When the work has piled up and you're staring hypnotized at the impossibly large mountain of need-to-dos our family calls it "going rabbit". The only way to remove the spell is to stop staring it in the eye, get your head down and do a small piece of it. I hate tidying and housework in general so the only way I get moving is to say "I will just tidy away five things." That usually gets me moving enough to do more.
