Query: From disappointment to gratitude

When I first recieved this book, I was put off by the layout with some pages only having a line or two on them--like a poetry book. But then I got into the content. In just the first 50 pages, the author displayed different takes on things that had puzzled me for years and that no other self-help book had revealed to me before. Priceless stuff.
