… is a calendar. In some seasons of my life it’s a physical calendar, in others a digital one (I’m a huge fan of Fantastical, because it unifies my events and reminders in a single app). Basically I have a task list plus blocked-out periods on my calendar to work on specific projects. For instance, this week I’ve blocked out 8-11:30am every day to work on my biography of Paradise Lost. Also, for both events and reminders I use the Notes and URL fields to add information that will help me remember what specifically I need to focus on. (When I’m using a paper calendar, I jot down such details on sticky notes.)
And that’s it. That’s my “productivity system.” It is very simple and very powerful.
