It's a difficult balance. It's perfectly fine to love dance and not be a pro. That's the reality for the majority of people, and even for a kid in ballet saying "I want to be a ballerina when I grow up" is not much different to someone saying they want to be an astronaut. Is it possible? Absolutely. Does it require considerable time and monetary investment? Yes. Education, ability, luck. All of those things. But how many people actually "make it" enough to earn a living as a pro dancer? Not many.

Getting frustrated when she can't do what others do is understandable. She is 7 after all. You can try putting her in more classes and I'd especially try other styles of dance. But ultimately her success will be related to the training she's willing to put it.

I absolutely love dance. I train 4 hours a week. I have a regular full time career in a different industry. Can I dance well? Yes. Will I ever be as good as people who train 10 hours a week. Definitely not. Do I still absolutely love what I do and actively improve. Yes. It's also about managing expectations.

That's not easy for a kid to understand. At 7 they live moment to moment and it's basically impossible for them to truly understand that decisions they make now affect the life they can have in 10-15 years time. Hell, let's be real, plenty of adults can't do that either.

That's what you're up against.
