain, people say 'you live in a big city, what do you expect?' like it's the normal thing to do. I miss nature sometimes.
I think I'll eventually move to a village. Preferably at sea. But to be young in a city is a blessing at the moment.
I lived most of my younger years in arguably one of the biggest cities in the world, I don't regret it. Very recently moved from Tokyo to a much smaller town. Not quite countryside, but it is in the mountains and significantly smaller than Tokyo (<100,000 population in the whole area compared to millions).
There are things I miss about Tokyo; I love cooking and the ready availability of international markets and ingredients was definitely nice to have. Public transportation was WAY better in Tokyo, and might be the biggest thing I miss. It doesn't take me long to get back into the city if I really want to, but honestly I have only done that a couple times so far.
However, it is much cooler, cleaner air, and generally a less fast-paced lifestyle that I can appreciate. Nevermind the cost of living differences and the amount of space I have. My flat is almost 3x the size of what I had in Tokyo at the same price, and my area is actually fairly "expensive" for an area outside Tokyo.
If my work allowed for it, I wouldn't mind going more rural. Having land and being able to grow some of my own veg would be wonderful. I would prefer to stick to the mountains, I don't do hot weather well. It would have to be a job I could do remotely though, because my field wouldn't really have many opportunities in the countryside.
