Buy a filing cabinet and file everything you want to keep for your records. Mark the tabs very specifically such as: electric bill, car insurance, receipt's, health insurance, etc... Once you have this in place make a conscious effort to file it away. A few other suggestions are plastic storage bins. The clear plastic bins are great because you can see through them, they stack very neat, and you can write on the outside what the contents includes.
One last thing to do is to stand over the trash can as you go through your mail. I know that sounds very elementary, however, if you get your mail and through it on the counter it starts to build up to a leaning tower of mess. When you open up ads and junk mail toss it right away and say good bye to extra "clutter" you do not need. An organized living
space is now in reach! A clutter free space is always a healthier place for you and your family.
