The plan gets made on a Sunday evening. You've had coffee, the week ahead looks open and orderly, and somewhere in the glow of good intentions you decide: workouts at six a.m., five days this week. It doesn't just feel possible. It feels easy. You can already picture the version of you who does it — laces tied, out the door, smug in the dark.
Then Thursday arrives. It's 5:45 a.m., the room is cold, you slept badly, and the plan feels like it was written by a stranger.
In a meaningful sense, it was. The person who made the plan and the person who has to keep it were in two different states — and psychology has a name for the blind spot between them.
Two versions of you make every plan
The behavioral economist George Loewenstein called it the hot-cold empathy gap. His research on visceral states — hunger, fatigue, stress, craving, pain — found that we are remarkably bad at predicting our own behavior across states. When we're in a "cold" state (calm, rested, unbothered), we systematically underestimate how much a "hot" state will change what we want and what we're capable of. And when we're in a hot state, we can barely remember what the cold one felt like.
The gap runs both directions, but the direction that wrecks habits is the first one. Planning almost always happens cold. You decide to eat better on a full stomach. You commit to early workouts while comfortably awake at 8 p.m. You resolve to write every evening during a quiet weekend when nothing is demanding your attention. The self doing the planning literally cannot simulate the self who will do the executing — the one who is tired, stressed, hungry, or simply mid-week and worn thin.
This is not a character flaw. It's a limitation of imagination. Visceral states don't leave good memories; they leave summaries. You know intellectually that 6 a.m. feels bad, but knowing about tiredness and feeling tired are different kinds of knowledge, and only one of them was in the room when you made the plan.
Feeling strong-willed makes it worse
Here's the crueler twist. In 2009, Loran Nordgren and colleagues published research in Psychological Science on what they called the restraint bias — an inflated belief in one's own capacity for self-control. In one study, smokers trying to quit rated their own impulse control, then chose how much temptation to expose themselves to. The ones most confident in their willpower put themselves in the riskiest situations — and were the most likely to relapse.
The pattern generalizes uncomfortably well to habits. The moment you feel most capable — right after a burst of motivation, a good week, an inspiring book — is exactly the moment you're most likely to overcommit, because confidence in future self-control leads you to design plans that require heroics. Feeling strong-willed isn't a resource you're banking. It's a state, and states pass. The plan, unfortunately, stays.
Distance turns plans into abstractions
There's a third force widening the gap. According to construal level theory, developed by psychologists Yaacov Trope and Nira Liberman, we mentally represent distant events abstractly and near events concretely. "Next month" is a watercolor: become a runner, get healthy, be disciplined. "Tomorrow at six" is a photograph: the specific alarm sound, the cold floor, the missing sock, the meeting you have to prepare for by nine.
Habit plans are made at watercolor distance and kept at photograph distance — and obstacles only exist in photographs. From far away, a daily workout is a value you hold. Up close, it's forty minutes that have to come from somewhere, competing against everything else that morning actually contains. This is a close cousin of what Daniel Kahneman and Amos Tversky called the planning fallacy: when we forecast, we imagine the best-case version of events and quietly file the obstacles under unlikely, even though obstacles, in aggregate, are the likeliest thing there is.
So the overcommitment isn't one mistake — it's three stacked together. You plan in a cold state for a hot one. Confidence inflates the ask. And distance hides every concrete thing that will get in the way.
Plan for the person who actually shows up
The fix is not to want less. It's to aim your planning at the right person: not the inspired self who writes the plan, but the ordinary, somewhat-depleted self who has to live it.
A useful instrument for this is the worst-day test. Before you commit to a habit, ask: would I still do this on a bad Thursday? Not a catastrophe — just a normal bad day, the kind you have a few of every week. Short sleep, low mood, a schedule that ran over. If the honest answer is no, the plan isn't a plan; it's a wish with a start date. Shrink it until the answer is yes. Ten minutes instead of forty. One page instead of a chapter. A walk instead of a run.
This feels like lowering the bar, and cold-state you will resist it, because cold-state you is certain the big version is doable. But the bar for a habit isn't impressive; it's repeatable. A version you keep on bad days is worth more than a version you abandon by week two, because repetition — not intensity — is what makes behavior automatic. Ambition belongs in the trajectory, not the daily quota. You can always do more on a good day. The plan just shouldn't require it.
Two smaller adjustments help close the gap further. First, plan tired. If you must design your week, do it at the end of a long day rather than in a Sunday-morning glow — a mildly depleted state is a far better simulation of your executing self than an inspired one. Second, plan from evidence, not projection. Your imagination can't feel next Thursday, but your recent record can stand in for it. If the last three weeks show you actually exercised twice a week, then twice a week — done reliably, maybe done slightly better — is the honest starting point. The most accurate forecast of your future self is not how you feel right now. It's what you actually did last week.
None of this makes motivation useless. Motivation is wonderful at choosing direction — what matters to you, what kind of person you're becoming. It's just a terrible estimator of capacity. Let the inspired self pick the destination, and let the tired self set the pace. When those two stop negotiating against each other, plans stop collapsing, and something quieter and more durable takes their place: a routine that fits inside a real life.
Small enough for your worst day
This idea — commit to what your ordinary self can keep, not what your inspired self can imagine — is the premise Cadence is built on. Instead of asking you to draft a grand regimen in a motivated moment, it helps you start with steps small enough to survive a bad Thursday, then shows you your actual record, so next week's plan grows out of evidence rather than optimism. The ambition stays; it just moves into the trajectory, one kept promise at a time. If you're tired of writing plans for a version of yourself who never shows up, you can start smaller at cadence.lumenlabs.works.
