Hermione, Aplaceonthecouch, and OPs I found the comments on 'what's next' usefully illuminating, thank you.
Warning! Heavy post 
My clutter has got out of hand since I retired (from Teaching! My sister's a Translator!) My house is functional (just), but I recognised that all the de-cluttering advice I have read in books, websites and attempted, was not particularly helpful. Until I discovered MK at Christmas!
For some years I have been trying to identify the psychological reasons behind my slump into such a mess. I have made quite a few LB discoveries about myself, but the biggest one was what advantages my messiness was giving me.
Sadly, many experts, say that cluttering results in isolation, but I realised that cluttering protects isolation! I didn't want to be around people!
In the past, the 'noise of clutter' had begun resonating with me, along the lines of the 'cluttering and isolation' theory. Then, the remarks further up-thread brought another LB moment: the 'noise' of clutter hinders our minds, and prevents us from confronting concerns, worries, or issues which we really need to address, or at least, give some thought to. I had seriously considered that the state of my mind had caused the cluttering. No, it is the state of my life and 'what's next', that needs fixing!
I have always had a goal in front of me. Until I retired.
MK has given me a goal. More than that, she (with help from you lovely posters!) has shone a light into a clean, spacious future. My future may be relatively short, with opportunities and cash much, much less, but the possibilities are still amazing.
I need the woo. So thank you for all the little nuggets of wisdom that have resonated with me.
So, today I part-kondoed my head!
