Debt-Proof Living may be known to some of you as Cheapskate Monthly: the site has been revamped and renamed. Written by the money editor for Women's Day, the site is busting at the seams with financial tips - along with personal notes from Mary Hunt about her quest for a debt-free lifestyle.
The Hunts have simplified their lives, and their initial motivation was financial. This may not be true for everyone (my initial motivation to simplify was not based upon money, for example), but Mary Hunt has a lot of good advice and encouragement for anyone in the midst of seeking a simpler life.
It's a great site. I think you'll find things there that you will use.
