They do say, "dance to your own drum" - but that doesn't work very well for couple's salsa :D
It doesn't for sure. I have seen that and I can tell when someone is off-beat with those things. In the same way I don't know how to move to do that, so I refrain from it.
Learning dancing has to be do with a partner, otherwise you never grasp the mechanics fully.
When we narrow the attempts, we fail less, but we also succeed less.
Yes, less risks involves less rewards.
