Ballet is all about illusions. Dancers trick themselves and their audiences in order to produce a time-honored art form based on unnatural and highly ordered movements and positions. Much of what the audience sees is a trick or a distraction, because what they think they are seeing is impossible. Really, much of what dancers expect of themselves is impossible, because what they expect is perfection. In this quest for perfection, there is pain and often injury, but to a dancer, that is simply part of the cost of creating their art. Dance creates a very different perception of self than another sport or art form, perhaps because it is a combination of both.
