I am not artistic in any way. So I may be biased here.
The problem is expecting to get paid every time someone wants to hear the recording you made 3 months ago (or three years ago, or thirty years ago). I understand it is a means to produce more content, but rarely actually happens.
The waitress at the last restaraunt you ate at has to keep doing the same thing (with minor adjustments) over and over again to keep making a wage. I highly doubt she has delusions of serving one table and making a living for the rest of her "career".
I have a brother who enjoys making music. He subs in his friends bands from time to time because he enjoys playing. During the day he works a normal job, has no ambitions or delusions of "making it" and playing an instrument as a career.
I'll be blunt here: if your music really is as fantastic as you think, you'd already be sleeping on a bed made of money. Maybe you should go and reflect on that.
