" There is no absolute formula for happiness—each unique condition of life can serve as the foundation for happiness in its own unique way. You can be happy when married with children, or when married without children. You can be happy when you are single, without a college degree, or with one. You can be happy when you are slim, you can be happy when you are overweight. You can be happy when living in a warm climate as in California, you can be happy when living in Montana, where you have severe winter conditions. As a sumo wrestler, you can be happy when you make it to yokozuna, or you can be happy while remaining one of the underdogs all your career, doing small chores, never giving up. "
