I seem to be taking advantage of the fact that GTD allows you to easily procrastinate the "big rocks" - that is, during any given period (week/month), there are several projects/tasks that are really the high priorities - that I really should be working on. However, their tasks just end up being one among many in my lists, and don't stand out in any special way. So, once i'm pulling from my list in "do" mode, there's nothing to prevent/encourage me to pick those tasks rather than any other task. So, I'm "productive" in that I'm doing something, but not necessarily picking those tasks that are rolling up on me.
Is there a GTD method for handling this? Have people come up with their own way of handling this? I was going to try to come up with some way of doing it during the weekly review - kind of a punch list with high-priorities or calendaring it, but that sounds a bit like the way Covey suggests.
