What's really killing your focus

Hey Everyone,

More often than not, we have less free time on our calendar than we appear to have.

And the problem is typically linked to those short 30-minute-or-less gaps between meetings.

Why free time isn't free

Look at a typical work day – 9 am call, a 30-minute gap, a 10 am review, another 30-minute gap, and then an 11:30 check-in.

While the two 30-minute gaps imply 60 free minutes in the above example, these short gaps tend to fill with lower-leverage work like email, Slack, or whatever is open on your browser.

Here's how to engineer your calendar for higher-leverage work.

What to look for on your calendar

Open your calendar for this week and count every 30-minute or shorter gap between meetings. Think honestly about what you do in those windows.

Just 2-3 of those on a typical day can damage your productivity more than the number of meetings you have.

4 calendar fixes for more focus

Cluster your meetings into defined windows: Move calls and reviews into a morning or afternoon block and keep the rest of the day clear. Atlassian, which has studied its own team focus data closely, recommends 90-minute blocks at minimum and suggests focus time should make up 30 to 40 percent of the week.

Close or extend your short gaps: When you see a 30-minute window between two meetings, either move one to close the gap entirely or push enough space between them to create a more usable 60-minute block.

Switch your meeting defaults to 25 and 50 minutes: Most gaps exist because meetings default to 30 and 60-minute slots. Both Outlook and Google Calendar let you change this in settings. Shorter defaults create a natural buffer after every call and reduce fragmentation across the whole day.

Protect one full morning per week: Pick a day and keep the first 3 hours meeting-free. It takes a few weeks for your team to adjust their scheduling habits around it, but once the pattern is established, you'll feel the difference in the quality of your thinking on those mornings compared to the rest.

Try this today

Look at tomorrow's calendar and find every gap of 30 minutes or less. For each one, either close it by moving a meeting or extend it into a real working block by shifting something else.

You don't need to restructure the whole week yet – one day with fewer fragments will show you quickly whether this is worth taking further.
