The number of steps you know is not important.
Execution is everything.
Good ballroom dancers create the illusion of effortless dancing. Most new dancers don't realize that it is an illusion and that their first efforts at ballroom dance look horrible and feel horrible to their more experienced partners. As a beginner you don't know how perfectly right it feels for two people to dance as one until it happens to you for the first time. Dancing is much more about moving in perfect harmony with your partner than it is about moving through a specific patterns of steps. I also much rather hear a lady compliment me on being smooth than her being dazzled by my step vocabulary.
