I see a lot of “GTD” projects that are mostly prioritised todo lists. But priorities aren’t part of GTD!
In GTD what matters is context. And TW is great for context. So you can tag your todos with @2min for short jobs, @errand for jobs to do on the road, @phone for things that require a phone, @am for things that require your morning brain, etc.
I currently use a system of templates for each major tag of Todo, TodoDone, TodoLater. I can drag and drop items inside the list for pseudo-priorities. Items in TodoLater are dated in the caption field and sorted accordingly so I’m reminded at the start of a month of upcoming birthdays, etc. I have checkboxes to help move items back and forth between Todo, TodoDone, and TodoLater as needed (since many tasks get re-used almost daily).
