Reading through some GTD blogs and ran across something that made a huge lightbulb go off in my head:
I have adapted this concept of contexts to suit my situation as a home manager. Our week is roughly divided into “themed” days. Monday is Laundry Day, Tuesday is for running Errands, Wednesday is Kitchen Day, Thursday is Office Day, Friday is Cleaning Day, and Saturday is Garden/Yard/Large Project/Family Day.
Aha! All the residual angst around "I need to study for my finals but I never seem to get around to it and I want to just schedule it on my calendar but then David Allen would kick down my front door and beat me with a rubber hose" just evaporated.
If your lifestyle needs more structure and you feel tempted to start throwing non-day-dependent tasks on your calendar, you might need to define up some contexts.
Monday is Laundry Day. Do things from the @LaundryDay list. Weekday lunch-hours are @ExerciseTime, so do things from that list. It strikes me as just the right marriage between "Mon 12:15-12:45: Jog 0.75 kilometers" and "Someday, somewhere, when I feel like it, I should exercise."
I'm in a pretty context-light lifestyle right now (I've only really got 2 or 3) so I think this'll help me considerably.
