I think there is not much a dancer needs to know before they start dancing, except just to start.
Still, it's a hard truth of this field that if you fall in love with dance in your early thirties, you have to seriously consider whether you are "too old" already, and to know that you are compounding the already difficult odds for success.
so i'm asking ??? is it worth it?

What career? Perhaps you should call you new chain of studios "Walter Mitty". Someone has already taken the name Arthur Murray.

The deepest definition of youth is life as yet untouched by tragedy.
With age come the inner, the higher life. Who would be forever young, to dwell always in externals?

Before you contradict an old man, my fair friend, you should endeavor to understand him.

"Before you contradict an old man, my fair friend, you should endeavor to understand him. "

Hard when you aren't making any sense.

You have a dream, that's great.

If you want to it be anything more than a dream you are going to have to figure out what you can personally do as a business owner.

Otherwise you will never get beyond the dreaming stage. Sure, you may throw away your present career, but without a plan for what you will do as a studio owner, you will not build anything to replace it.

So what is your plan???

now u are talking !!!!!
that is what i must look !
i must investigate !!!
Therefore search and see if there is not some place where you may invest your humanity
Art is born of the observation and investigation of nature.
Never invest you money in anything that eats or needs repairing.
Practicing the Golden Rule is not a sacrifice; it is an investment.
so what u believe i should do ?

I think it totally depends on what you define as "success."

Is it winning a major champtionship like Blackpool or the Ohio Star Ball? Or at least making it to the top ranks of competitive professional dancing? Then you are starting late. The latest I know of a current champion starting was in his early 20s. To succeed that that level starting at your age, you would need great talent, great dedication, and a lot of time and money to devote to full-time dance training. Even then, the chances are probably not in your favor.

Is it making a living as a dance teacher and having a competitive career? You can certainly do that, but you will probably have to live on a smaller income for the first few years (as you would if, say, you went back to school to learn any other new field).

Is it to become the best dancer you can be? You can start at 90 for that goal. It's never too late to start dancing or to work at being the best you can be.
