Accent upon: a clear discrimination among countless random 'wants' and some reasonable facsimile of actual? 'need' (modified by the occasional.. Oh WTF, why not?) Life IS, after all about Exceptions [Captain Picard Vol I.] and spontaneity is a deadly price ever to pay for umm 'logical conformity' 24/7.
Frankly too: the scary idea of "giving up" all that stuff: is equally a Red Herring. Once you take personal inventory and discover (don't know how to put it Universally) "what you love VS sorta like" - the triage is not at all unpleasant - it could even be called exhilarating! tossing those useless boxes of saved stuff.
As always YMMV.
Bon appetit y'all. (One lives longer eating small portions, it is said)
