Ever notice how hard it is to turn off the computer, the TV, etc., when you have de-cluttering to do? Day after day the "to do" list gets shifted to the next day and the next and the next! The rewards may be great, but procrastination inevitably prevails. A dab here, a dab there. An "electronics diet" may be in order until the house is made ready for sale. So much energy expended on the big projects, and now only to find the motivation to deal with the minute and the profane. Starting with something major that can be shoved into big black bags and hauled to the curb may help. And this room is only a sample! You should see the basement. As the kids say, OMG!
