What roll does classical ballet play in the lives of those who practises it?

I've been doing classical ballet since I was three, I dance six hours a week and always wanted to be a classical ballet dancer. It is very important to me, I couldn't live without it, it's very beautiful and has become my way of expression.
Although it can be gruelling and sometimes repetitive it is inspirational to watch such great dancers as Darcey Bussell on stage. I love ballet and hope it continuous to be practiced forever.
