I'm a Professional Organizer and I have never watched these shows. (I don't do TV).
They seem to me to diminish the aspects of "getting organized" that really matter. Those being a desire to set a plan in place, designing it for you personality and organizational style and working on "follow through" to make sure the new habits stick.
The shows "sound" great, but yeah, give me enough money and I could do someone's house proud in three days. Come back in three months and without education they're right back where they were. Great for us to watch, (I assume) but not so helpful to the individual.
UNLESS they were paid enough money to work with a PO (or a therapist if their issues required it) after the "TV people" decluttered their home. Decluttering is time consuming and can be painful, but the discipline comes in when you implement the strategies YOU need to STAY organizes for the long term.
Off soap box!
