The Small Promises Muscle
Every commitment you keep or break trains one of two muscles, and the small ones set the pattern.

Holiday's account of where discipline actually comes from: not from a single large decision but from the accumulated record of promises you made to yourself that nobody else knows about. Breaking the little ones trains the muscle that makes excuses; keeping them trains the muscle that says you do what you say. The difficulty is that these commitments carry no external stake, so nothing enforces them but you. The companion move is recovery: when you break one, the model is falling off a wagon that is still rolling, so you can rejoin it now rather than treating the lapse as a verdict on your character.
Origin
Crystallised for Holiday by a scene in Cormac McCarthy's The Road, and reinforced by his own experience that a writer is always assembling reasons not to write today.
Core principles
- 01If you break the little promises you will break the big ones.
- 02You are building one of two muscles with every commitment, whether or not you notice.
- 03These promises have no external stake; only you can enforce them.
- 04The wagon keeps rolling, so you can rejoin it at any moment.
- 05All-or-nothing thinking is convenient because it gives you an exit.
How to run it
- 1
Make the small promise explicit
State the specific commitment to yourself: I will get up at six, I will have vegetables tonight, I will sit down and write. Specificity is what makes the promise checkable later.
Pro tip Bartlett's observation is that the size of the commitments you keep correlates with the size of the payoff in self-story and self-esteem.
- 2
Keep it when nobody is watching
There is no embarrassing forfeit, no public stake, nobody who will notice. Keep it anyway, because that absence of enforcement is precisely what makes the rep count.
Watch out The alarm going off at six and the reasoning that you do not have to be anywhere today is the exact moment the other muscle gets trained.
- 3
Use a physical practice as the training ground
A daily physical commitment gives you a reliable, dated instance of telling yourself you will do a hard thing and then doing it while the excuse presents itself.
Pro tip The mid-effort moment where you could quit unobserved is the most valuable part of the rep.
- 4
When you break one, do not identify with the break
Identify with the person you want to be and know you can be, not with the lapse. The failure is an event, not a description of you.
Watch out The spiral runs: broken commitment lowers esteem, lower esteem breaks the next commitment, and the self-story hardens.
- 5
Get back on now, not tomorrow
Sit down and do a little bit immediately. A bad week of being over-scheduled, distracted or ill says nothing about right now and nothing about tomorrow.
Pro tip Better than sitting down tomorrow is sitting down now; the restart is what begins the process again.
In the wild
In Cormac McCarthy's novel, a father and son sitting at a campfire have agreed to split everything evenly. The father, trying to be kind, gives the boy a little more of the hot chocolate. The boy is upset and points out the promise, and the father answers that if you break the little promises you will break the big ones.
→ Holiday takes it as the governing principle for commitments to yourself, not just to children: the size of the promise is irrelevant to what breaking it trains.
You set the alarm for six, it goes off, you hit snooze, you hit snooze again, and you reason that you do not actually have to be anywhere today so you can wake up whenever. Holiday points out that writing works the same way: writing is not fun, having written is fun, so you are always generating reasons you do not have to do it today.
→ Either way a muscle got built. One version says you keep the commitments you make; the other says you make excuses and cannot be counted on.
In sobriety circles people talk about falling off the wagon. Holiday likes the image because the wagon is still going: you are either on it or off it, and when you fall, mess up or break a promise, it has not disappeared. The alternative script is deciding you are worthless and spiralling.
→ Reframing the lapse as a rejoinable position rather than a character verdict restores the ability to restart the same day.
Common mistakes
Going all or nothing after a lapse
Holiday notes people do not realise that all-or-nothing is convenient: it hands you an off switch. Seven missed days become a reason to abandon rather than a fact about the last seven days only.
Treating a broken promise as evidence about who you are
Deciding you are worthless converts one missed commitment into a lowered self-opinion, which makes the next commitment likelier to break, and the story becomes self-confirming.
Only making promises with external stakes
Relying on public forfeits and accountability partners means you never train the private muscle, and the moment nobody is watching the whole structure stops working.
Is it for you?
Best for
People who have repeatedly failed to sustain habits and have concluded they lack discipline as a trait, and anyone whose self-story has degraded through a run of broken commitments.
Not ideal for
People already over-committed and burning out, for whom the answer is fewer promises rather than better adherence to the existing pile.
From the transcript
“Dad if you break the little promises you'll break the big ones”
“you're building the muscle either way you're either building the muscle that says I do what I say I keep the commitments that I make”
“I like the idea that the wagon is going and you're either on the wagon or off”
“it's actually very convenient to be all or nothing right like that way because it's giving you an out or an off”
