The Happiness Project, by Gretchen Rubin
Can you use more happiness in your life? The Happiness Project, or, Why I Spent
a Year Trying to Sing in the Morning, Clean My Closets, Fight Right, Read Aristotle, and Generally Have More Fun, by Gretchen Rubin, is a great place to start! Gretchen chronicles a year in her life where each month she tackles something different in an attempt to enjoy her life more! What she finds are little changes that add up to big happiness boosts! I read this book years ago and am still using some of her suggestions. I think you will love it!
