Most advice on how to prioritize tasks starts with a ranking method: urgent versus important, MoSCoW, a numbered top three. The methods are fine. They just assume something that is usually false: that the list in front of you is the whole list.
It rarely is. If a third of your commitments are still in your head, in a chat thread, or in an email you have read but not answered, then any ranking you produce is a ranking of the visible third. That is why priorities feel unstable. You keep discovering work that would have changed the order.
Get it all out before you sort
Before you rank anything, do one pass whose only job is completeness. No ordering, no estimating, no deciding what is real. Just empty every place a commitment could be hiding:
- Your task app, including the lists you have been avoiding.
- Unread and read-but-unanswered mail.
- Messages where you said "sure, I'll do that."
- Whatever is in your head right now, including the vague ones.
- The notes you took in meetings this week and never processed.
Write everything as a line, even the items you are certain are trivial. Certainty at this stage is unreliable, and dismissing an item is a decision. Decisions belong to the next step, not this one.
The result is one list that you can rank without hidden commitments changing the order later.
Then sort once, with a coarse instrument
With the full list visible, the ranking method barely matters. Any reasonable one works. What matters is that it is coarse and fast.
A version that holds up:
- Delete. Things you are not going to do. Say so now rather than letting them lurk.
- Two minutes or less? Do them immediately. They cost more to rank than to finish.
- Fixed date? Put it on the calendar and stop ranking it. It is not competing.
- Everything left, into three buckets: this week, next few weeks, someday.
- From "this week", pick three for today. Only three.
Resist a finer sort. A precisely ordered list of nineteen items is a fiction with a maintenance cost: the order will be wrong by lunchtime, and re-sorting feels like work while producing nothing.
Why priorities keep drifting
If you re-prioritise constantly, it is usually one of three things, and none of them is a ranking problem:
- The list is still incomplete, so new work keeps arriving as a surprise.
- You are ranking too finely, so ordinary events invalidate the order.
- The list mixes commitments with ideas. "Rewrite the onboarding email" and "maybe we should rethink onboarding" cannot be ranked against each other. Only the first is a task.
That third one is worth watching. A lot of task lists are half task list and half idea capture, and the ideas make the tasks look unmanageable. Separating them costs nothing and shrinks the list immediately.
Where Capture fits
The completeness pass is only realistic if things were getting written down in the first place. Capture is one always-open field for that: notes, tasks, links and reminders on iPhone, iPad, Mac, Apple Watch and Apple Vision Pro, with nothing to file at the moment you write it.
Because it takes ideas and commitments in the same field, sorting happens later, in one place, when you can tell the difference. On the sweep you send the real tasks to wherever you track them: Things, Apple Reminders, Todoist, OmniFocus and TickTick are among its 54 destinations, each with its own settings.
Capture reads dates out of your own sentence, so "invoice the studio on Friday" arrives already carrying its timing rather than needing to be ranked at all.
If you run GTD, this is the clarify step; the getting things done method starts with capture covers the full loop.
The honest version
Prioritising is not really a skill you get better at in the abstract. It is mostly a function of how complete and how current your list is.
Spend the effort there. A rough ranking of everything beats a careful ranking of some of it, every time, and it takes less work.
