That reminds me of another paper system I used for a while. Add new tasks to the page. When it fills, write all unfinished tasks on the next page, and mark them with a star to show they've been moved. Next time you move tasks, do NOT move tasks that were starred. Basically, it's a tacit admission that you're not going to get around to it. This is good, because for most of us, our true to-do list is deeper than our ability or will to finish it. Deleting the backburner things helps reduce guilt.
