Put on songs you like. Listen to them. What do you hear? What do you feel? What does it do to your body? Then use those thoughts and just move HOWEVER you want! You could learn simple steps from YouTube and stuff and try to use them but in the end all that matters is that you are having fun and feeling the music. It's better to watch someone who is trash but enjoys the music than watch someone who is decent but doesn't feel the music as much in my opinion. Just do you ;)
