It can be very helpful to read about other peoples experiences with de-cluttering their homes. There are so many helpful tips out there on the big Wide World Web and I will explore more of them and add some more links on my page as I find time.
I have noticed while reading a few over the last couple of days that the biggest mistake for most people is setting to0 high goals. I believe, one day at a time, one room at a time, one drawer at a time are often goals easier reached and less daunting to consider.
Do what works for you and if something looks too much to handle move to another area that you feel more comfortable with. Some days you will be keener than others tackle the big jobs then.
Today while writing my blog I scanned my craft area knowing that there must be something there that could go. I found an old binder with school photos in. I have three perfectly good photo archive boxes that these photos could easily fit in, so I moved the photos to there and have put the binder in the donation box. Now I have a nice space where I can put the birthday card file that has been crammed somewhere else untidily for months.
