The preparation of ballerinas is so intense to see

I can just close my eyes and listen to the sounds of this video about Swan Lake and The Royal Danish Ballet. Or I can just mute the audio and watch the visuals of the ballerinas. No matter how I watch this video, I always walk away impressed with the intense dedication and sacrifice. It's so satisfying to see. » 3/26/15 10:40pm 3/26/15 10:40pm
