Here is a confession that is embarrassing to type: before this experiment, I genuinely thought I was good at multitasking. I was the person with seventeen browser tabs, a half-written email, a phone call on speaker, and a simmering pot on the stove, convinced I was getting more done than anyone else in the house. Spoiler: I was not.
A friend sent me a study about task-switching — the kind where scientists measure what actually happens in your brain when you try to do two things at once. The short version: you do not do two things at once. You switch rapidly between them, and each switch costs you a little bit of focus that you never get back. The researchers called these “switch costs.” I called them Tuesday.
So I decided to try something that felt radical. For one month, I would do one thing at a time. One thing. Not two. Not three. Just the thing in front of me, until either I finished or I chose to stop. No email while on a call. No scrolling while eating. No half-listening to my daughter while mentally drafting a shopping list.
Week One: Withdrawal
The first week was physically uncomfortable. I kept catching myself reaching for my phone mid-task without any conscious intention. My hand just went there, like a dog returning to a spot it had peed on. The urge to add a second activity to any moment of singular focus was so strong I started keeping a tally. By Wednesday, I had caught myself attempting to multitask forty-three times. In three days.
Cooking without a podcast felt wrong. Folding laundry without a show in the background felt like punishment. But I stuck with it, mostly out of stubbornness, and by Friday something strange happened. I finished cooking dinner twelve minutes faster than usual. I had no idea where the extra time came from until I realized I had simply not stopped four times to answer texts or skip a song.
Week Two: The Time Glitch
This is the week where the experiment started to feel almost magical. Tasks that usually took me an hour were taking forty minutes. Not because I was working faster. Because I was not constantly stopping and restarting. The switch costs were gone, and without them, my actual output speed was significantly higher than I had ever given myself credit for.
The strangest part: my days started feeling longer. Not in a bad way. In the way where you look at the clock and realize it is only 2 PM and you have already done the thing you used to still be doing at 4. The reclaimed time was not dramatic — maybe an hour and a half across the day — but an hour and a half of extra margin when you have young children is basically a fortune.
Week Three: The Listening
Somewhere around the third week, I noticed I was having better conversations. With my partner. With my kids. Even with the cashier at the grocery store. When I was not running a parallel mental thread during. (Much like when I wrote about tracked every minute, this experiment gave me data I could not ignore.) every interaction — what should we have for dinner, did I reply to that email, is tomorrow the dentist — I was actually hearing what people said. And responding to it, instead of responding to my best guess at what they probably said while I was half-present.
My daughter, without prompting, said one evening: “Mama, you are listening more.” She was right. I was. And the fact that a four-year-old noticed tells you how bad the half-listening had been before.
Week Four: The Hard Truth
By the end of the month, I had to admit something I had been avoiding. Multitasking was never about productivity. It was about anxiety. I kept my brain occupied with multiple inputs because silence — real, empty, unstimulated silence — made me nervous. What would I think about if I just sat there folding laundry with nothing in my ears? What feeling would surface if I cooked dinner without a distraction?
That was the real discovery. The switch costs were not just cognitive. They were emotional. I was drowning out my own thoughts with a constant stream of secondary inputs, and calling it efficiency.
Where I Landed
I am not a single-tasking monk now. I still listen to podcasts when I run. I still sometimes eat lunch while reading. But I am far more aware of when I am adding a second task and why. Most of the time, I do not need it. I just want it, because quiet is uncomfortable and focus is hard.
But the uncomfortable thing and the hard thing are usually the thing worth doing. And doing one thing at a time, it turns out, is one of those.
