Good looks depend on one’s sense of humour. Joyfulness keeps the heart and face young. A good laugh makes us better friends with ourselves and everybody around us. A light heart lives long. There is little success where there is little laughter. Hobbies provide good balance between work and play for those who are intensely bent upon success toward their goal. Those who face life with a feeling of security are much happier than those who face it with a feeling of insecurity.
