This month is our 5 year anniversary with Dave. Reading his book and taking his suggestions was the BEST decision we made financially in the nearly 20 years that we've been married. We don't follow him letter by letter, we took his advice and modified it into a plan that works for us. So, now we have only a mortgage debt. But we also have 2 paid off cars (a 2007 & a 2005, both should last a while), paid off both DVC contracts, kicking big amounts each month to 401k, and about 4-6 months worth of expenses sitting in an emergency fund. His plan is not difficult...it's by and large, common sense.
Aside from the financial benefits, it's really helped our marriage because money is no longer argued about...we discuss our goals and then come up with a plan to meet them, together.
