I figured belleofyourball would have an excellent answer to the original post. On a different note, and as odd as it may sound, it is possible, especially for instructors, to never really do much dancing outside of demonstrating during teaching. The same with golf professionals who operate a public or private course. They rarely play the game for fun or competition.
I have always enjoyed social dancing, though it is getting hard to find a place nearby. It's too hard to drive 90 minutes into the city and fight traffic and parking. Getting too old for that.
Basically, I am happy just working on steps and posture; trying to incorporate something new on a fairly regular basis, and then moonlighting as an instructor when the opportunity presents itself.
I consider it an intriguing, challenging and fun hobby for the most part... and I get to the dance studio for brushups, etc. whenever possible. For instance, I will probably be working on smoothing out my Viennese Waltz until my final days! And yet, it is possible I may never do the dance in a social setting. So, go figure.
