Welcome to df Achilles! Moves to practice in front of a mirror? What sort of dance music they play at the social dances you want to go to. I guess that waltz, foxtrot, west coast, hustle would be the ones? Put on the music for these dances and see if you can move to the beat, making one step for each beat, or one step for every two beats, and recognize where each musical phrase begins. Being able to identify when to start and hitting the beats are two critical elments of dancing. You can then check out clips on the web etc and try to imitate what you see by carrying out the moves in front of the mirror.
