The rule
2+ stop signs in one session → end the block early
Why stop
Diminishing returns
Hour eight ≠ hour three. Extra minutes cost tomorrow's recall.
Fatigue signals
Rereading, errors, irritability — your brain warns before collapse.
Planned rest
Breaks in your planner are tasks, not guilt.
7 stop signs
Same line three times, zero recall
Encoding stopped. Rest beats rereading.
Error rate doubled in 30 minutes
Tired practice drills mistakes into memory.
Headache, eye strain, or micro-sleeps
Walk 10 minutes — beats another chapter.
Snapping at small interruptions
Cognitive budget empty. Stop before study feels like stress.
Timers done, zero tasks completed
Busywork, not progress. Sprints need a finish line.
Past planned end time "just because"
Overtime steals tomorrow's sleep and focus.
Already dreading tomorrow's session
Burnout signal — recovery day, not another forced hour.

Your stop rule
Planned end time → Pomodoro sprints, one task each → 2+ signs, stop early → log wins → sleep. Kaizen treats rest as part of the system — ending on time is a process win, not failure.
Frequently asked questions
How many hours should a student study daily?
6–8 quality hours for most exam prep. Stop when recall drops — not when the clock says so.
Is it OK to stop studying early?
Yes. Four focused hours beat eight exhausted ones. Protect tomorrow.
Break vs stopping for the day?
5–15 min for mid-sprint fog. 30–60 min after a block crash. Full day off for burnout signs.
