Professional organizers are advising people to get rid of certain items to reduce clutter and free up space. The number of items recommended for disposal varies, with some sources suggesting 4, 5, 6, 10, or 12 items, but the goal of decluttering is consistent. It appears that organizers are emphasizing the importance of purging unnecessary items, although there is some disagreement on which items are essential to keep and which can be discarded.
