While online today I noticed a very good article on things to throw away. It's amazing the silly things that get away from us. I am guilty of holding onto a few of the things on the list because, like most people, I can find a purpose for them.
For example, stained towels with holes. I can use them for the dogs, to wipe down the car, to wrap outdoor faucets.... but do I? And do I really need a bunch of them? No and no. At least once a week I pick a drawer, cabinet, closet, my purse, wallet, something... to go through and clean out. If you can take 5 minutes and make this a habit you will be much happier.
Read this article from MSN for suggestions of what to toss. It's pretty good.
