A routine is not this week's plan
The words get used interchangeably, and the blur costs people their system. A weekly routine is the repeating layer of the week: the anchors that sit in the same place every week, whatever that week turns out to hold. This week's plan is a different object entirely: the one-off arrangement of this particular week, with its particular deadline and houseguests and weather, laid out inside those anchors. Planning your week is a job you do every week. Building the routine is a design job you do once, then revisit a few times a year.
Even the ritual of planning belongs to the routine rather than the plan: the weekly reset is itself an anchor, usually somewhere around Sunday, and this week's plan is what comes out of it. Keep the two objects separate and each does its job well: the routine quietly holds, the plan honestly changes. Ask one object to do both jobs and you get the laminated ideal week that fits no week you have ever actually had.
