For some people, it is also a challenge just to LET GO in public enough to allow the expression that goes along with the dance. The result is very beneficial as well. Of course dancing can bring you enjoyment for your entire life, and everyone loves dancers.

As such there are no acredited teachers. So, look for experience in your teachers, and be sure they have the ability to convey to you the important aspects of the dance , so you can learn faster and in more detail, instead of spinning your wheels forever in class.

So beware of teachers demanding your absolute loyalty because, besides reeking of self-interest, it limits what you can get from dancing, which is inspiration from a variety of sources, a sense of community, and socializing with everyone on the scene. The kind of competition that turns students against one another is very destructive to the dance community.
