Many years ago, I took a modern dance workshop where we were assigned to create a piece of choreography given one instruction, that the dance be on a straight line, and we weren’t to move off that line. After stunned silence, processing this nonsensical limitation, we slowly, tentatively engaged this challenge, and what happened was magic. We were taught that our own ideas about the way something SHOULD be IS the limitation. The exercise forced us to open to new ideas, new possibilities, and new ways of expression, which we never would have otherwise, and in so doing, expanded our worlds. The key was that we were willing to be challenged and opened in the first place.
