Query: Verbal flatulence at it's worst

What a terrible book! My wife found it at a garage sale for a dollar and at first I was intrigued... how can you go wrong for a dollar. Now I believe she was overcharged.The book is poorly written by an author who appears to be more interested in promoting the number of "big words" in his vocabulary than providing any insight into giving oneself a mental overhaul. I'll give him this much, he seems interested in the subject matter, but he isn't sufficiently well read to offer his own rendering.My advice to this author is to first learn about the material before writing about it and second, find a publisher who provides professional editing services prior to release.
