Nadia; A dancer and film actress

Never just dance the steps. Get into the song, and put feeling into it. If it's an upbeat or happy dance, smile, make big, sharp movements, and smile! If it's a sad or emotional dance, make each move slower and use your facial expression to guide your body. That makes every performance a lot better. 

If you want to dance professionally, you typically need to follow specific rules and regulations, most of which are designed to ensure performance precision. Professional dancers primarily work in theatres or professional dance companies with ample space for dance practice. Professional dancers spend a considerable amount of time learning and practising their routines in order to increase their chances of putting on a perfect performance. This can require unprecedented levels of focus, commitment and attention to detail.
