Do you keep record/paperwork?

I try to. I don't have like files or things like that, but I write confirmation numbers on all paid bills and put them in the paid bill pile. My school work is actually all completely organized and filed and I have printed copies of everything I submit electronically in case there's an issue with the system or whatever, I won't lose points. I also keep all email correspondences with the school. I could certainly be more organized with my personal paperwork though like medical stuff and whatever. That's all over the place and I'd have to dig for it

How about you?
