I'm currently reading this book, and am really enjoying it. It's a light hearted, joyful description of one woman's journey towards more happiness in various aspects of her life. And in turn, she brings more happiness to those around her. I think the saying really is true: "If Mama ain't happy, ain't nobody happy." Ha!
