Isn't it an option to settle somewhere and do gigs in the area mostly?
If you want to starve....
Maybe going about it this way would be helpful to you? But then of course you'd have to be interested in having a home-life as opposed to living out of a suitcase.
My situation and your friend have similarity, but there are a few large differences which I don't need to go into.
I have a place in Asheville where I call "home" and typically visit at least a few days every month. Some months I can come home a lot mid-week, if it's within a 10 hour drive of the weekend gig. I have recently been offered a job in Asheville singing in a soul band with full-time musicians...but it's a huge cut in pay to play in a cover band so I asked to only do Wednesdays until we can increase the income on weekends locally.
So yea, I'd love it if playing locally paid off....but it doesn't.
But more to the point of the OP, there has to be some very talented woman out there who wants to live on room service while seeing the world for the rest of her life.
At least that's my theory. lol
