We come into the world with a longing to be known and a deep-seated fear that we aren't what we should be. We are set up for a crisis of identity.
And then, says Frederick Buechner, the world goes to work: Starting with the rather too pretty young woman and the charming but rather unstable young man, who together know no more about being parents than they do the far side of the moon, the world sets in to making us what the world would like us to be, and because we have to survive after all, we try to make ourselves into something that we hope the world will like better than it apparently did the selves we originally were. That is the story of all our lives, needless to say, and in the process of living out that story, the original, shimmering self gets buried so deep that most of us hardly end up living out of it at all. Instead, we live out all the other selves which we are constantly putting on and taking off like coats and hats against the world's weather. (Telling Secrets)
Think about the part you find yourself playing, the self you put on like a costume. Who cast you in this role? Most of us are living out a script that someone else has written for us. We've not been invited to live from our heart, to be who we truly are, so we put on these false selves hoping to offer something more acceptable to the world, something functional. We learn our roles starting very young and we learn them well.
