There is a particular kind of optimism that arrives on a Sunday evening.
Tomorrow, you decide, will be different.
You will train three times. Eat properly. Drink more water. Get your steps in. Go to bed on time. Maybe even stretch.
You have entered your highly organised era. Slay.
Then Tuesday happens.
You sleep badly. Work is chaos. Your toddler has a meltdown because you peeled the banana she specifically asked you to peel. Dinner is still frozen and the 60-minute workout you confidently scheduled now feels about as appealing as doing your tax return.
And that is often where the real problem begins. Not because you missed the workout. But because your brain quietly turns “I can’t do what I planned” into “I’ve messed it up.”
So you skip today. Tomorrow feels slightly off too. Then somehow Monday becomes the next sensible time to begin again.
This is the all-or-nothing cycle, and it is one of the most effective ways to make consistency unnecessarily difficult. Because sustainable behaviour change is not really about becoming better at executing the perfect plan. It is about becoming better at continuing when the plan stops being perfect.
Your brain learns through repetition, not perfection
We often talk about consistency as though it is a personality trait. Some people are disciplined. Some people just “have willpower”, but habits are less glamorous than that.
When a behaviour is repeated often enough in a similar context, the brain begins associating the situation with the action. Morning coffee becomes linked with a walk. Finishing work becomes linked with changing into gym clothes. Nursery drop-off becomes linked with going for a run or doing your training.
At first, the behaviour requires conscious effort. You have to remember it, decide to do it and sometimes talk yourself into it. Over time, repetition makes that process easier. The cue begins doing more of the work.
That is essentially what habit formation is: reducing the amount of negotiation required to begin.
Which is why a plan that only works when you have maximum energy, motivation and time is a pretty terrible habit-building tool. Life is too variable. There will be deadlines, sick kids, hormones, holidays, broken sleep, social plans and entire days where putting on a sports bra feels like a personal attack.
If every disruption means abandoning the behaviour completely, you keep interrupting the repetition your brain needs. The answer is not necessarily to try harder. Sometimes it is to make the behaviour easier to continue.
Enter: the 7 out of 10
When I talk about 7 out of 10, I do not mean doing everything badly.
I mean letting go of the idea that the only worthwhile version of something is the ideal version.
Ask yourself:
What is the version of this behaviour I can actually do today?
You planned a 45-minute strength session. You have 20 minutes. Do 20.
You planned a run. You are shattered. Walk.
You planned three sets. Do two.
You cannot get to the gym. Train at home.
The physiological benefit of ten minutes of training is obviously not identical to forty-five minutes. That is not the point.
The shorter session is doing two jobs. It gives you some training stimulus, yes. But it also keeps the behavioural thread intact. You are still someone who showed up!
That matters more, because one of the most interesting findings from habit research is that missing an occasional repetition does not appear to destroy the habit-building process.
One missed session is rarely the real problem. The problem is what we make it mean.
I missed Tuesday becomes I’ve fallen off.
And I’ve fallen off becomes I need to start again.
Suddenly a single missed workout has acquired an entire storyline. Your brain does not require the drama. It requires the next repetition!
Consistency is the ability to return
I think we have misunderstood consistency. We tend to imagine it as an unbroken line, three workouts every week, plus 10K steps every day, and don't forget perfect meal prep, and eight hours of sleep. Forever.
But real consistency looks much messier!! Maybe 2-3 sessions this week. Two shorter ones next week. A disrupted week after that. Then three again.
The pattern contains variation, but the behaviour remains part of your life.
That is a much more useful definition of consistency: not never being disrupted, but shortening the distance between disruption and return.
And this is where rigid plans often let us down. If your plan contains only one acceptable option, any change in circumstances creates a new problem to solve.
You were meant to train at 6pm. Now it is 7:30. What happens?
If the only answer was “60-minute gym workout at 6pm”, your brain has to redesign the plan while already tired and stressed.
For anyone who struggles with executive function, something I know very well, that extra decision-making can be enough to kill the whole thing. So make the decision beforehand.
Instead of one plan, have three.
The ideal version.
What you do when time and energy are good.
The 7/10 version.
The shorter, simpler version that still meaningfully moves you forwards.
The minimum version.
The smallest action that keeps you connected to the routine.
Suddenly the day has not “gone wrong”. You simply choose another route. You adapt to life and don't throw goals in the bin the minute life gets challenging.
Your environment matters more than another motivational speech
Motivation is lovely when it appears. We love her. Unfortunately, she is wildly inconsistent!
Stress changes. Sleep changes. Energy changes. Children wake up at 4am for absolutely no discernible reason.
If your behaviour depends on feeling motivated, you will spend a lot of time waiting. A better strategy is to reduce the number of decisions involved.
Train on broadly consistent days.
Put your running shoes somewhere visible.
Keep a few meals you can make without thinking.
Know what your 20-minute workout is before you need it.
And use simple if–then plans.
If work runs late, then I will train at home.
If I sleep badly, then I will walk instead of doing intervals.
If I cannot complete the full session, then I will do two sets.
You are effectively making the decision while your rational brain is online instead of leaving it to tired Wednesday-night you.
She has enough going on.
Stop making yourself earn the right to continue
There is another strange thing all-or-nothing thinking does. It makes us feel as though a mistake requires compensation.
You miss a workout, so you need to do extra tomorrow.
You eat a takeaway, so Monday needs to be “clean”.
You have a busy week, so the next week becomes a dramatic comeback tour. None of that is necessary.
You do not need to punish yourself back into consistency. One late night does not erase your sleep habits. One meal does not undo your nutrition. One missed workout does not delete the training you have already done.
You simply return to the next useful behaviour. No catch-up. No restart. No Monday required.
Maybe the real habit is coming back
We spend a lot of time trying to build habits that we never break.
I think there is another skill worth practising:
becoming someone who comes back quickly.
Because life will disrupt you.
No routine is clever enough to prevent that. The goal is to build one flexible enough to survive it. So this week, instead of asking yourself how to execute everything perfectly, try something different.
For the habits that matter to you, decide:
What does 10/10 look like?
What does 7/10 look like?
What is the minimum?
Then, when real life inevitably turns up, choose the version that fits the capacity you actually have. Not because standards do not matter. Not because every effort is physiologically identical. But because repeated behaviour is what gives your brain the chance to turn intention into something more automatic.
Sometimes progress looks like a brilliant workout. Sometimes it looks like twenty minutes squeezed between work and bedtime. And sometimes the most important thing you do is refuse to turn one imperfect day into a reason to disappear.
You do not need to become endlessly motivated.
You need a plan that still works when you are not.
That is consistency. Not chasing perfect. Just continuing.
