Kate's been reading a book by KonMari. Hence we've rehomed lots of clothes, books and DVDs to charity and various places.
I am told the key is to ask, "Does this item bring me joy?" Then if it doesn't bring you enough joy, it goes. The nice thing was, it was actually exciting to reveal the gems among my bookshelves, which were previously hidden by a load of second-rate books.
True story: I was sitting downstairs deciding whether to splash out £25 for a particular book. Was called upstairs to make some 'joy decisions', and saw the very same book on the shelf already. Fast delivery!
