Given the response to clutter I am ever so glad that none of you have seen my workshop! As far as writing goes, I think that none of my 'stuff' would assist me in that venture - although I did think a few months ago that I might attempt some sort of novel. I did - it's still on page three! Perhaps some sort of regime may help (both subjects); maybe save one hour per day for each? This would mean the workshop should be cleared and tidied by 2020 and a manuscript organised by, say, 2005. Hmmm. ;-)
I've just about cured myself of (a) keeping any bit of paper with spare space on it, and (b) thinking of butter as a luxury. Result of an immediate post-war childhood when these items were a bit short, to say the least.
Ridiculous collecting of piles of junk is a common symptom of OCD. I have OCD and overpowering urges to do that kind of thing, but fortunately I have it more under control these days - although my collection of old Tube tickets amazes all who are fortunate enough to gaze upon it. I think the secret is a sort of displacement - if I focus on collecting a single kind of crap, I can throw away things like receipts or old cinema tickets with relative ease.
I've taught myself how to do it over the years - part of the solution is to recognise when you're in a mood to throw out emotional baggage, and the stored crap associated with it. Anything I haven't used in the past two years is unlikely to be used again, so it goes either for recycling or to charity. There are exceptions, of course - my reindeer skin, pocket TV, tennis shoes and velvet coat. I *hate* small bits of paper and get rid of them ASAP.
