A daily spiritual practice that you enjoy doing will help to increase your happiness score. The essential aim of any spiritual practice—be it meditation, prayer, yoga, tai chi, etc.—is to help you remove the blocks to the awareness of the happiness that already exists in the center of you. Spirituality connects you to your "being" so you don't get lost in going, doing and having. It helps you to identify with the idea that the soul is joy, and to realize that you are what you seek.
