Single-Task on Purpose — Beat the Myth of Multitasking
Multitasking feels productive and quietly wrecks your output. The brain can't do two focused things at once — it switches, and pays a tax each time. Learn to single-task on purpose.
The idea
Your brain can't truly do two demanding things at once. What feels like multitasking is rapid switching, and each switch has a cost — studies suggest it can cut effective productivity by up to 40% and make you more error-prone. The fix is single-tasking on purpose: pick one task, close everything else, and stay on it until a natural stopping point. This is different from blocking interruptions (that's about other people) — this is about not interrupting yourself by chasing the next tab, message, or shiny idea mid-task.
Who is this for?

Tara wrote with email, Slack, and six tabs open, "staying on top of things." A 2-hour article took all day.
She tried single-tasking: one document, everything else closed, phone in a drawer, until a section was done.
The article was finished in 90 minutes — and read better. The "staying on top of things" had been the thing slowing her down.
"I wasn't multitasking. I was interrupting myself all day and calling it work."

Do the challenge
1Pick one task and define "done for now"
Choose a single task and decide the natural stopping point — "finish this section," "clear this decision," "draft this reply." A clear finish line keeps you from drifting.
💡 Single-tasking needs a target. "Work on the report" invites wandering; "write the summary section" gives your attention a place to land and a place to stop.
2Close everything else — really
Shut the other tabs, quit the chat apps, put the phone face-down or in another room. Out of sight genuinely means out of mind. One task visible, nothing else competing.
3When the urge to switch hits, note it and stay
Mid-task you'll feel the pull to check something or chase a new idea. Jot it on a scrap pad ("check X later") and return to the task. The note frees your mind without breaking focus.
💡 Help me set up a 45-minute single-task session. My task: [task]. Ask me 2 questions to define a clear "done for now" stopping point, then give me a 3-step setup to remove distractions and a one-line rule for what to do when I feel the urge to switch.
4Finish, then switch deliberately
Take the task to your stopping point before you touch anything else. Then, on purpose, switch to the next thing or process your "check later" notes. Switching by choice is fine; switching by reflex is the tax.
Your template
SINGLE-TASK ON PURPOSE THE ONE TASK: __________________________________ "DONE FOR NOW" LOOKS LIKE: ____________________ (a clear stopping point, not "work on it") CLOSE-EVERYTHING-ELSE CHECKLIST: □ Other tabs closed □ Slack / WhatsApp / email quit □ Phone face-down or in another room □ One task visible, nothing else WHEN THE URGE TO SWITCH HITS: Write it here → "check later: ______________" …then return to the task. Don't act on it now. AFTER I HIT THE STOPPING POINT: □ Switch deliberately (my choice, not a reflex) □ Process my "check later" notes Time on task before first switch: ______ min
