Way to go, Vince!!!
I started onthe YNAB Way October 2008, and while we had never been in credit trouble, always paid our bills on time, and lived as we chose, we had several times over charged up big credit card debts and then paid them off with refi's or inheritance or some such.
We realized then that we could never retire unless we did two things:
1. retire the $14,000 credit card debt we had (0% interest, to be sure, but still having to be paid each month)
2. DON'T LET IT HAPPEN AGAIN!!!
What to do? Enter YNAB. At my daughter's suggestion, I convinced my wife to try something we had never done before, in 38 years of marriage; start a budget, and live within it.
My daughter had really managed to mess herself up with credit cards, bounced checks and lying to herself and others (including us!) about her situation. Along came Dave Ramsey and YNAB. Now she's "straight", and about as much fun to live with as a reformed smoker (just kidding, she quit smoking too!

)
As a result, we started budgeting on YNAB, and paying off that credit card at a rate that would allow us, by adding a $6000 cd I owned to the total, pay the whole thing off last month when the interest rate would have gone to 12%. In addition, we built a buffer, rebuilt our sunroom and started an IRA for my wife with the maximum $6000. We could have done it all along; we just didn't know where the money was going, so we let it go.
We now have only two active credit cards, and they are paid each month. Why two? One is a Costco AMEX which gives me low gas prices as well as cash back.
Why the second card ? It's an MC from Kroger, which gives cash back on groceries (our biggest expense), and is accepted everywhere, unlike AMEX. We use it for just about all our other purchases, especially on-line.
Why any cards at all? Like it or not, and I know this upsets the Ramseyites, fewer and fewer retailers are accepting checks, and having been burned badly once by a debit card (which also are not always accepted), I don't want to use one again until there is more protection built in against fraudulent use. My credit union was very sympathetic when some clown in Pakistan got the number and bought $2000 worth of phones on ebay, but they took it to be a legitimate transaction and took the money out of my checking account. So sorry

Fortunately, ebay made it good. With a credit card, I can check my account every day (which I do), and am only liable up to $50. Cash, of course, is almost impossible to use to any great extent, and is harder to reconcile on YNAB (no "third party" account to catch you when you forget to enter a transaction), and is anonymous if it is stolen or mislaid.
BUT YA GOTTA PAY 'EM OFF EVERY MONTH !!! I just hope the gummint doesn't keep "reforming" the industry to where the grace periods go away.
In the final analysis, without self-discipline and a commitment to live responsibly, no software or Plan will work for anyone. But if you make that commitment, and excercise that self-discipline (not self-denial, self-discipline) YNAB will make the job much easier.
Good luck, Vince!
We know you can do it.
