This book usually works only for couples who have communication problems. If you're looking to fix "bad attitude" problems of your girl/guy, this book is definitely far away from being your bible.

You guys are funny, making a big deal over the smallest achievements.

Back to the topic, I've read the book and to me it still can't deal with the main issue with most relationship and won't even solve 20% of the issues here in cupid corner. Attitude problem. You can be applying all the concepts in this book but if the girl has attitude problem or is materialistic, I'm willing to bet this book will not help at all.
