Deep work — the kind of focused effort that produces your best thinking — needs long, uninterrupted blocks, but most work calendars are built around the opposite: short, frequent interruptions in the form of meetings.
Find your natural meeting-free zones first
Before trying to force new gaps into a busy calendar, look at when meetings already tend not to happen — often early mornings or the last hour of the day. Claim these existing gaps for deep work before adding anything new, since they're the path of least resistance.
Batch meetings instead of spreading them out
A meeting at 10am, another at 1pm, and another at 3:30pm doesn't leave three free stretches — it leaves three stretches too short and too interrupted to actually use for focused work. Where you have any control over your own schedule, push meetings to cluster on fewer days or into a single block, freeing up full uninterrupted stretches elsewhere.
Block deep work like it's a meeting with yourself
A task written on a to-do list gets deprioritized the moment a meeting request comes in. A block on the calendar, labeled and defended the same way you'd defend an actual meeting, is far harder to casually overwrite — both by other people and by yourself.
Protect the first deep work block of the week especially
The Monday morning slot (or whatever your week's first deep work block is) tends to get sacrificed first when a "quick" meeting request comes in, because the week feels like it hasn't started yet. Treat it as non-negotiable — losing it sets a precedent for the rest of the week.
Communicate the block, don't just hide behind it
If colleagues don't know a slot is protected, they'll keep booking over it. A short note on a shared calendar — "focus block, message if urgent" — usually gets respected far more often than a silently blocked slot with no explanation.
