Query: NOT a self-help book

The authors of this book obviously wrote it for other like-minded professionals (and those seeking to make psycholgy their profession). It's nowhere near readable as a self-help book. Unless you're a psycholgist-in-training, don't waste your time or money with this one. If you're going to look at it from an academic standpoint, then this is the book for you!
