The best way to keep your sanity when dealing with paperwork is to have a system in place that takes away any guesswork. My system is to have four places set up to organise paperwork – a place for short-term items, transient items, long-term items, and permanent items. Then it’s a case of adopting some simple habits to maintain this system. This doesn’t involve much other than making sure papers go into one of the storage areas straight away – if it is set up right, this should be a quick and easy task. Anything that needs to be scanned and filed in a particular way goes into the “transient” storage space to deal with later. Then once or twice a year, you will need to go through the transient storage space to scan the items for electronic storage. I find it doesn’t take much effort to scan and electronically file paperwork away. I personally can get away with doing it once, maybe twice a year, and it takes maybe half an hour at the most to get my yearly paperwork in order.
