I'm not the least bit surprised. I was involved in the dance business long ago, and the top dancers danced in an effortlessly elegant manner. Beginners danced like drunk cows, and there was every level in between.

Some people learned faster than others.

But nobody was born elegant, and dancing smoothly and elegantly required endless hours of practice, and relentless attention to detail. You'll find even ballroom champions still spending hours going over how to take a step forward, again and again.

BTW, it isn't about making it look easy. It is easy when you've practiced it enough.
