I have brought up this topic as this is a common question that keeps a lot of beginners (and some intermediate) from progressing from classroom dancers to dance floor dances.
Would not knowing a lot of moves make you a boring parnter? Come contribute how / what you think can be done to help improve your position as a dancer.
Vivir con miedo es como vivir a medias
A life lived in fear is a life half-lived.
