To date I've grossed about $6 from music, but I've spent thousands, upon thousands on music!!
LOL!
I wouldn't trade it for the world. I love being a musician. I love the experience I've had.
I'm no longer, "in the music business," in any sort of old style music business you can possibly think of. Being a musician has taught me marketing, and being a music producer has kept me in tune with technology (extremely important in this day and age.)
I do not look to the audio/visual arts as a way of supporting myself directly, but I certainly look at them as a way to add to my overall life experience, and support me in my other endeavors.
Hope this helps,
Cheers
Jonathan
