Planning with fluctuating energy: a gentler way through the day
If your energy changes day to day, a planner that assumes a flat, identical day sets you up to fail. Here’s a gentler model — and how Little Hollow and Pip put it into practice.
Why flat-capacity planners fail you
Most productivity tools assume a constant daily capacity: the same energy, the same focus, the same twenty-four hours to spend. For anyone living with MS, long COVID, chronic fatigue, migraine, chronic pain, or burnout, that assumption quietly breaks. Good days and bad days aren’t a scheduling failure — they’re the actual terrain. A to-do list built for your best day becomes a daily reminder of everything you didn’t manage, which is exactly the opposite of what a planner should do.
Spoon theory: a budget that changes daily
The idea that resonates most in chronic-illness communities is spoon theory: you start each day with a limited, fluctuating number of “spoons,” and every task spends some. On a low-spoon day, a shower and a phone call might be the whole budget. Clinicians describe this kind of pacing as a real strategy for managing energy-limiting conditions (see the Cleveland Clinic health library). The key insight: the budget is not fixed, so your plan shouldn’t be either.
Capacity-based planning, in practice
Capacity-based planning flips the default. Instead of a fixed list you fall short of, the day is sized to the capacity you actually have — and that’s allowed to change.
Size the day to today
A quick morning check-in — energy, sleep, symptoms, heat — sets the day to Low, Medium, or High. A Low day gets a genuinely shorter list; the rest doesn’t vanish, it simply waits. Nothing is framed as failure.
Cognitive load, not just time
A ten-minute task can cost more than an hour-long one if it’s mentally heavy. Tagging tasks by cognitive load — not just time — means low-load work surfaces first on hard days, so you’re not blocked by the one thing that needs a clear head you don’t have yet.
Recover without penalty
A day that goes sideways isn’t a debt to repay. One tap re-plans the rest of the day — no streaks broken, no completion-rate shaming — and gently picks back up from where you actually are. Here’s more on how to pace a low-energy day.
How Pip helps
Pip is the companion inside Little Hollow. It notices patterns from your own logs — “the last few hot afternoons tended to cost you the next morning” — and always explains why, in plain language, using only what you told it. It never diagnoses, never claims medical certainty, and never stores a diagnosis. The point isn’t to do the most; it’s to work with today’s reality.
Questions
Is capacity-based planning just a to-do app with a mood tracker?
No — the check-in actually resizes the day. A low-capacity day produces a shorter, lower-load plan, and patterns feed back into future planning. Tracking without adapting is the thing this avoids.
Who is this for?
Anyone whose energy or focus meaningfully changes day to day — MS, long COVID, chronic fatigue, migraine, chronic pain, ADHD, burnout — or anyone navigating unevenly demanding weeks.
Is it a medical tool?
No. Little Hollow only reflects patterns in what you log yourself. It’s a planner, not a diagnostic or medical device, and your data stays yours.
