A.M.
I have taken a few classes from Professional Organizer Laurie Reeve. She has a website www.simplyinorder.com and she teaches classes. The Jordan School District Spring 2008 catalog lists her as teaching two classes. One on March 25 and one on April 15. You pay $10.00 and go for 2 hours one night. I have really liked a lot of her ideas. She also has one on paper filing. You have to register for these classes on March 18. Email me if you need more info.
One thing Laurie Reeves teaches is to divide your house into zones and assign one zone to each day of the week to focus on.
Then give yourself a time limit. That has helped me to not be too overwhelmed.
Also, many orangizers teach that you should give yourself a morning routine and a night routine and stick to them until you do them practically in your sleep. For example, my night routine is sweep the floor, start the dishwasher, and get the mail. If I can do those three simple things each night than in the morning I find it easier to focus on my simple morning routine of unloading the dishwasher, making beds and feeding the pets.
Everyone has their "hot spots" where clutter just naturally collects. Pick one hot spot a day to de-clutter. Give yourself a time limit. Turn on some music. Then sort everything into boxes using the TRACK method:
T- Toss (garbage)
R- Relocate (goes in another room)
A-Action needed (mending, needs to be returned, etc.)
C-Charity
K-Keep
Try house organizing books like "Clutter Clutters", "The Healthy House Book," "Speed Cleaning," and "Sink Reflections," "No Time to Clean."
Hope this helps. Good luck!
