Every task you own is really answering two separate questions: is it urgent, and is it actually important. Most to-do lists collapse both into a single sort order — due date, or the order you typed things in — which is why the loudest, most urgent thing always wins, whether or not it matters.
The matrix keeps the two questions separate, which is what makes it useful. Do Now is urgent and important — it gets today. Schedule is important but not urgent — this is where the real compounding happens, the strategy work and the workouts that never scream for attention but decide how next year goes. Delegate is urgent but not important to you specifically — someone else should own it. Eliminate is neither, and the matrix's whole point is giving you permission to actually drop it.
Prioro puts all four boxes on one screen, sorted the moment you type a task, so the sorting itself takes no extra step.
