The contemplation of beauty, whether it be a uniquely tinted sunset, a radiant face, or a work of art, makes us glance back unwittingly at our personal past and juxtapose ourselves and our inner being with the utterly unattainable beauty revealed to us.
Vladimir NabokovTo a greater or lesser extent there goes on in every person a struggle between two forces: the longing for privacy and the urge to go places: the introversion, interest directed within oneself toward one's own inner life of vigorous thought and fancy; and extroversion, interest directed outward, toward the external world of people and tangible values.
