I have all my lists set up and my calendar only includes date/time specific appointments. If that is all that is on my calendar, how do you ensure that you have time blocked out for working on project action items? Do you schedule that on your calendar during the weekly review? David's book references pre-defined work. When is pre-defined work identified and how do you ensure that you will have the block of time you need to keep priorities moving forward? My fear is that if you don't schedule an appointment with yourself, that that time will get sucked up by less important matters. How are others dealing with this?
