Outer Order, Inner Calm

If you have not read every other Gretchen Rubin book, or you are just looking for some decluttering advice, this may be a good option. If, like me, you've read many of her other books, there is a lot of repetition in this book. It include information from The Four Tendencies and Better Than Before. If I were to recommend just a couple Rubin books, I would choose either the Happiness Project or Happier at Home and Better than Before. If you really just want decision making tactics, then go with The Four Tendencies instead but no one, not even me, needs to read all five?!?
