I know a guy who turns up at milongas every week with a new, whiz-bang move that usually draws looks of great admiration. I know how he does it, he watches videos and each week practices a new move on the crowd. It's a great learning philosophy. The best bit is that he'll always show someone how to do the moves, if they ask. There are plenty of people who won't though, shrugging of requests with "I don't know. I just do it" or not even being polite about it. Are you happy to share new/signature moves with other dances or do you prefer to keep them to yourself?
