Psychology says multitasking reduces productivity by up to 40%. Here’s how I finally committed to doing one thing at a time

Know that feeling when you’re juggling three different tasks, your phone’s buzzing with notifications, and you’re convinced you’re being super productive? Yeah, I lived in that state for years, and spoiler alert: I wasn’t actually getting much done.

The truth is, I used to be a multitasking junkie. I’d write an article while responding to emails, take calls during lunch, and plan tomorrow’s content while trying to have a conversation with my partner. I wore my ability to juggle multiple things like a badge of honor, thinking it made me more efficient, more capable, more… everything.

Then I stumbled across a post from the American Psychological Association which told me that multitasking can reduce productivity by up to 40%. Forty percent. That’s nearly half of your potential output just evaporating into thin air because you’re trying to do too much at once.

At first, I didn’t want to believe it. But when I looked at my own life, the evidence was right there. Projects took twice as long as they should. I made stupid mistakes that required hours to fix.

And worst of all, I constantly felt scattered, like my brain was a browser with 47 tabs open and a spinning wheel of death.

The wake-up call that changed everything

The turning point came during a particularly chaotic week while building Hack Spirit. I was writing an important piece, answering Slack messages, and half-listening to a podcast about productivity (the irony wasn’t lost on me later).

Six hours later, I’d written maybe 500 mediocre words, sent a bunch of half-baked responses, and couldn’t remember a single thing from that podcast.

That’s when it hit me: I wasn’t being productive. I was just being busy.

Our brains aren’t actually capable of focusing on multiple complex tasks simultaneously. What we call multitasking is really just rapid task-switching, and every switch comes with a cognitive cost. It’s like constantly changing gears in a car – you lose momentum every single time.

Learning from ancient wisdom

As someone who’s spent years studying Eastern philosophy and even wrote a book called Hidden Secrets of Buddhism: How To Live With Maximum Impact and Minimum Ego, you’d think I would’ve figured this out sooner.

 There’s a Zen proverb that goes, “When walking, walk. When eating, eat.” Simple, right? But somehow, in our modern world, we’ve convinced ourselves that when walking, we should also be checking email, planning dinner, and listening to a podcast at 1.5x speed.

The concept of single-pointed concentration isn’t just about meditation. It’s about bringing that same quality of undivided attention to everything you do. Whether you’re writing code, having a conversation, or playing with your kids, being fully present transforms both the quality of your work and your experience of it.

Starting with the hardest part

The first step in my single-tasking journey? Admitting that I had a problem.

Throughout my 20s, I battled an overactive mind, constantly bouncing between worrying about the future and regretting the past. Multitasking felt natural because my brain was already doing it anyway.

But here’s what I learned: single-tasking isn’t just about productivity. It’s about mental health. When you focus on one thing, your anxiety has nowhere to hide. You can’t distract yourself from difficult emotions by jumping to the next task. You have to sit with whatever you’re doing, fully and completely.

It was uncomfortable at first. Really uncomfortable. My brain would rebel, desperately seeking the dopamine hit of switching tasks or checking notifications. But gradually, something shifted.

The practical strategies that actually work

So how do you actually make this happen in a world designed for distraction?

First, I started time-blocking religiously. Not just vague blocks like “morning: work on article,” but specific, single-task blocks. 9-10 AM: Write introduction. 10-11 AM: Research statistics. No overlap, no exceptions.

Phone management became crucial. I don’t just put it on silent; I put it in another room. The physical barrier makes a huge difference. Out of sight really does mean out of mind.

I also discovered the power of declaring my intentions. Before starting any task, I literally say out loud what I’m about to do. “I’m going to spend the next hour writing.” It sounds weird, but it works. It’s like making a contract with yourself.

The Pomodoro Technique became my best friend, but with a twist. Instead of the traditional 25-minute blocks, I adapted it based on the task. Writing gets 45-minute blocks. Email gets 15. The key is matching the time to the cognitive demand of the task.

What single-tasking really looks like

These days, my daily writing practice looks completely different. I sit down, close everything except my writing app, and write. That’s it. No extra tabs open “just in case.” No quick email checks between paragraphs. Just me and the words.

Recently becoming a father has only reinforced this approach. When I’m with my daughter, I’m fully with her. Not thinking about work, not mentally drafting articles, just present. Turns out, babies are excellent teachers of single-tasking. They demand your complete attention, and they know when you’re faking it!

The results speak for themselves. I write more in two focused hours than I used to produce in an entire distracted day. Dare I say the quality is better too. When you give something your full attention, you catch nuances you’d miss otherwise. You make connections that only emerge from deep focus.

The unexpected benefits

What surprised me most wasn’t the productivity boost, though that 40% recovery is very real. It was everything else.

My anxiety decreased significantly. When you’re not constantly jumping between tasks, your nervous system gets a chance to actually calm down. You’re not in perpetual fight-or-flight mode.

Creativity flourished. Boredom, which I used to fear, became a gateway to new ideas. When you’re not constantly stimulated, your mind wanders in productive ways.

Relationships improved. Turns out, people can tell when you’re only half-listening. Single-tasking made me a better partner, brother, and now father.

Even simple pleasures became more enjoyable. Coffee tastes better when you’re not simultaneously scrolling through Twitter. A walk is more refreshing when you’re actually noticing your surroundings.

Final words

Look, I get it. The world won’t stop demanding your attention in seventeen different directions. Your boss isn’t going to suddenly say, “Take your time, focus on one thing.” The notifications won’t stop coming.

But you have more control than you think. Every time you choose to focus on one task, you’re reclaiming a piece of your cognitive territory. You’re saying no to the myth that busy equals productive.

Start small. Pick one task tomorrow and give it your complete, undivided attention for just 30 minutes. No phone, no tabs, no mental multitasking. Just you and that one thing.

It might feel weird. Your brain might protest. You might feel like you’re falling behind. But trust the process. Trust the science. And most importantly, trust yourself.

Because once you experience the clarity, calm, and effectiveness of true single-tasking, you’ll wonder why you ever tried to do it any other way.
