An anchor that held all night can drag when the wind shifts. Recheck your plan when things change.

Something that worked is evidence about the conditions it worked in, not a guarantee. Boats drag anchor when the wind swings, not because the anchor got worse overnight. Study routines, training schedules and arrangements with friends all hold until something underneath them moves. The trap is that holding feels like proof, so nobody looks again.

Pick whatever changed for you recently: a new class, a new shift pattern, an injury, a friend group that shifted. Check whether the plan built before that still makes sense. Five minutes when conditions move beats discovering in December that you have been drifting since September.
