The simple answer is no, but you must be willing to put the time and the effort in. For example just say you were going to start learning karate you would be expected to atleast attend 6 hours a week and even then it will take months to pick up the basics. Actually bringing up karate is a good comparison to dancing, there are a few reasons for this and they are when you first start karate you will have to perform stretches and moves that your body has never felt before. This in itself is very similar to learning dance steps and your body and mind will never have felt anything like this.
Ok enough about comparisons, dancing is fun forget about the work involved in learning once you have mastered the art it is very entertaining plus you get to meet a wide variety of people that you can share your success stories, failures and celebrations with.
If you are reading this then you must have some interest in learning to dance so wait no longer, join a group and you could be surprised at what you learn and maybe surprise your friends the next time you go to a party.
