Sounds a lot like writing too...this is from a perspective of living here - there is no income guarantee - that is if you earn a lot one month - the next it might be peanuts - it is a very competitive too and also there is a very real problem of burnout
The only positive is you can be your own boss if you have your own biz -
Personally I am happy with it being just a passion and hobby
I love listening to music and I have followed the journey of many singers - it is a tough one as well
