Here is my system, which combines many things I have developed over the years. Note, I use it almost exclusively to keep up with things at home. I am a teacher and don’t use it for that.
In my task document, I have a project called monthly tasks. In this project I have about 25 to 30 things I do every month, sometimes once, sometimes twice. They are relegated to “weeks” with tags of 1st, 8th, 15th, and the 22nd which is the date I want them to “start”. These are things like, “Change all filters”, “Clean the blue cabinets”, “Nutmeg Pill”, Cat medicine". Basically just maintenance stuff I do every month. My second project is called “Tasks”. This is a running list of tasks that I do regularly throughout the week. I include nearly everything that I do that are not tied to specific times or date–everything. Dust, Dust Mop, Mop the Kitchen, Work on School Stuff, Straighten, Clean the Kitchen, Laundry, Put Away Laundry, Read a Chapter, Take Blood Pressure, etc. These are tagged @task. I work these following guidelines from Mark Forster (http://markforster.squarespace.com). Basically anything I want to do gets added to the list. If I mark something done, and it needs to be done again sometime, I retype it to the end of the list.
So I have five saved searches. The format is this
@task or @15th except (@start >[d] today or @done <[d] -5 days)
I use this particular search from the 15th to the 21st of the month. It shows me the monthly tasks tagged @15th, all tasks tagged @task, but excludes anything that has a start date after today and any done tasks more than five days ago.
I use a style sheet that shows the today tag in red.
Here is my (or Mark Forster’s) weird but effective system. I scan the list from top to bottom, reading quickly, marking with the tag @today 3-5 items that I am feeling no resistance to doing. I then do those, from bottom to top. Repeat.
The idea is that every time I repeat, I am re-reading each task, which lowers the resistance of some of the tasks I am not doing. I find that the things I procrastinate over still get done in a reasonable time.
When I have finished that week’s monthly tasks, I take off the done tag (so I don’t retype these) and click on my 5th saved search, which just shows me my @task tags.
