To maintain a positive attitude make it a point to recall times when you have experienced pleasure, comfort, tenderness, confidence, or other positive emotions.
You can increase your mental fitness by daydreaming. Close your eyes and imagine yourself in a dream location. Breathe slowly and deeply. Whether it’s a beach, a mountaintop, a hushed forest or a favorite room from your past, let the comforting environment wrap you in a sensation of peace and tranquility.
