A good dancer is an educated one, so dont abandon school.
Dancing is a tough career, but I'm glad I spent it at the Royal Ballet.
I do take class because I still dance, and yes, I do slip into class with the Royal Ballet from time to time.
I enjoy the freedom of modern dance as well as the constraints of classical dance.
So if the dance is five minutes long, make yourself run for perhaps eight minutes. That way, you over-train and the dance will seem easier.
It's another myth that dancing distorts or destroys your feet. If you have the right shaped foot to start and a good, strong technique, your feet should be fine.
