Let's talk about this ... seriously!
There are so many people who are "know it all" and we all know few of them. right?
The last you want to claim is the know it all type who claims to be artistic! You can't know everything when it comes to art, you just can't. Not only that, there is no such thing as a know it all artist. If someone claims to be one, run the other direction ...
So when it comes to belly dancing, if your teacher claims to be the best and acts like a know it all, what would you do?
