Aye. Passion is what drives us all to exceptional feats really.
You have to enjoy it, want it, revel in it. Any athlete or professional who use their body to the max feels that but dancing has the added buzz of being creative in ways to fire the imagination.
You form dance, you grow dance, you evolve dance. It is a fundamental expression of personality which other physical activities just don't have.
A great insight and thanks for sharing your journey with us.
