―― In my experience, no species of performing artists is as self-critical as a dancer. ...(中略)... each time I've congratulated a friend or acquaintance who is a dancer on a superb performance ―― and I include Baryshnikov ―― I've heard first a disconsolate litany of mistakes that were made: a beat was missed, a foot not pointed in the right way, there was a near slippage in some intricate partnering maneuver. Never mind that perhaps not only I but everyone else failed to observe these mistakes. They were made. The dancer knew. Therefore the performance was not really good. Not good enough. (Susan Sontag "Dancer and the Dance")
