Happier at Home by Gretchen Rubin. Met the author at a book signing last year (2012) in Kansas City, so I already have this book. I'm hoping this one is just as good as her last book, The Happiness Project.
Getting Things Done by David Allen – The ultimate ‘organize your life’ book. Allen’s ideas and processes are for all those people who are overwhelmed with too many things to do, too little time to do them, and a general sense of unease that something important is being missed. The primary goal of this book is to teach you how to effectively get your ‘to-do inbox’ to empty.
