My guess is since this is Psychology Today you would not want to overlook ADD as a major limiting factor in many adults' lives; or the medical illnesses which cause people to be too tired to engage in organization tasks. I love being organized, but find procrastination is common for me, either due to hypothyroid fatigue, or ADD, which causes me to vacillate between over-organizing and not interested. Although I realize it was not the purpose of this article to talk about ADD, a simple mention of it as a major factor in organizational skills would be comforting to those of us who have it.
