Do a Weekly Review
Tasks slip through the cracks not because you are lazy but because no one ever looks at the whole picture. The weekly review — twenty quiet minutes with your lists, calendar, and inbox — is the habit that keeps a simple task system alive. This guide builds the habit step by step.

TL;DR / Quick Fix
Quick fix: once a week, sit down for twenty minutes and review everything — your task list, your calendar, and your inbox. Mark what is done, move what slipped, and plan the coming week. This one habit catches the tasks that daily busyness lets slip through the cracks.
Follow these steps
- Pick a fixed weekly slot. Same day, same time, every week — Friday afternoon or Sunday evening work well. A calendar block you defend beats a vague intention to 'review sometime'.
- Empty every inbox to zero. Process email, notes apps, voicemail, and paper piles until each item is deleted, delegated, or on a list. An inbox is a collection point, not a task list — see inbox basics for the method.
- Review last week honestly. Look at what got done and what slipped, without judgment. Slipped items go back on the list with a real next action — not guilt, just a plan.
- Preview the coming week. Scan your calendar for the next seven days. Spot conflicts, prep for big meetings, and move tasks off overloaded days before the week starts.
- Update your project and someday lists. Mark finished projects complete, delete dead ones, and rescue anything from someday that has become urgent. Lists you trust are lists you maintain.
- End with the top three. Pick the three outcomes that would make next week a win and put them where you will see them Monday morning. The review is done when next week has a shape.

What NOT to do
- Do not do the review 'when you have time'. You never will — the slot must be on the calendar.
- Do not turn it into extra work time. Reviewing is planning; answering emails during it defeats the purpose.
- Do not skip weeks because things feel under control. That feeling is the review working — skipping kills it.
- Do not review in a noisy, interrupted space. Twenty focused minutes beat an hour of distracted skimming.
Frequently asked questions
What if twenty minutes is not enough at first?
The first two or three reviews take longer while you clear backlogs — that is normal. Once the habit runs, twenty minutes is plenty for most people.
Morning or evening — does it matter?
Pick the time you will actually keep. Friday afternoons close the work week cleanly; Sunday evenings set up Monday. Consistency beats the perfect hour.
Do I need special software?
No. Paper, a notes app, or whatever task tool you already use all work — a short checklist matters more than the tool.
