Some people don't believe in going to dance schools. Maybe they're right. It would be far more useful to travel and live and train by learning the moves directly from the people who dance them in their own communities around the world. Why suffer in dance schools when you can travel the world?
Even if dance schools are the answer to all of the world's dance problems, does that obligate you to attend? Can't the world of dance schools survive without one more dancer? You could be that trailblazer that shows all of the rest that there are many paths.
For you die hard fans of dance schools who have been dreaming about it since childhood, they do offer a lot in the way of in-depth instruction, support, and the opportunity to specialize in a particular school of dance. Dance schools are not the be-all end-all in a successful dance career, but they are a healthy part of the process.
