The comfort zone is just that a very comfortable place to be, it is a nice warm and fuzzy place that puts no demands on the person. Not much excellence is accomplished there precisely because it is very comfortable. To achieve a high standard of excellence in performance you cannot afford to be in the comfort zone. It is necessary to get uncomfortable, to test yourself and recognize that there are no boundaries. Boundaries and barriers are artificial constructs imposed by those who are comfortable and heavily invested in the status quo. Being limited by boundaries and barriers is letting others define your potential. Working to be the best demands being comfortable with being uncomfortable all the time.
