I am not a good dancer but I luuuuuurve grooving to a tune or two, especially when the melody is compelling every cell in my body to move! Who cares if I have two left feet? I am not in a dance competition. I dance because I want to!
Dance when the music moves your body, regardless if that makes you look like a headless chicken flapping around.
Dance when your heart feels the music.
Dance when your soul hears music that your ears have not heard.
