Avoid all thoughts of the untrue, the sad and the depressing. The optimists keep their eyes always on the higher values; the pessimists slide down into the dispiritedness and despair. At nights optimists look up at the starlight; the pessimists look down and grumble at the darkness around them. The optimist draws confidence and courage from the twinkling of a myriad lights on high. The optimists have their eyes only on the flower on the rose plant. The pessimists see only the thorns under the flower, and fear of thorns results in rough handling so the petals of the lovely rose fall off. Seeing a glass half filled with water, the optimist is glad that it is half full, while the pessimist is sad that it is half empty. Though both statements are correct, the optimist hopes to fill the other half too, while the pessimist gives up in despair. The one has faith; the other has no faith. We must develop faith by steady effort. (Golden Age, pp. 277-278)
