All the world's a stage, and all the men and women merely players: they have their exits and their entrances; and one man in his time plays many parts, his acts being seven ages, so says William Shakespeare. As we go through life, most of us are reinventing ourselves, trying to stay fresh, current. Liberals sometimes become conservatives, and conservatives liberal. The young become old. Old likes may not be liked anymore. Roles we could not have imagined playing in our youth are now the ones we play. We evolve. That is human life. The Dao changes form and shape and so do we.
