Nothing kills the joy of a hobby faster than trying to make a living out of it.
It’s one of the symptoms of the SYSTEM when a kid shows talent and/or strong interest in a thing, it could be most anything, the adults that this child looks to for guidance push them to make this interest and/or talent into a career. And as soon as that suggestion takes root in that child’s head then it just time before the hobby/talent is abandoned with regret and sadness.
This may not be universal but it’s not rare either - as you know first hand.
Hope one day you can, if you want, get back to what drew you towards playing music in the first place and I hope you find joy in it for nothing more than that.
Is this true? Or is this just “people you know” and what the media you consume tells you?
If it is true then adding in the sources of where you got this information would really help your argument. Hell you may actually get more people to agree with you if you have solid evidence of what you said.
If this is just what “feels” right to you or if this is just something that other people told you is right then maybe look into that and see if reality lines up with what you are feeling and hearing.
