This is the story of how a woman paid off $64k in credit card debt in under three years (without becoming a stripper.) But it's also a study on what led her there, and why it was really the best thing that ever happened to her.
The real goal of the book is not to teach people how to get out of debt (though it does explain in detail exactly what she did), but to help them to analyze their lives and what a big "mistake" like that is trying to teach them, or push them into changing about their lives.
