The other thing your are not that well adapted for is parenthood (lots of getting shit together and going someplace on a schedule) and that is harder to take a break from
But most of the import places you have to visit stops during weekends.
Edit: For example, when I was a kid I spent most of my time at home playing with toys during weekends. I don't see why that would be a bad life for a kid. When they get older to 8-10 they can get around on their own so no need to baby sit them any longer, at least if you live in an European city.
Most people on Earth don't live in European cities. I grew up in the suburbs I couldn't go anywhere myself. Public transportation just isn't a thing around me. Not to mention all the stuff that has to be done around the house.
As for parenthood its not just about bringing your kids places. They want to play, they need to eat, they need diaper changes. Kids are a ton of work I love every minute of it, but man is it difficult.
Yeah, I think it's tough for a lot of people without kids to understand what weekends are like for the first few years. If you don't completely hate your job you'll probably at least somewhat look forward to Mondays, when you can get back to work for a rest. Doesn't last forever though; I'd say I'm past that phase now with the kids 8 and 6.
Anecdote from Asian lifestyle: Weekends are usually busier than weekdays with kids. Weekdays are school and study. Weekends are extracurricular sports, tutors, music, etc.
“Playtime” is a tool used to prepare the child for the next lesson.
