I just started to pack up my class for a move to a new building. The stuff I have accumulated is insane. I see how people who retire can just leave it behind. I have gifts from former students, tons of teaching books, classroom decorations, games, and the list goes on. I would like to start with a semi clean slate, but how do you figure out what to throw away? I'm a bit of a hoarder if you can't tell. If you have ever moved classes how much did you purge?
