Single-Tasking: Why Focus Beats Multitasking
Doing two things at once sounds efficient — but your brain pays a hidden tax every time it switches. Here's how to get that energy back.
Somewhere along the way, multitasking became a badge of honour. If you're juggling calls, emails, and a document at the same time, you must be productive — right? The research says otherwise. Every time your brain switches from one task to another, it pays a cost in time, energy, and accuracy. Cognitive scientists call it "switch cost," and it adds up faster than you'd expect.
The good news is the solution isn't complicated. Single-tasking — genuinely doing one thing at a time — lets your brain settle into a task properly, build real momentum, and produce better work with less exhaustion. You probably already know this from experience: the times you've felt most capable are usually the times you were deeply absorbed in one thing.
How to set yourself up for single-tasking
The challenge isn't understanding that single-tasking works — it's making it easy to actually do. Your environment and habits have to support it, because the pull toward checking messages or bouncing between tabs is real and constant. These steps close the exits so you can stay in the work.
Make single-tasking your default
- Choose one thing before you open anything. Before you touch your keyboard, decide what the one task is. Write it on a sticky note and put it where you can see it. This anchors your session and gives you something to return to when you drift.
- Close what you don't need right now. Every open tab and notification is a potential interruption. Close your email client, mute your phone, and shut down tabs unrelated to the current task. The goal is to make drifting inconvenient.
- Work in defined blocks of time. Give your single task a clear start and end — even 25 to 45 minutes works well. Knowing there's a boundary makes it easier to commit fully, because your brain can see the finish line.
- Keep a "parking lot" for intrusive thoughts. When a good idea or reminder pops into your head mid-task, don't switch — write it on a scrap of paper and return to your work. You won't lose the thought, and you won't lose your focus.
- Transition deliberately between tasks. When you finish one task, take 30 seconds to note where you left off before starting the next. A clean handoff between tasks reduces the mental residue that makes switching so costly.
One thing, done well, is worth more than ten things done halfway.— BetterAlong
Start small: pick one task this afternoon and protect it for 25 minutes. No tabs, no phone, just that one thing. Notice how it feels to actually finish something. That feeling is worth building on.
