I'm an avid follower of The Voice. This season the coaches' theme seems to be "Know who you are." Based on the genre the contestants choose, the music they choose within the genre, and the persona they present on stage.
Not easy advice. If we continue to learn and grow, we must continue to adjust our self-images. Like children whose shoes fit fine yesterday, we don't become aware of the need for a new image until the old one begins to constrict us.
Unlike children, who know when they need bigger shoes, adults tend to rationalize their discomfort. We blame ourselves when the towns we live in or the jobs we have become too small. When the people around us no longer understand what we're interested in or what excites us. We try to fit into the outgrown shoes instead of shopping for new ones.
As in any creative process - for we are always creating who we are - frustration and pinching is often what we need to re-assess ourselves. Who have I become? What will feed this new person? Who will make room for me?
