Make a weekly plan using only these available focus blocks:
Monday 09:00–09:45; Tuesday 09:00–09:45; Wednesday 09:00–10:00; Thursday 09:00–09:45; Friday 09:00–09:45 and 14:00–15:00.
Keep Friday 14:00–15:00 completely empty as a buffer.
Tasks: presentation draft, 90 minutes, due Thursday noon, can split; expense report, 60 minutes, due Wednesday noon, cannot split; reading notes, 45 minutes, due Friday noon; cupboard sorting, 75 minutes, no deadline, can split.
Choose deadline-bound work first. Use spare time for cupboard sorting. Never double-book a block or schedule outside these times. Show a day-by-day table, scheduled minutes, buffer minutes and unfinished work. Do not pretend all work fits.
