Turn the task list into a realistic plan for one day.
Date, working window, fixed events, breaks, transitions, energy, and shutdown:
[day]
Tasks, deadlines, estimates, dependencies, consequences, and minimum useful results:
[tasks]
Priorities, interruption risk, focus limits, personal needs, and movable work:
[rules]
Calculate usable capacity after fixed events, breaks, transitions, and an explicit interruption buffer. Do not schedule more estimated work than fits or silently shorten tasks. Select must-do work using deadlines, consequence, dependency, and value; distinguish appointments, focused work, shallow work, and optional tasks. Return a time-blocked schedule with start/end, task, intended result, and setup; a capacity reconciliation; tasks deliberately deferred with reason and next review; a small overflow rule for delays; and a shutdown checklist. Preserve meals, care, health, and stated boundaries. Mark missing estimates rather than inventing them.

From input to outcome
A worked example
See how concrete context turns this recipe into a usable result
Actual input
Available day and energy
Tuesday 09:00–17:30 from home. Fixed: team call 10:00–10:30, school pickup 15:00–15:40 including travel, lunch 12:30–13:00. Best focus before noon; maximum 90-minute focus blocks. Stop at 17:30.
Task list
Submit grant budget by 12:00, estimate 75 min, needs 10-min final check, missing two supplier amounts but placeholders are allowed. Review Mia's proposal by Wednesday, 50 min. Answer 14 routine emails, estimate 35 min. Prepare Thursday workshop slides, 120 min, first useful result is approved outline, 35 min. Book dentist, 10 min. Reconcile expenses by Friday, 60 min. Unexpected client question likely, reserve 30 min.
Planning rules
Grant is highest consequence. Proposal review should happen today if capacity allows. Keep lunch and pickup. No work after 17:30. Use email in one batch; include 15-minute transition after pickup.
Example output
Usable window is 510 minutes. Fixed call, pickup, lunch, post-pickup transition, and client buffer use 145 minutes, leaving 365 task minutes. Listed work totals 395 minutes if the workshop is reduced to its stated 35-minute minimum; therefore 30 minutes must be deferred.
09:00–09:50 grant budget draft and insert labeled supplier placeholders; 09:50–10:00 note missing amounts. 10:00–10:30 team call. 10:30–10:55 finish budget; 10:55–11:05 final check; 11:05–11:15 submit and save confirmation. 11:15–12:05 review Mia's proposal. 12:05–12:30 email batch part 1. 12:30–13:00 lunch. 13:00–13:35 workshop outline; output: reviewable structure, not finished slides. 13:35–14:05 reserved client buffer. 14:05–14:15 book dentist. 14:15–14:25 finish email batch. 14:25–15:00 optional start on expenses. 15:00–15:40 pickup; 15:40–15:55 transition. 15:55–16:20 finish remaining expense work up to the 60-minute total. 16:20–17:10 flex for client question or proposal/grant overrun. 17:10–17:30 shutdown and Wednesday plan.
Defer full slide production to Wednesday after outline review. If the 50-minute flex is consumed, defer expenses—not lunch, pickup, grant, or proposal—and review Wednesday morning.
Why this works
1
Capacity reconciliation makes overcommitment visible before the day begins.
2
Deliberate deferral preserves trust in the plan better than hiding extra work outside the calendar.
Check the result
Do scheduled task estimates plus buffers fit the actual available minutes?
Are fixed needs, dependencies, and shutdown boundaries preserved?
Does every deferred task have a reason and next review point?
