Query: Far and away his worst book- don't bother

Very slow, very boring and very, very self-congratulating. Probably hurt his arm patting himself on the back so much. I'm a huge Mandino fan but I couldn't get past this bit of braggadocio. Fortunately, I got the book as Christmas present(yes, I asked for it), so I don't feel as cheated as I would if I'd have bought it myself. How the author of such great books as The Christ Commission and The Greatest Salesman in the World can put out such garbage is beyond me. DO NOT BUY THIS BOOK
