I ran across her book a year ago and thought it was pretty well thought out. I’d long spent a lot of my life and time and effort trying to just generally get rid of things (often including ones that brought me real joy). Keeping things that bring me joy was a lovely revelation; it was pretty easy to get rid of the rest.
I ought to do more frequent tidying, but having done a major purge last year just before I moved into a new house has made a huge difference in my life and general happiness level.
