How do you plan habits that need to happen only once in a while like going through your closet or clearing paper clutter?

I have a “power list”. One of my weekly tasks is to spend 30 minutes working on the power list. At that time I pull out my list of all the random things that need to be done and work my way through the list as quickly and with as much focus as I can during the time allotted. Then I stop until the next week.
