I would rehearse it differently each time. Maybe it would be awful, but it would be an option, so that when I got out on stage, if the dictates of the moment required it, I had what I called my bag of tricks that I had been through, and you just store them up for the time when they will come in handy. Otherwise, you are rehearsing an opinion, if you do it the same way all the time. If you rehearse the ballet the same way all the time, if you write the same essay, if you draw the same little ponytail, if you do everything the same, you are rehearsing an opinion, and before you know it, you can’t change.
