Insructor. How right you are when you wrote."We fill them with useless knowlenge and over teach to sound smart"
Thats why I always say that a Technique Class Only is the best way to go where correct technique is the main issue and not filling the students with variations which none can do correctly and is forgotten the next morning.
Chines Proverb.
Tell me and I will surely forget.
Show me and I may remember
But make me do it and I will certainly understand.

Not where I dance! The joy is there as is as much perfectionism as the individual wants.

Most I know are dancing for pleasure and exercise and our instructor is great about meeting that need while teaching the steps well.

Well, I'll be honest when I compete I want to win that trophy. I want to feel that all my hard work has paid off. But, you must dance for yourself, and the passion that you feel inside. Yet there are two different reasons for dancing: competition and perfomance, and secondly: social dancing. People all want to have fun when they are social dancing, to meet new people, to enjoy the evening, to make your heart sing through dance movement. There is nothing quite as exciting as the musicality of dancing.

I so agree with the instructor. I have been studying for 3 and 1/2 years and can not put together a routine, because I've been taught bits and pieces.

To move to the music and exercise!!

I guess this is my category;
I simply want the excercise and I enjoymusic

IT GIVES INDIVIDUALS A CHANCE TO SELF EXPRESS.

Besides the ones you mentioned,
1) Out of the house and away from the TV.
2) To please my girlfriend.
3) To chalange myself.
4) To watch others dance and to learn new moves from them.
5) To keep my dance skills fresh.

Anything that keeps you moving is a good thing.
Dancing is a great choice because of the music and the challenge of strength and balance that it calls for.
I have been a sports writer most of my life, so I know and admire just about every sport. It has helped me grasp a full appreciation for dancing, which I have done since I was a young boy.
I tell friends that there are more things to learn and try in just one dance, such as the Fox Trot, than there are in some entire sports. So imagine trying to learn and remember steps and variations for several different dances.
I find it fascinating and energizing.

Flamboyance!! People dance because they want to show off their skills. Something like: "Hey Ma, I can dance."
