prettymess I'm a qualified Librarian (as well as a teacher) and I shocked myself several years ago. I have hundreds of books, but when someone asked me which I would choose, between my books and my computer, I said, without thinking, my computer! Eek!
I am happy to re-home the novels that I read, but kondoing any non-fiction (by far, the majority!) will be very difficult. 
KnappShappeyShipwright Your comment on camping chimes with my experience of holidaying in mobile homes. It always confused me - I had no problem keeping a caravan tidy (even with my 3 youngest DC in tow), and it took no time at all to pack up all our stuff and clean round when we left... so why couldn't I do that at home? 
Today, I had another go at the 'maybe' clothes. Not as ruthlessly as I intended, but I've since had 2 LB moments... 1) the insurance premium that I was paying till last week, can be used to buy good quality replacements, if necessary; and 2) I have, at least, 4 lots of quality wool knitting yarn in my stash, earmarked for 'me' sweaters! Tomorrow, I shall stick all the 'maybe' garments in the CS bag, along with (most of) the fear of the future! Reeeeesult!
