Could you reduce your possessions to 100 things? Would you want to? I love the idea, and I'd love to do it, but only if I can have unlimited books. And that certain things count as one, like "A box of paper samples" or "A box of photos". (In the article, it does mention exceptions for, say, kitchen or communal stuff, and pleasingly, books ) Similarly, one of my college tutors suggested making an inventory of everything you own and documenting it, which I've always wanted to do. It would make you think seriously about everything you had, and what it was used for or what it meant to you, and why you had it. A bit like the guy who sold all his possessions on eBay there's something hugely liberating about starting afresh. I'm a bit of a packrat at times, and keep all sorts of bits and pieces, but oddly if I came home to find the house had burnt down, I don't think I'd be that bothered by any of it. It begs the question if you had to take 100 possessions and leave, (and assume you then had the money to start again), what would you do differently? Would you buy 7 identical outfits so you never had to think about what to wear again? Would you only buy paperback books all the same height? Or would you revel in the randomness of what you'd bought and been given over the years and build up things the same way again?
