Sloppy, hurried effort
This book does contain some useful suggestions and a superficial review of some psychological studies. It also contains spelling and grammatical errors, a number of meaningless sentences and poorly structured paragraphs. It bears the hallmarks of a hurried first draft and the editors should be ashamed. At least the authors bothered to gather some material together in a loose structure. The editor appears to have abdicated his responsibilities altogether. Try something by Leil Lowndes. She tends to be a bit too breezy for my tastes, but, at least she has made an apparent effort to provide value to the reader.
