Those celebrities seem to have a false idea of what it takes to get to an acceptable standard.
Exactly so. I'm totally against physical abuse, but in dance training it's a case of no pain, no gain. Blood, sweat and tears. If it hadn't been for a very strict, mean-spirited dance teacher, who gave some very cutting comments on our efforts, I wouldn't have won loads of medals and trophies in comps, let alone been on the London stage.
The strange thing was that after a rehearsal or a performance, that ferocious teacher would revert to being a kind and supportive person who accompanied us out to a restaurant to eat, and whose own children were our friends.
