I cannot get my daughter to grasp what you are talking about. She and her mother are on their way north for another 'audition' right now. It is breaking my heart to see this young lady try and try.
If it's college dance programs that she's auditioning for, DON'T PAY! It would be much cheaper, and much more educational, if you provided modest financial assistance for her to pursue ballet instead of college for a while. If I was in your position, I'd try something like agreeing to match every dollar she earns for herself, so she can work part-time at whatever sort of work she can get (maybe teaching children's ballet classes if she's lucky), spend the rest of her time on ballet, and have enough money to survive on her own. I'd suggest that this arrangement NOT involve living at home, first because she needs to get a sense of who and what she really is in the outside world, and second because she needs to start experiencing first-hand what it's like to live on a meager income. This arrangement would have her living on about what a professional dancer with a position in a fairly major company makes, and spending a good deal of time getting much better dance training than she'll get at any college. Put a time limit on this arrangement, maybe two years. You'll be out some money, but not nearly as much as you'd be out after paying for two years of a college degree program in dance, and your daughter will have gotten a heck of a lot more meaningful education.
What part of the country do you live in?
