Of course, you have a filing system in place! Except it’s not up-to-date… You got married, had children, bought a house, signed up for new insurance policies etc. but never revisited it or maintained multiple filing systems in parallel. Or you never purged your files and are no longer able to fit another piece of paper in it so it ends up in a pile or is randomly filed. So how to refresh it so you can instantly find anything you need, without even arguing with your spouse?
