I know how overwhelming it can be to get started. Lists of things that need to be done and tips on how to do it are very helpful, but they don't really provide motivation. You end up putting it off and off, then you take a day (or more) to clean, scrub till your skin just about falls off then crash and burn! Then it just builds back up again.
If this sounds like you, check out www.flylady.net
for the solution (free). She can be used hand-in-hand with mrsclean's excellent help and tips to get your house clean and keep it that way, in just 15 minutes a day. Really! She's helped me (and I'm not in any way directly affiliated, just found that it was what I needed to get my house under control and hope to do the same for you).
The basic premise behind FlyLady is that your house didn't get cluttered or messy or dirty in a day and won't get clean in one either -- and if it does, it won't STAY that way. Baby steps help build habits and routines that keep your house looking great all the time -- but you have to stick to the baby steps and not try to clean it all up at once, only to crash because you are sick and tired of cleaning! She sends daily emails to remind us to do small tasks like cleaning our sink, wiping down the bathroom, and decluttering for 15 minutes.
Anyway, I'm sounding like a commercial, and I don't mean to -- I'm just amazed at the difference it made for me and hope it will make a similar change in your life.
