Multitasking Is a Myth: Why One Task at a Time Works

I used to think I was productive because I was always doing something.

An email opens on one screen. Slack on another. ChatGPT helping with research. A meeting playing in the background. My phone buzzes every few minutes.

By lunchtime, I felt busy. By the end of the day. I could not point to one meaningful task I have actually finished.

That’s the illusion of multitasking. It makes us feel productive while quietly stealing the focus needed to do our best work.

Is multitasking really a myth?

For mentally demanding work, yes what we call multitasking is usually task switching.

Your brain is not writing an email while listening to a meeting and planning tomorrow’s presentation at the same time. It’s rapidly shifting between them.

Every switch comes with a hidden cost. You lose your train of thought, spend time remembering where you left off and need extra mental effort to get back into the task.

Research has consistently found that people who frequently multitask are more easily distracted and perform worse on tasks that require sustained attention than those who focus on one thing at a time.

The hidden cost of switching tasks

Imagine you are writing an important report when a slack notification appears. You reply because it only takes a few seconds.

When you return to your report, you suddenly wonder, “Where was I” and “What was I about to write?”.

Researchers call this attention residue. Part of your attention stays with the previous task even after you have moved on. The more often you switch, the harder it becomes to fully concentrate on what you are doing now.

This is why a day filled with interruptions feels exhausting, even if none of the individual tasks were especially difficult.

Why multitasking feels productive

If multitasking hurts productivity, why do we keep doing it?

Because it feels rewarding. Every notification, message or completed reply creates a small sense of progress.

Clearing emails and responding quickly gives us the impression that we are getting things done. The problem is that being busy is not the same as making progress.

You can finish the day with an empty inbox while the project that actually matters barely moves forward.

Activity is easy to measure. Meaningful work isn’t.

Not all multitasking is bad

This is where the conversation needs balance. Some combinations work well because only one task requires real mental effort.

Listening to a podcast while walking. Brainstorming during your commute. Folding laundry while thinking through an idea.

These combine an automatic physical activity with a thinking task. What does not work is combining two tasks that both require concentration.

Writing while answering emails. Reviewing a proposal during a meeting.

Planning next week’s strategy while constantly checking slack. Those activities compete for the same limited attention.

Modern work makes focus harder

Multitasking isn’t just a habit anymore. It’s built into the way many of us work.

Emails arrive while we are writing. Team chats interrupt deep work. Calendar reminders appear in the middle of focused thinking.

AI tools make it easy to ask one more question before returning to the task in front of us.

None of these interruptions seem significant on their own.

Together, they create a workday where our attention is constantly fragmented.

Instead of deciding what deserves our focus, we react to whatever appears next.

The people who focus best protect their attention

Highly productive people aren’t necessarily more disciplined. They simply create fewer opportunities for distraction.

They batch emails instead of checking them every few minutes. They silence notifications while working on important projects.

They finish one meaningful task before starting another. They also avoid carrying every reminder in their head.

I prefer keeping ideas, follow ups and tasks in one trusted place. Tools like mysamantha.ai help capture those loose ends so they stop competing for attention while I am trying to focus.

The goal is not a perfect organization. It’s giving your brain fewer things to juggle.

One question changed how I work

I stopped asking, “How much can I finish today?”. Instead I started asking, “What deserves my full attention right now?”.

That simple shift changed everything. I finished more meaningful work. The meeting became more productive because I was actually listening.

Writing became easier because I was not rebuilding my thoughts every few minutes.

Even conversations outside work improved because I was finally present instead of mentally jumping to the next task.

People notice when you give them your full attention. More importantly, you notice it too.

Your attention is your greatest advantage

We spend so much time managing our schedules that we forget to manage the thing that actually drives great work.

Our attention. You can’t create more hours in the day, but you can decide where your focus goes.

That’s why multitasking is a myth. It promises more productivity but usually delivers more distractions, more mental fatigue, and lower quality work.

If notifications, unfinished tasks, and scattered ideas constantly pull your mind in different directions, no productivity system will completely solve the problem.

Sometimes the biggest improvement comes from reducing the number of things competing for your focus.

Keeping your tasks and reminders organized in one place, whether that’s through better personal habits or a workspace like mysamantha.ai, makes it easier to stay with one important task long enough to do it well.

Real productivity is not about doing more things at once. It’s about giving the right thing your complete attention until it’s finished.
