The 3-Places System
A simple setup guide for Inbox, Calendar, One List and the 10-minute Sunday reset.
Most people don't have a time problem. They have a "too many places" problem: notes in three apps, tasks in your head, reminders in texts, half-finished lists everywhere.
The 3-Places System fixes that by giving everything in your life exactly one of three homes: an Inbox, a Calendar, and One List. Nothing else. Once it's set up, a weekly reset of about 10 minutes keeps it running.
Here is how to set it up.
Step 1: Pick your Inbox
Your Inbox is the single place where anything new lands first: an idea, a task, a thing someone asked you to do. It is not where things live, just where they arrive.
Pick one tool. It could be the notes app on your phone, a messaging app's "notes to self", or a plain notebook. If it takes more than 2 seconds to open, pick something else.
Step 2: Empty your head into the Inbox once
Take 10 minutes. Write down everything on your mind right now: things to buy, people to call, ideas, small worries. One line each. Don't organize yet, just get it out of your head and into the Inbox.
Say someone writes down 25 things. That's normal. The goal of this step isn't a short list, it's an empty head.
Step 3: Set up your Calendar as the only place for anything with a time
Anything tied to a date or a time goes on the Calendar, nothing else. An appointment, a call, a deadline, a reminder to pay something.
Use whatever calendar you already have (phone, Google, paper). The rule matters more than the tool: if it has a "when", it goes here, not on a list.
Step 4: Set up One List for everything with no fixed time
Create a single list, in one app or one notebook page, for everything you need to do that doesn't have a specific date yet. This is where most of your day-to-day tasks will live.
Picture a café owner with tasks like "reorder cups", "call the accountant", "fix the sign outside". None of these need to happen on an exact day, so none of them go on the Calendar. They all go on One List.
Step 5: Sort your Inbox into the other two places
Now go back to the Inbox from Step 2. For each item, ask one question: does this have a specific date or time?
- Yes: move it to the Calendar.
- No: move it to One List.
- If it's not really a task, just useful information, keep it somewhere separate (notes), not in either place.
When you're done, the Inbox should be empty. That's the sign the system is working.
Step 6: Use the Inbox daily, not the other two
From now on, new things always go to the Inbox first, even if you know exactly where they belong. This takes the decision off your plate in the moment.
For example, if someone asks you to call them back next Tuesday, don't stop to open your calendar. Write "call back Tuesday" in the Inbox and move it during your reset.
Step 7: Run the 10-minute Sunday reset
Once a week, usually Sunday, spend about 10 minutes on three things:
- Empty the Inbox: move everything into the Calendar or One List, using the same question from Step 5.
- Scan the Calendar for the coming week: know what's already fixed.
- Scan One List and pick the 3 things that matter most this week.
That's the whole reset. No deep planning session, just keeping the three places honest.
