Query: Vague, Undescriptive, yet strangely confidence building

With advice like "1. Smile".. I was immediately turned off to this book as soon as I opened it. Much of the advice it gives is kinda dull and useless, and few of them are things a normal mental ward patient couldn't have come up with. I wouldn't recommend it, unless you live in a cave, and are unsure what real people look like.
