The two-minute rule: how to use it without losing your focus

Allen’s rule: finish it now

The original comes from David Allen, who wrote Getting Things Done: "Anything you can do in less than two minutes, if you need to do it at all then do it right then."

His reasoning is simple. If you put a tiny task on a list, you'll spend more than two minutes reading it, thinking about it and coming back to it later. Just do it.

Think of the email that needs a one-line yes, the invoice that needs approving, the meeting that needs moving. Each one is faster to finish than to track.

For clearing an inbox or a pile of small requests, it works beautifully. The pile shrinks, and nothing small sits around nagging you.

Clear’s rule: start with two minutes

James Clear, who wrote Atomic Habits, uses the same name for a different idea: "When you start a new habit, it should take less than two minutes to do."

"Read before bed" becomes "read one page." "Study for class" becomes "open my notes." The point isn't to finish anything. It's to make starting so small that there's nothing to resist.

At work, that looks like: "write the proposal" becomes "open the doc and write the heading." "Call the supplier" becomes "find their number and dial." "Plan the quarter" becomes "write three goals on a sticky note."

None of those finish the job. They get you past the moment where the job feels too big to begin, which is usually where the day goes wrong. Once you've started, carrying on is much easier than starting was.

When Allen’s rule goes wrong

The trouble starts when you use Allen's rule in the middle of focused work.

Every "quick" reply is a switch. Sophie Leroy, who studies attention at work, found that when people move on from an unfinished task, part of their attention stays stuck on it. She calls it attention residue. So the 30-second Slack reply doesn't cost 30 seconds. It costs the next ten minutes of your report, which you now come back to with half your mind still in Slack. More in context switching.

That's the opening scene: thirty sensible two-minute decisions that add up to a lost hour.

Allen's rule was never meant to run all day. It's a tool for processing time, when your job is to get through the pile. During focus time, your job is one thing.

How to use both today

During focus blocks, list, don't do. Keep a scrap of paper next to you. When a two-minute task comes up, write it down and keep going.

Clear the list twice a day. Late morning and late afternoon, take that list and your inbox and apply Allen's rule hard: if it's under two minutes, do it now.

Use Clear's rule on the task you're avoiding. Shrink it to a two-minute start: open the file, write the first line, send the first message. If it still won't start, read no motivation to work.

Hide the badges during focus blocks. Close the email tab and pause Slack notifications, so new two-minute tasks can't find you until list time.

Watch for fake two-minute tasks. If a "quick" one is still going after ten minutes, stop and give it a proper slot in your calendar.

So, what's the two-minute version of the task you've been avoiding all week?
