"Life is a train of moods like a string of beads, and, as we pass through them,they prove to be many colored lenses which paint the world their own hue, and each shows only what lies in its focus. From the mountain you see the mountain. We animate what we can and we see only what we animate. Nature and books belong to the eyes that see them. It depends on the mood of the man, whether he shall see the sunset or the fine poem."
-- Ralph Waldo Emerson
