I used to have OCD.  Legitimately, diagnosed by a psychologist OCD, not internet hyperbole OCD.  It made cleaning and purging harder!  Because I had the perfectionist streak so bad, if I couldn't do it perfectly, I'd be utterly overwhelmed and not be able to do anything at all.
That's why I could "perfect" micro spaces - I could Tetris a closet, say, or keep my desk at work and the filing cabinet hyper organized.  I once was hired for a temp job where it was literally "please make sense of our donations room" which was just piles of donated goods to the organization.  I made it into a little store where clients of the org could shop.  The marketing person wanted to hire me permanently just for that.  LOL
But my apartment?  Total disaster.  Because it was too much.
So, I had to nix the OCD - which I have, thank the Gods - in order to even begin to tackle this.  It's a very, very good thing that I can purge. ^_^
