My dad bought me David Bach's book, The Automatic Millionaire, a few years ago. Granted, it took me a bit to finally get this set up, but after reading the same suggestion in some of the books by Suze Orman, I finally got my act together. I even added an extra 10% to each month's payment to chip away at the mortgage a little faster.
Setting up the automatic monthly payment with my lender was easy and now I need not worry whether or not I have mailed the mortgage check. Hey, and since I am not using a stamp or an envelope, it counts as being green too!
