How to protect your focus when everything competes for it

I once tracked how many times I got interrupted during a single morning. By 11am, the count was 14. Slack messages, a colleague walking over, email notifications, a phone buzzing. Fourteen interruptions before lunch. And I thought I was having a productive morning.

The thing about interruptions is they don't just cost you the time of the interruption itself. Research shows it takes about 23 minutes to fully regain focus after being pulled away from a task. Fourteen interruptions times 23 minutes is over five hours of lost focus. In a morning. That number changed how I think about protecting my time.

Shallow work eats your calendar

Cal Newport draws a sharp line in Deep Work between two types of effort. Shallow work is the constant stream of small tasks: replying to emails, answering quick questions, attending status meetings, clearing notifications. It feels productive. It keeps you busy. But it rarely moves anything meaningful forward.

Deep work is the opposite: sustained, uninterrupted focus on a single high-value task. Writing that proposal. Building that strategy. Solving the hard problem you've been avoiding. This is the work that actually advances your goals, and it requires stretches of 60-90 minutes where nobody and nothing breaks your concentration.

As Newport puts it: "It's not about being talented. It's what you produce that counts, and it's your responsibility to protect your focus to get great work done."

The problem is that nobody protects your focus for you. If you don't schedule deep work, shallow work fills every available slot. And at the end of the day, you've been busy for eight hours but can't point to a single thing you've finished.

The morning advantage

I do deep work first thing in the morning. Before email. Before Slack. Before anything. 90 minutes on the most important task of the day.

Why mornings? Willpower depletes as the day goes on. Every decision you make, every small task you handle, takes a slice of your cognitive energy. By the afternoon, you're running on fumes. But at 8am, you're fresh. If you spend that freshness on email, you've burned your best hours on someone else's priorities.

I set my calendar to "focus time" in Google Calendar during these blocks. It automatically sets my chat to Do Not Disturb and declines meeting invitations. My phone goes face-down in a drawer. Not on silent on the desk. In a drawer. Because research shows that even a phone you can see (even turned off) is distracting enough to reduce cognitive performance.

External distractions: the ones you can control

Most external distractions come from notifications. And most notifications are completely unnecessary. When was the last time you reviewed which apps are allowed to send you notifications? Go into your phone settings and look. You'll find apps you downloaded months ago that are still pinging you. Turn them off. Keep your bank, your calendar, and your messaging app. Delete the rest.

During deep work, I go further. Do Not Disturb on my phone, my laptop, and inside Google Chat. I use a browser extension called Freedom that blocks distracting websites during focus hours. News sites, social media, anything that pulls me out of the task. If it sounds extreme, try it for one week. The clarity is remarkable.

A football player doesn't check their phone between plays. Your deep work block deserves the same respect.

Internal distractions: the harder problem

External distractions are relatively easy to fix. Turn off the notification. Close the app. Internal distractions are sneakier. That nagging thought about an email you need to send. The worry about a deadline next week. The sudden urge to Google something completely unrelated.

When this happens during a deep work block, I write the thought down on a notepad next to me and go straight back to the task. I don't open a new tab. I don't switch to my inbox "just for a second." I capture the thought (see the article on capturing) and return to the work. The notepad becomes my parking lot for distractions.

The other internal challenge is saying no. If you're a team player (and most of us want to be), someone walking up and asking for help feels impossible to refuse. Here's a script that works: "I'm happy to help. Here are the five things on my plate this week. Can you help me figure out where this sits in the priority list?" You're not saying no. You're asking for help prioritising. And nine times out of ten, the person realises their request can wait.

The meeting trap

Scattered meetings are the silent killer of deep work. If your calendar has meetings at 9am, 11am, 1pm, and 3pm, you technically have gaps between them. But those 60-minute windows are too short for deep work and too long to feel like a break. The result is four hours of shallow work squeezed between meetings.

The fix: cluster your meetings. Move them as close together as possible. If you have a one-on-one with a colleague, ask to move it next to another meeting you already have. This creates longer, unbroken blocks of time. Even moving two meetings to be back-to-back can free up a full deep work block.

Focus isn't something you find. It's something you protect. Turn off the notifications. Schedule the deep work block. Put the phone in a drawer. Cluster your meetings. These are small changes, but they compound. One deep work block per day, five days a week, is over 30 hours per month of focused, high-quality work that most people never get to.

Start tomorrow morning. 90 minutes. One task. Phone in the drawer. See what happens.
