Leave a note for the person who comes back to this

Last time: The smallest day that still counts.

You are halfway through a sentence in a report when your phone rings. The school. Your child has a temperature and needs collecting. You close the laptop with the cursor still blinking after the word because.

Nine days later you open the file. You read the last paragraph twice. Because what? The second figure looks wrong, and you have a vague memory of knowing why. Someone was supposed to send you a number. Did they? You scroll up, then down, then check your email, and forty minutes later you have not written a word.

The report would have taken twenty minutes to finish. Getting back into it is what took the afternoon.

Two people, one name

Every time you stop something, two people are involved. One is leaving. The other comes back later, maybe tomorrow, maybe in three weeks. They share a name and very little information.

The person leaving knows exactly where things stand. The draft is half done, the figure is wrong because finance changed a number, the laundry is still wet in the machine. The person returning knows none of it. They know only that something is unfinished, and that opening it means working out what was going on.

You cannot stop the phone ringing. Interruptions will keep coming. What you can change is how much the person coming back has to rebuild.

Three lines

At the moment you stop, write three lines.

Current. What is true right now, in one or two plain facts. Sections one and two drafted. Figure 2 uses the old number, waiting on finance.

Next. One visible action. A verb and an object, ideally the real file, person or place. Keep going is a direction, not an action. Paste the new number from finance into figure 2 is an action.

Check. When you will look again. A day, a time or an event. Nine tomorrow, before email.

That is the note. It takes about a minute while the facts are still in your head. On the day of the phone call, it could even be one line typed as you stand up: waiting on finance for figure 2, finish the because sentence.

Weak notes and strong notes

A weak note scolds. Finish this tomorrow, no excuses!! It has a demand and no information, so the returning person still rebuilds everything and gets told off as well.

A strong note removes the rebuilding. Current: the draft states the problem and the recommendation. Next: check figure 2 against the source file. Check: nine tomorrow. The person coming back reads three lines and does one thing.

If your note keeps growing into a paragraph, the Next line is not sharp enough yet. Narrow it until it is one move.

Put it where you will land

A note you cannot find costs as much as no note. Choose one place and use it every time: the first line of the document, a sticky note on the laptop lid, the lock screen. Call it the restart marker. It is wherever your eyes go first on the way back in.

A notebook you never reopen does not count. Part of you knows that is where things go to disappear, so your head keeps holding the details anyway, just in case. The marker is what lets your head put them down.

When you did not get to leave a note

Sometimes the phone wins and there is no note. The file has been sitting for a week and you open it cold.

The pull is to rebuild everything: reread the history, tidy the folder, re-plan the project. Try something smaller. Find the most recent version you can trust. Write a fresh Current, Next, Check at the top of it, from what you can see now. Skip the earlier history unless the next action actually depends on it. Getting your bearings back is the whole job for today; reorganising can wait for a clearer day.

Try it cold, once

Here is a small experiment. On a day when nothing urgent depends on it, stop one piece of work on purpose, write the three lines, and close it. Come back the next morning using only the note. Then ask yourself four questions:

1. Could you tell what was true?
2. Was the next step obvious?
3. What was missing?
4. What would you add next time?

Do it once, not as a ritual. The answers will tell you more about your own notes than any advice can.

Where the idea comes from

The Check line borrows from research on implementation intentions, plans linked to a specific cue such as at nine tomorrow, I will open the report. A review by Peter Gollwitzer found these simple if-then plans helped people act on their goals (S5), and a lab study found they helped people remember to carry out a future action when their attention was busy elsewhere (S6). Neither study tested a note like this one, or tested it in adults with ADHD. Current, Next, Check is a practical tool from my book, When You Lose Track, and the fair test is your own: does coming back get quicker?

If you want a simple form for it, the Current, Next, Check tool does exactly this and nothing more.

Then go back to the report with the cursor blinking after because. With a note on top, the person who opens it nine days later reads one line, waits for nothing, and finishes the sentence.

Next time: the message from a friend you meant to answer properly, and why it gets harder to reply each day it waits.
