"A clever system charmingly and convincingly explained."

—Starred Library Journal Review

"Gretchen Rubin's four tendencies framework won't fully explain you or everyone around you, but once you're in possession of the possibilities (Upholder, Obliger, Questioner, Rebel) you'll want to analyze yourself, your partner and anyone else who springs to mind, and you'll find you're much more able to understand (and maybe tolerate) their quirks, as well as motivate and be gentler on yourself. Informative and, like all the best analyze-yourself-and-others books, irresistible."

—KJ Dell'Antonia

"Gretchen Rubin explains her well-researched, home-grown four-tendencies matrix in a conversational tone. Her casual style gives listeners the sense they're hearing advice while having a cup of coffee with a friend. Rubin uses changes in pitch and speed to help to differentiate the many anecdotes sprinkled throughout the book. Read by the author, this audiobook delivers a thorough examination of how and why we make our daily choices."
