“We build sandcastles of our loves and fancy them fortresses of granite, then watch bewildered as the waves of our inconstancy lap them away, along with the footprints of the builder. Each love we love and unlove alters the way we walk through life, alters the trajectory of our traversal along the shoreline of the self. The only constant is that we go on walking, that we remain pilgrims of possibility. We would not walk if we had already arrived. We would not write if we had already arrived. Out of our incompleteness and our disorientation, out of our longing and our wanderlust, arises the motive force of every love and every revolution, of our science and our art, of our creation and our self-creation. Every creative act is an act of traversal.”
