The only thing I bought this year was a plastic folder covered in goldfish cos I thought it was class. I have so much stuff left over from A Levels...true to my geeky form, I did go through it, sort it, and write up a list of everything. But only so I didn't wander into Paperchase and buy stuff 'in case I don't have it.'
Each subject teacher in my old school gave us a lever arch file, but I never filled all of them. So I have six empty ones, just waiting for lecture notes. The joy...I think the only thing I need more of is file paper, narrow ruled. I go through that like crazy.
I'm going to try and use up the blank notebooks I've collected and never used. Not lecture notes, but just scribbles, or shopping lists, or projects. I have to get out of the way of buying notebooks and not using them, aargh...
