how do you become a famous dancer
asking that is just like asking how to be a famous singer, or a famous actor. Sadly in this country, a lot of people don't recognize talent anymore. I suggest you maybe get a job doing some sort of dancing thing, maybe start doing musicals which involve dancing or something... But dancing isn't as "famous" as maybe singing, in fact, I don't even no any famous dancers. Keep Moving Forward and Never give up.
I mostly agree with selderz but maybe you should audition for a dance show or something.
