Bestselling author of The Four Tendencies and The Happiness Project Gretchen Rubin illuminates one of her key realizations about happiness: For most of us, outer order contributes to inner calm. In a new book packed with more than one hundred concrete ideas, she helps us create the order and organization that can make our lives happier, healthier, more productive, and more creative.

In the context of a happy life, a messy desk or crowded coat closet is a trivial problem–yet Gretchen Rubin has found that getting control of the stuff of life makes us feel more in control of our lives generally. By getting rid of things we don’t use, don’t need, or don’t love, as well as things that don’t work, don’t fit, or don’t suit, we free our mind (and our shelves) for what we truly value.

In this trim book filled with insights, strategies, and sometimes surprising tips, Gretchen tackles the key challenges of creating outer order, by explaining how to “Make Choices,” “Create Order,” “Know Yourself–and Others,” “Cultivate Helpful Habits,” and, of course, “Add Beauty.”

When we get our possessions under control, we feel both calmer and more energetic. With a sense of humor, and also a clear sense of what’s realistic for most people, Gretchen suggests dozens of manageable steps for creating a more serene, orderly environment–one that helps us to create the lives we yearn for.
