I'm particularly excited about this area of organization because I was horribly bogged down with paperwork from everything flying about everywhere and generally found it too overwhelming to do much about digging myself out from it.
This also came from an idea from Pinterest, from this pin as a matter of fact:
...but I really took the initial idea and ran with it to a new level (and I'm not sure I ever actually read that post - the image was really helpful, though!).
Basically what it amounts to is a cabinet dedicated to binders for household and school paperwork (one shelf for each). My modus operandi is basically to dedicate a binder to each area of complex paperwork, i.e. paperwork which can't just simply be filed but that needs to be referenced or attended to on a regular basis. A few of them aren't so much about organizing paperwork per se, but paperwork related information, such as passwords for various websites.
Here is a picture of part of the cabinet (about 1/4 of the binders):
Here are a few pictures of the College Finance binder to give you an idea...
