Is it too much of an ordeal to put things away? If you have to go climb a ladder, move a piece of furniture out of the way, or cross the length of your house just to put something away—you'll never do it.
Solution: Store things where you use them to make them easily accessible. For example, if you do your bills in the kitchen, store your financial files and calculator there, not in the spare bedroom upstairs. Look for where your piles are and create storage there.
