If you are amused and mildly disgusted by the self-help genre, Jennifer Niesslein's Practically Perfect in Every Way is the perfect book for you.
In Practically Perfect, Niesslein decides that something is missing from her life, and that self-help may hold the key to happiness. To make things more interesting, she decides to write a book chronicling her experiences. The result: lots of sarcastic humor, but also a good, quiet look at why self-help is overrated.
The book focuses mostly on self-help in the areas of the household, relationships, and parenting. (If you think Feng Shui is kind of silly, like I do, you'll especially like the commentary in the first chapter.) As you near the end of the book, Niesslein obviously starts losing steam. She is not as gung-ho in her experiments, but at the same time you start getting more down-to-earth, insightful observations about self-help.
The very last chapter of Practically Perfect is my kind of chapter: Niesslein deals with the issue of The Soul. In doing so, she delves into the world of religion, but she also talks a lot about why she isn't particularly religious — something I can totally understand. It is fitting that this is the last chapter, because by this point Niesslein has decided that taking every one else's advice is a really bad idea.
To conclude, I would like to post a quote from Niesslein's chapter on The Soul, one that pretty much exemplifies her humor and the way she came to view self-help:
Are my morals proof of the existence of God? If anything, they seem to me to be proof of the existence of my mother.
Truer words have never been spoken.
