Concentrate on learning the basics. Although this sounds boring, the regular dancers whom you encounter will notice your efforts.
New dancers tend to take big steps. Take small steps!
Avoid rushing. Beginners are usually nervous and rush through moves. Take the all of the allocated beats to finish your move (you have more time than you think!).
If you are a follower, instead of learning a bunch of moves, learn how to follow. Then you can do any move that the leader leads. Also, followers, don’t try to read the leader’s mind and anticipate the move. Just follow what the leader physically leads you to do (along with following the music, of course).
