Capacity Inventory
This is how you stop building a to do list that ruins your day. Plan to your actual battery level, not your fantasy self on a perfect morning.
Low capacity is not a moral failure, it is a data point. This page helps you measure what you have, score it, and prune the list before the shame spiral starts.
Adjust the list to fit the energy, not the energy to fit the list. Pushing harder is not “discipline” if it costs you two days of recovery.
Capacity is variable. Worth is constant.
Capacity is not just time. It is executive function, pain load, sensory load, and emotional load. Two hours on a good day and two hours on a bad day are not the same resource.
Use it before you build a list, before you accept new commitments, and any time you notice, “I am about to overpromise and hate myself later.”
Less than 6 hours, broken sleep, or waking up already tired, counts.
Pain up today, meds wearing off, blood sugar chaos, hormone shifts, flare days, all of it counts.
Loud environments, bright light, scratchy clothes, clutter, and interruptions burn battery fast.
Hunger and dehydration create fake emergencies. Your brain reads it as threat.
Reality check: If your brain feels “slow,” check whether it is overloaded, not broken. Capacity problems often look like motivation problems from the outside.
Best for: scary task first, deep work, learning, high executive function tasks.
Rules: go fast, protect focus, do not waste the spike on low-value busywork.
Risk: overcommitting because it feels good, and then crashing tomorrow.
Strategy: use the energy while it is here, then stop.
Best for: routine tasks, admin, cleaning, email, one big thing maximum.
Rules: finish what you start, do not stack three hard tasks “just in case.”
Risk: trying to sprint on a maintenance battery and burning out by 2 PM.
Strategy: maintain baseline, do not start new projects.
Best for: food, meds, hygiene, minimum viable work, and one true fire only.
Rules: cut the list by 70 percent, no big decisions, no “catch up” fantasies.
Risk: pushing anyway, and paying for it with a multi-day collapse.
Strategy: protect tomorrow, because tomorrow is built from today’s recovery.
Practical scoring tip: If you are unsure, assume the lower zone. You can always add one more task later, but you cannot undo a crash.
Pick one real priority and two maintenance tasks. Everything else becomes “later.”
Green is not permission to schedule your whole life in one day.
Your worth is constant. Your capacity is variable.
A low-capacity day does not mean you are a low-value person.

Mechanisms behind “capacity,” fatigue, and planning

Sleep restriction reliably impairs attention, working memory, and decision-making. The “subtract capacity after a bad night” rule matches how cognitive performance drops under sleep debt.
Neurobehavioral functions and effects of sleep loss, Lim and Dinges (2010), LancetRepeated decisions increase mental fatigue and reduce self-control and persistence. “Use defaults, reduce choices” is a practical way to lower decision load before planning.
Ego depletion and self-control, Baumeister et al. (2003), Journal of Experimental Social PsychologyAllostatic load describes the wear and tear of chronic stress on body systems. The “survival day” is a recovery strategy, not laziness, when stress load is high.
Protective and damaging effects of stress mediators, McEwen (1998), The New England Journal of MedicineWhen task demands exceed working memory capacity, performance collapses. Capacity Inventory reduces overload by forcing a smaller plan that fits the system.
