I'm quite obsessive about organising stuff, especially computer files.
I'm currently on a work experience placement, and over the last week I've been going through something around 1500 microsoft office documents made by various people and renaming the filenames to a set standard. It bugged me that they'd managed to create so many without any particular filename format.
I used to alphabeticalize my cassettes too.
I like this particular trait, makes it easy to find stuff later.
