I have heard of the philosophy of not needing a credit history or credit cards, but never really believed it could work for me until I read this book. Ramsey describes many carefully planted myths about money and money management that hurt normal people and benefit companies and how our ignorance of this is killing us financially. We are trained by meticulous marketing techniques to live a lifestyle that will keep us in debt forever (a lesson I've lived personally).
Read this book to get a practical and easy-to-implement plan that will get your personal finances under control. Stop wasting money, stop worrying about the future, stop being a slave to your debts. And, yes, I'm debt free and have been for more than four years now. Never again.
