To help yourself be a good dancer I feel you should: 1.Take some group lessons then practice,practice,practice. 2.If your a lady dancer "DON'T BACK LEAD". You must learn to "Follow your dance partner (I think this is the most important but also most difficult thing for lady dancers to learn). It's the males responsibility to lead you around the floor (let him do that). Having good technique is very important because without good technique all a dancer is doing is moving their feet and the rest of your body may not look very graceful.
I'm sure there are lots of other things to help you enjoy dancing.. Having the correct instructor,dance partner and a positive attitude are right up there on the list. Good luck,get dancing and Have Fun!
