One roadblock to getting rid of clutter in my house is that my kitchen is very big, so lots of things get left in the corners of the kitchen.
*Ice chest from a recent road trip
*Easter baskets (long after Easter)
*Reusable grocery bags
*Goodwill donation bag
Maybe your stuff doesn't belong outside. Maybe it is cluttering up your house and belongs in the garage or upstairs. (Oh, stairs, how I loathe thee.)
Whatever needs to go elsewhere, take a minute, and move it to elsewhere. Don't let those things linger and crowd your home.
As an added bonus, once those items are put away, your house will look neater and it will be easier to keep it clean.
