Query: Useful even for a non-Christian

This book is certainly Christian-oriented. But I still found plenty of good advice. I've read it over and over, and wish it were longer. What makes this relationship book different from any other one I have read, and I've read almost all of them, is that half of the book focuses on how to look, how to act, how to treat men, etc, but the other half of the book is about being a "girl worth having." This means being a good person, having good values and morals and a positive attitude, not talking badly about people behind their back, not thinking that you're much better or much worse than anyone else, etc. Even if you don't necessarily agree with the value-system espoused in this book, in the world of relationship books, this is radical advice. Yes, it does go on about having good domestic skills, but as this book is outdated and geared toward a certain demographic, you can take this advice or leave it, although I don't know any men that want a woman who can't cook.
