Thanks for the advice. I love everything in a creepy sort of rainbows and happiness sort of way, I can justify keeping anything and everything. It’s not that I have any problems cleaning. Quite the opposite, in fact. I have places for everything, it’s all tucked away neatly.
But- it’s still there. I am having troubles with the emotional attachment… and things such as the shoe box half full of pens that don’t work but still have ink in them so they might work again someday how could I possibly throw them out! It’s not that its not organized, neat, tidy, and colour coded, it’s that its there at all.
I also highly recommend cranking some good tunes and getting your dance on while cleaning; however, some with ADHD tend to get (gasp) distracted and completely forget that they are having a cleaning party and not a dance party
