On the outside, Gretchen Rubin had it all--a good marriage, healthy children and a successful career--but something was missing. Determined to end that nagging feeling, she set out on a year-long quest to learn how to better enjoy the life she already had. Each month, Gretchen pursued a different set of resolutions--go to sleep earlier, tackle a nagging task, bring people together, take time to be silly. She kept track of which resolutions worked and which didn't, sharing her stories and collecting those of others. Bit by bit, she began to appreciate and amplify the happiness in her life.
