This is a fabulous book and I suggest this to anyone going thru difficult times and you need something uplifting and helpful to get you thru some tough times. The Art of happiness has helped me be more productive and motivated, as well as appreciate life and the people in it. This is by far, my favorite book. Loved it, and I find it soooo useful in everyday situations. Excellent book, from beginning to end!!!!
