This might seem like an obvious tip, but failing to put away your belongings is the main culprit of untidiness. As you move from one room to another, do a quick scan to see if there’s anything that you can take with you. Go out of your way to make sure that anything you wear, use or move ends up where it belongs. It’s easy to leave a pair of shoes near the front door, a few shirts on your bed and some dishes in the sink until tomorrow. Remember, those tiny piles can quickly turn into big messes.
