First you go to someone who teaches people to dance - someone who makes their living at doing this - particularly students with two left - ot even two right - feet!
Secondly, you have to WANT to dance. Ask yourself, WHY do I want to dance? To excel and Compete? To improve my health, my physical stamina? To become more popular with the opp S?
Just for the entertainment, the joy of it? So having answered all this - pehaps - find your Teacher and buy your dance shoes.
In the first instance you may well have to buy two LEFT Shoes, But don't give up, it could well work out happily. Listen to your teacher. And practice!
Unless you are congentially incapable of remembering and carrying out instructions, in due course, assuming you really want to, you will dance! You may even enjoy learning!
Perhaps unfortunately, you will then have to buy another pair of dance shoes, this time two RIGHT ones. But as I say, it may well work out happily in the end!
