Why Plan by the Week
A month is the right unit for seeing commitments; a week is the right unit for doing the work. Seven days is short enough that you can hold the whole thing in your head, and long enough to make real progress on something that matters. It is also the natural rhythm of most jobs, schools and households.
Plan the week before it starts
Twenty minutes on a Sunday evening — or Friday afternoon — is worth more than an hour of firefighting on Wednesday. Look at the fixed commitments first, then decide where the important-but-not-urgent work goes.
Give every day one main thing
A day with five priorities has none. Write one clear focus per day in the boxes above and treat everything else as secondary. Five completed priorities beats twenty half-finished tasks at the end of the week.
Protect one lighter day
Something always runs over. Deliberately leaving one day less full than the others gives the week somewhere to absorb the overflow instead of pushing it into the weekend.
