Being a dancer I've got the idea that through discipline and hard work, you can develop the ability to be in a different dimension within seconds. You can be vomiting, you can detest who you are, detest the world, detest every single thing, and the next moment you are in the light and you glow. You forget everything, and you are just flying. When you're onstage, you are someone else. Beyoncé is very conscious of this. She said to me, "I'm another person when I'm onstage." And I said, "Oh yes, you are! You are an animal when you are onstage. You are a stage animal."
