Deep Focus

Use when — you end every day busy, behind, and unable to say what you actually did.

Interruptions steal less time than you think — you speed up to compensate and pay in stress and shallower thinking instead. And about half of them, you start yourself. The fix isn’t a better calendar; it’s a defended attention supply.

✓Done when — One day’s interruptions tallied, split into “them” vs “me” — with the “me” column targeted for tomorrow.

Gloria Mark et al., “The Cost of Interrupted Work” (CHI 2008) — faster, but more stress; ~half are self-interruptions.

Use when — the phone is face-down “so it doesn’t distract you” — and pulls your eye anyway.

A visible phone is an invitation your willpower must decline hundreds of times a day — and willpower loses. Remove the cue and you never spend the willpower at all.

✓Done when — Your next focus block ran with the phone physically in another room — not pocket, not desk.

James Clear, “Atomic Habits” (2018) — make the cue invisible; environment beats willpower.

Use when — “got a sec?” has eaten every morning this week.

An undefended block gets booked, pinged and shoulder-tapped. A friendly, specific boundary does most of the defending for you — say it before you need it.

✓Done when — Next block announced with an end time and an emergency channel; zero guilt.

Cal Newport, “Deep Work” (2016); Paul Graham, “Maker’s Schedule, Manager’s Schedule” (2009).

Use when — twenty small items got done and the one that mattered didn’t.

A long list scatters attention; a single Highlight aims it. Choose the one thing that would make today feel worthwhile — then give it your best hours, not your leftovers.

1. Each morning, name one Highlight: meaningful, doable in 60–90 minutes.
2. Ask: what would make today feel like a win?
3. Block the time before reactive work starts.
4. Do it first. Everything else is bonus.

✓Done when — Tomorrow’s Highlight is one sentence and a 90-minute block on the calendar.
