I come from a very vaudevillian family.
Steps come up all the time, but not dances.
Creating a dance is like coming up with a Chuck Berry riff.
Start dancing immediately. Run to the closest dance studio, and study the style of dance of the music you love. If you love hip-hop music, go to a hip-hop class. If you love salsa, take a salsa class. It will become infectious and you'll keep going back.
I've always been a dancer, and I will always be a dancer.
