I didn't say great or excellent, just good. If you don't like it, you won't get good. Competence is sexy. Shared WTF will get you started, but that's about it. Shared passion is another level entirely.
Agreed - and I'd be the first to admit that I personally took getting competent too far (and that in itself starts getting less social, since it's hours of practice each week with just one partner).
However, the basic initial win for the OP is to get out of the house, and have a blast learning something with a bunch of other people. The aim doesn't have to be to get good - it's a major step just to turn up. I was just trying to suggest that every beginner will be in much the same boat. IMHO, learning to dance is a much easier social activity than 'going to parties', for instance.
