I followed FlyLady for a while, but I go in phases. I find it easier when we're on a regular schedule, but it all seems to go out the window in the summer when we're out of town a lot, and the kids are here all day, messes seem to follow them. I've also enjoyed Francine Jay's book The Joy of Less : A Minimalist Living Guide. While I have no intention of becoming a minimalist, it has great hands on tips for reducing your clutter, and streamlining every room in your house.
