:) Glad it was as useful explanation.
"Oh the tidying a nook only to find it is messy again by the time I have finished the adjacent cranny really describes my house!"
I've definitely always been like this too! Thinking 'oh the shelves look lovely' then turning round to see that the rest of the room/house is filled with the crap komono that's been displaced from said shelves is pretty much my tidying history. I've also been a big advocate for the 'oh my house is a mess, I'd best go to Ikea and buy some more boxes' school of tidying! Oh and the 'I hate the house, I'll do some online shopping to cheer myself up'... oh wait I don't even want to open the parcels as I know I have nowhere to put the stuff... 
So, as a result of these bad habits, I have a lot to declutter. I do think that the Konmarie method is revolutionising my thinking though (hurray!) as I now feel loath to bring any more things into the house as I can see now how it was just adding to the problem.
e.g. I had already costed up and was about to order a new wardrobe for the kids' room so they had hanging space instead of just shelves/baskets, but after reorganising and decluttering mine and DH's wardrobes we had a whole bottom hanging rail free - perfect height for the kids to reach independently and saved about £150 for the new wardrobe & 1m x 58cm in floor space!
