I know of almost zero kids that enjoy practicing their instrument as a kid yet I believe the majority of adults are happy for the experience. (I have no data tho). I certainly just wanted to do other things (play with friends) so I showed no or not enough interest for my parents to push/encourge learning an instrument.
Assuming I'm correct following the advice of "see what they're interested in" would seem to lead to worse outcomes at some level.
of course I'm not suggesting shoving things down their throats so to speak rather it seems like there's room for some balance between only encourage their interest and require them to do x?
I want to give my kids the opportunity to pursue wherever their interests take them, but at the same time, I think most kids could use some pushes to be well rounded. I definitely needed that.
