You do not have to achieve the dexterity and fluidity of professional dancers to be confident dancing. As long as you can walk then you can dance too. That is why there are dance schools. Before you rule the classes out, you should know why dancing is so important. Dance lessons allow you to overcome your inhibitions which can actually be standing in the way of getting ahead in your life. Everyone has one of those days when nothing seems to fall into placing and talking about it does not seem to make it better and this is the best time to put your dancing shoes on and get on the floor. You may have to dance in front of people you have just met and this is a great way of getting away from stage fright.
Dance lessons will give you something to look forward to no matter how crappy your day is. Even though you will be in the learning phase, it will be fun and turning down an evening of fun is not sensible. You can make new friends there and at least you will have something in common compared to trying to make acquaintance with total strangers you know nothing about and the great news is that you will be able to develop the friendship beyond the classes. You cannot have a lot of friends because each one of them will affect your life in a different way. You need all the self-esteem you need to go through your life which means you have to take risks like performing in front of an audience.
Dancing is a form of exercising too and if you do not want to spend a lot of time in the gym, you can have fun while achieving physical fitness in dance classes. The classes do not just start with a bang and you will be able to undergo strengthening exercises which make sure your muscles are flexible enough as well as prevent you from being injured that easily. When you are dancing freestyle, you can bring in whatever moves you wish for and you can even develop your own routine and practice it or teach it to other people which is a great way for you to put your creativity and imagination into action.
