These kinds of books are always mixed bags. There are lots of tips, out of which maybe a few are applicable to any reader. Most readers know half the stuff, and the rest is irrelevant. Even so, there are things to be reminded of, and just the backstory of the writer to be inspired by. If you have no idea of how to save money, then, of course, this book will be a good one, one to get you off to a good start.
