Anti-Burnout Labs · Part 4 of the C.H.A.N.G.E. series
Hard days are not exceptions to the process of change — they’re part of it. Deciding in advance what you’ll do when they arrive is one of the quieter, more underrated moves in sustainable behaviour change.
By this point in the C.H.A.N.G.E. method, you’ve chosen a focus area, connected it to a heartfelt why, and designed a specific repeatable action. On good days — days with enough time, enough energy, enough headspace — following through on that action probably feels manageable.
But good days aren’t the only test of a habit. The harder question is what happens on the days when everything is difficult. When you’re exhausted, or overwhelmed, or something unexpected has derailed the plan. Those days come for everyone, and how they’re handled tends to shape the trajectory of change more than the easy days ever do.
This is what the N step addresses: Non-Negotiable actions. The floor, not the ceiling. The minimum you decide to honour even when conditions are against you.
What the research says about minimum commitments
There’s a concept in psychology called the “what-the-hell effect,” documented by researchers Janet Polivy and Peter Herman in studies on dieting and self-regulation. It describes what happens when people violate a behavioural commitment, even slightly: rather than adjusting and continuing, they abandon the commitment entirely, often overshooting in the opposite direction. One missed workout becomes a week off. One unplanned meal becomes the end of the eating pattern they’d been building.
The effect is driven largely by all-or-nothing framing. When the only acceptable outcome is the full version of the behaviour, a partial day registers as total failure — and once something is framed as failed, the motivation to continue it collapses.
A pre-decided minimum changes that framing. If the full action is thirty minutes of movement and the non-negotiable minimum is a ten-minute walk, then a hard day that produces the walk is still a kept commitment. The continuity holds. The identity — I’m someone who shows up for myself — stays intact. And intact identity, as discussed in the previous post on Heartfelt Why, is one of the most reliable predictors of returning to a behaviour after disruption.
A hard day that meets the minimum is still a kept commitment. The continuity matters more than the amount.
The difference between a floor and a lowered bar
One thing worth sitting with: a non-negotiable minimum isn’t the same as quietly lowering your standards and hoping nobody notices — including yourself.
The distinction is in how it’s set. A floor is decided deliberately, in advance, as part of the plan. It’s the version of the action that acknowledges that life has different seasons and different days, and that sustainability across all of them matters more than optimising for the easy ones. It’s honest about human capacity in a way that aspirational goals often aren’t.
Lowering the bar, by contrast, tends to happen reactively — in the moment, under pressure, as a way of avoiding discomfort. It doesn’t feel the same, internally. Most people can tell the difference when they reflect on it.
Setting a floor in advance is actually an act of self-knowledge. It says: I know what hard days look like for me, and I’ve already decided what I can still offer myself on those days. That’s a more considered position than assuming every day will be equally resourced.
Nice-to-have versus non-negotiable
The workbook separates actions into two categories: non-negotiable and nice-to-have. This is a useful distinction that rarely appears in standard goal-setting frameworks, which tend to treat all planned behaviours as equally obligatory.
Nice-to-haves are the fuller, richer version of the action — the things you do when conditions are good and you have more capacity. They’re worth doing, and worth planning for, but they’re not what defines whether a day counts. They live above the floor.
Having both explicitly named does a few things. It makes the good days genuinely satisfying — you’re not just meeting a minimum, you’re doing more than required. And it makes the hard days survivable, which is where most behaviour change attempts quietly end.
Some people find it useful to think of this as a spectrum rather than a binary. On the best days, everything. On average days, the full planned action. On hard days, the non-negotiable minimum. On genuinely difficult days, the smallest possible gesture that still counts as showing up — even just a moment of conscious intention toward the change.
What counts as a minimum
The right minimum is personal, and it’s worth thinking about carefully rather than picking something arbitrarily small. A few questions that tend to help:
What could you do even on your worst recent day? Think back to the hardest day in the past few weeks — not a crisis, just a genuinely depleted, difficult day. What would have been possible then, without heroic effort?
Is it still connected to the change you’re making? The minimum should be a genuine expression of the focus area, not a token gesture that’s so removed from the actual goal it barely counts. If the focus is nutrition, the minimum might be one conscious food choice, not just drinking a glass of water. Small, but still directionally relevant.
Can you say yes or no to it clearly? The same measurability test from the Action step applies here. If you can’t clearly tell whether you did it, it needs to be more specific.
Planning for hard days rather than hoping they won't come
There’s something in behaviour change research called if-then planning, related to the implementation intentions discussed in the Action post. Applied to difficult days, it sounds like: if today is genuinely hard and I can’t do the full action, then I’ll do this instead. Deciding that in advance — rather than improvising under pressure — significantly reduces the cognitive load of the moment and the likelihood of the what-the-hell effect taking over.
It also shifts hard days from being threats to the process into something that was already accounted for. The plan includes them. They’re not deviations — they’re a scenario that was anticipated and prepared for. That reframe alone can change how a hard day feels while it’s happening.
A hard day that meets the minimum is still a kept commitment. The continuity matters more than the amount.
On perfectionism and the process of change
For anyone who tends toward perfectionism, the non-negotiable step can feel uncomfortable — as if naming a minimum is the same as accepting mediocrity. It’s worth examining that instinct carefully, because perfectionism in behaviour change tends to produce the opposite of what it promises.
Research by Joachim Stoeber and others on perfectionism and self-regulation suggests that perfectionistic self-presentation — the need to appear to be doing it right, or to meet self-imposed high standards consistently — is associated with greater emotional distress after setbacks and lower persistence over time. The internal pressure to do it perfectly often makes doing it at all more fragile.
Minimum commitments are, in a sense, a structural antidote to that pattern. They make it harder to fail completely, which makes it easier to keep going. And keeping going, across weeks and months and seasons, is what actually produces change — far more reliably than any single perfect stretch.
If you’d like to work through your own non-negotiables — and the nice-to-haves that sit above them — the C.H.A.N.G.E. Workbook has prompts that make it concrete. You can check it out HERE.
Next in the series: G (Gamification), on why tracking progress in a way that feels engaging matters, and what the research on motivation and reward tells us about designing a system you’ll actually want to return to.
