Imagine you are in a music high school in Romania, having 42 hours of school a week, while you have to practice your instrument normally at least two hours a day (you just can't get by in my high school without that). Now imagine that it takes you around 45 minutes to get to school and another 45 minutes to get back... That's more than 64 hours spent each week with school, going and coming back from school, or with school related things.
This is of course without counting homework, only home instrument practice. So excluding practicing at weekends (which leads us to over 60 hours a week instead of over 64) and dividing by 5 (the number of working days in a week), it means on average you need about 12 hours a day with "school, going and coming back from school, or with school related things". Which is more than the huge majority of the jobs, as far as I know.
Just because where you live "insane kids" have very little school, it doesn't mean it's the same everywhere.
