Buy the book, too.
Format: Paperback
Somehow I got confused that this was the book AND the workbook; it is not, you must buy each separately. But from what I've read so far, the book says "out loud" what I've frequently thought to myself or felt in my heart. Wish I'd had this 40 years ago!

Disappointed
Format: Paperback, Format: Paperback
The item was a new purchase. However, several pages were folded; it's a journal that goes with the other two books I purchased.
