I agree with -jimi- that I know that many of the people I know who have ADD are perfectionistic, at least in some aspects. Unfortunately, I am not one of those people :P I don't have any real advice other than maybe wait until you get in the mood? I got through spurts where I get super sick of all the clutter and super motivated to clean. I try to make the most of that enthusiasm and try to quickly clean up before I lose interest halfway through. Sometimes I don't finish but at least I make some progress!
