"Kierkegaard, the nineteenth-century Danish philosopher, first described what has come to be known as 'threshold anxiety'. He describes the feelings of a young man who is about to leave home to go out into the world to seek his fortune. As he stands on the threshold of the house, about to leave, he feels that he's turning his back on everything that is warm, familiar, and secure -- what he has known all his life. Beyond the threshold lies the world, filled with all that is unknown and strange. If the young man turns back at this point, he is lost. If, however, he can take the fear of the unknown and turn it into the excitement of the unlimited possibilities which are open before him, he grows in the moment and is alive, as never before."
