If you must remove paper documents from folders, it can sometimes be very difficult to locate the file again. Then, you end up having single sheets of paper on your desk that need to be filed. Make it extremely easy and mindless to return items to their original homes by leaving yourself a bread-crumb trail. When you remove a paper from a file, put a Post-it flag in the spot from which you removed the document, and place a matching Post-it on the actual document. This way you don’t have to remember where you pulled the document from and when you go back to put your papers away, all you need to do is match up the Post-its. Three minutes is all it’ll take to return everything to its original home, as you match up Post-it flags.
