I've tried every planner, app, and system out there. Bullet journals, GTD, you name it. But the one thing that finally made a dent in my chaos was a simple weekly review. Not the fancy 15-step version you see on YouTube. I'm talking about a 30-minute block every Sunday evening where I sort through the mess of my week. It took me three tries to make it a habit. Here's what finally worked.
My messy, imperfect system for a weekly review that works

A weekly review is a 30–60 minute session where you look back at the past week and plan the next. It helps you stay on track with goals, clear your head, and avoid repeating mistakes.
"Three years ago, I was a project manager at a small tech startup. I had 15 direct reports and a to-do list that never ended. My Sundays were spent dreading Monday. Then I read about the weekly review in a blog post by a guy named Carl Pullein. I tried his system, failed, tweaked it, failed again. Finally, I stripped it down to the bare essentials: a notepad, a pen, and 30 minutes. Now I do it every week without fail."
Most weekly review advice is overwhelming. You're told to review your goals, your calendar, your inbox, your projects, your someday/maybe list, your reading list, your habits, your finances... it's too much. No wonder people give up. The real problem isn't that you're undisciplined — it's that the system is too complex. You need something that fits your actual life, not some guru's idealized version.
🔧 5 Solutions
Check your past week's calendar and next week's calendar for conflicts and forgotten commitments.
-
1
Open your calendar — Use Google Calendar, Apple Calendar, or whatever you use. Look at last week's events one by one. Ask: Did I attend? Was it useful? If not, why?
-
2
Delete or reschedule missed events — I use the 'reschedule' label in Google Calendar for anything I missed. If it's not important, delete it. Be ruthless.
-
3
Preview next week — Scroll through the next 7 days. For each meeting, ask: Do I need to prepare anything? Is there a conflict? I write prep notes directly in the event description.
Process your email and messaging apps to clear mental clutter.
-
1
Open your email — I use Gmail. Sort by 'Unread' first. Go through each email. If it takes less than 2 minutes to reply, do it now. If not, archive it and add a task to your to-do list.
-
2
Process Slack/Teams messages — I have a 'Follow up' folder in Slack. Move any message that needs a response later. Reply to anything urgent. Mute channels you don't need.
-
3
Unsubscribe from 3 newsletters — Every week, unsubscribe from three newsletters you never read. I use Unroll.me for this. It takes 30 seconds and reduces inbox clutter over time.
Review your to-do list and move unfinished items to next week or delete them.
-
1
Open your task manager — I use Todoist. Create a filter for 'Overdue' tasks. Look at each one. Ask: Is this still relevant? If yes, reschedule to next week. If no, delete it.
-
2
Review 'This Week' tasks — Go through tasks you planned for this week. Mark done, reschedule, or delete. Be honest: if you haven't touched it in 3 weeks, it's probably not happening.
-
3
Pick 3 tasks for next week — From the rescheduled pile, choose exactly 3 tasks to be your 'Big 3' for next week. Write them on a sticky note and put it on your monitor.
Write down 3 things that went well this week to build momentum.
-
1
Grab a notebook — I use a simple Moleskine Cahier journal. Open to a fresh page. Write the date at the top.
-
2
List 3 wins — They can be small: 'Finished the quarterly report', 'Had a good conversation with Sarah', 'Went to the gym twice'. Be specific.
-
3
Write one lesson learned — What would you do differently? Example: 'I should have asked for help earlier on the budget spreadsheet.' That's it. Close the notebook.
Identify what drained your energy and what boosted it, so you can plan better.
-
1
Review your week's events — Look at your calendar and think about how each event felt. Rate each from 1 (draining) to 5 (energizing). Be honest.
-
2
Identify one pattern — Example: 'I noticed that back-to-back meetings after 3pm leave me exhausted.' Write it down in your notebook.
-
3
Make one small change for next week — Example: 'I'll schedule a 15-minute break between meetings after 3pm.' That's it. One change per week is enough.
If you've tried a weekly review consistently for a month and still feel overwhelmed, or if you're missing deadlines and losing sleep, it might be time to talk to a therapist or coach. Chronic overwhelm can be a sign of anxiety or ADHD. A professional can help you build systems that work for your brain, not against it.
Look, the weekly review isn't magic. Some weeks you'll skip it. Some weeks it'll feel like a chore. But over time, it builds a rhythm that makes everything else easier. I've been doing mine for three years now, and I still have weeks where I'm scrambling. But I've never regretted the 30 minutes I spent on Sunday evening sorting things out.
Start with just the calendar sweep and the wins journal. That's enough. Once that feels natural, add the inbox sprint or the task reset. The key is to keep it simple enough that you'll actually do it. Your future Monday-morning self will thank you.
