The key to making cleaning your office easy is to put everything in its rightful place. So, this means that you need to assign a place for everything and label it clearly so you can find it in a pinch. Once you get in a habit of putting things away, decluttering becomes a quick task that's second nature. This also means not filling up every single inch of storage. New items will come into play and need a place to live, so keep a few empty shelves or drawers to make room for the new.
