Avoid Rumination and Change Your Mood

People often ask me what *one* book I would recommend they read. I never had an answer I felt good about until I read this book. It's amazing. The most comprehensive and readable look at what we *scientifically know* works to boost our happiness—from gratitude and exercise to optimism and kindness. (btw: The other #1 book I'd recommend? The PhilosophersNotes workbook. How can you beat 1,000 Big Ideas from 100 great books packed into 600 pages? ;)
