How to be more disciplined (without relying on willpower)

What discipline looks like in the research

Ask people to describe a disciplined person and they’ll picture someone who says no to dessert, gets up at 5 am and grits their teeth through the gym. The research paints a different picture.

In 2012, Wilhelm Hofmann, Roy Baumeister and colleagues gave 205 adults beepers for a week. Several times a day, they reported whether they were feeling a desire, whether it conflicted with a goal and whether they tried to resist. That produced 7,827 reports. As Brian Galla and Angela Duckworth later summarised it, people with better self-control were less likely to report attempts to resist temptation than people with lower self-control. They weren’t winning more battles. They were fighting fewer.

A meta-analysis of 102 studies and 32,648 people (de Ridder et al., 2012) points the same way: trait self-control was more strongly linked to automatic behaviours than to deliberate ones. For desirable behaviours, the correlation was r = .36 for automatic ones versus r = .15 for controlled ones, as Galla and Duckworth reported.

Galla and Duckworth (2015) then tested the explanation directly across six studies with 2,274 people, from teenagers to middle-aged adults. Self-controlled people had stronger good habits (eating healthy snacks, exercising, regular sleep, studying), and in statistical terms those habits mediated the link with better results: more automatic behaviour, less effortful resistance, homework handed in, and even grades and staying in college.

The lesson: discipline is less a personality trait you’re born with and more a set of arrangements you can build.

Willpower isn’t a fuel tank

From the late 1990s, the dominant theory was “ego depletion”: self-control draws on a limited resource, so resisting one temptation leaves you weaker against the next. A 2010 meta-analysis of 83 studies supported it (Hagger et al., 2010).

Then came the stress tests. In 2016, 23 laboratories ran the same pre-registered protocol with 2,141 participants. The effect was d = 0.04, with a confidence interval that included zero (Hagger et al., 2016). In 2021, a project led by Kathleen Vohs, one of the theory’s leading researchers, involved 36 labs and 3,531 participants and used two different procedures. The pre-registered result was d = 0.06, not significant, and the data were four times more likely under “no effect” than under the expected effect. Exploratory analyses found a tiny effect (d = 0.08), somewhat larger in people who said they felt tired.

A related finding: in a set of four studies, Veronika Job, Carol Dweck and Gregory Walton (2010) found that people who believed willpower was limited showed depletion effects, while those who didn’t believe it largely didn’t. That’s one research team’s result, so treat it as a lead rather than a law.

What this means for you:

• Tiredness is real. Being worn out after a long day isn’t imaginary, and it’s a good reason to plan hard things for when you’re fresh.
• “I used up my willpower at work, so I can’t cook tonight” is a weaker excuse than it sounds. Your evening depends more on what’s already in the fridge than on a reserve that’s run dry.
• Rather than trying to have more willpower, try to need less of it.

Strategy 1: act before the urge, not during

Angela Duckworth, Tamar Gendler and James Gross (2016) sorted self-control strategies along the timeline of a temptation. Early on, you can choose your situation (study at the library rather than at home) or change it (leave your phone in another room). Later, you can only redirect your attention, reframe the temptation, or resist the action itself. Because urges grow stronger over time, the early strategies stop the problem while it’s still small.

This isn’t just theory. In a study of high school and college students (Duckworth et al., 2016), students rated early strategies as far more effective than later ones. In two field experiments, students randomly assigned to use situation modification for a week were more likely to meet their study goals than those told to resist in the moment or given no strategy. For the college students, part of the effect came from feeling less tempted during the week.

Practical examples, whatever your goal:

• Money: Sofia in Lisbon deletes the shopping app from her phone; Jamal in Manchester moves £50 to savings on payday before he sees his balance.
• Screens: the phone charges outside the bedroom; social apps leave the home screen.
• Food: you shop after eating, and what you want to avoid never enters the basket.
• Work: the hardest task goes in your first hour, before messages start.

Strategy 2: turn decisions into habits

Every choice you make only once saves you from making it every day. That’s what Galla and Duckworth’s studies suggest self-controlled people do: they rely on routines that no longer require deciding.

To turn a behaviour into a habit, tie it to a fixed cue (a time, a place or an action you already do) and repeat it in the same context. Our guides explain how to anchor a habit to an existing routine and how long it really takes. Two rules of thumb:

• Start smaller than you think. Ten minutes of study at the same time every day beats two hours “when you feel like it”.
• One or two habits at a time. Each new habit needs attention until it becomes automatic.

Strategy 3: precommitment

Precommitment means deciding now, while you’re calm, and making it harder or costlier to back out later. The best-known field test comes from the Philippines. Xavier Giné, Dean Karlan and Jonathan Zinman (2010) offered smokers a savings account called CARES: they deposited money for six months and got it back only if a urine test showed they’d quit; otherwise it went to charity. Only 11% of those offered it signed up, but smokers randomly offered CARES were 3 percentage points more likely to pass the test at six months, and the effect held in surprise tests at twelve months.

Three percentage points looks small, but across a whole group of smokers it’s a real effect from a product most people turned down. Everyday forms of precommitment:

• tell a colleague you’ll send them the draft on Friday;
• book and pay for a class instead of planning to “go running”;
• schedule an automatic transfer to savings on payday;
• pair a task you avoid with a pleasure reserved for it (researchers call this temptation bundling; see our guide on how to stop procrastinating).

Strategy 4: plan for rest days and slips

A rigid system breaks at the first exception. Planned rest days (a Sunday off from the gym, a lighter week during exams) keep the habit alive instead of turning one missed day into an abandoned goal. When you slip, the useful question is not “why am I so weak?” but “what in my situation made this easy?”. Then fix that. If the problem is motivation rather than discipline, our guide on getting motivated covers that side.

A simple system, and a 15-minute weekly review

Here is the whole approach on one page:

1. Choose 1 to 3 habits tied to what matters this season (health, money, a project).
2. Give each one a cue: a time, a place or an existing routine.
3. Shape the situation for each: what to remove, what to prepare in advance.
4. Add one commitment for the hardest one.
5. Check in each evening: did I do it, yes or no? No judgement, just data.
6. Review once a week with the checklist below.

Frequently asked questions

Can you train yourself to be more disciplined?

Yes, but not mainly by “strengthening” willpower. What changes with practice is your setup: habits that run on cues, situations with fewer temptations, and decisions made in advance. Research on self-controlled people suggests that’s how they operate.

Is discipline more important than motivation?

They do different jobs. Motivation gets you to start; habits and a good setup keep you going on the days motivation is low. Relying on motivation alone means relying on your mood.

Why do I lack self-discipline in the evening?

Tiredness is a real factor, and exploratory results in the 2021 study showed slightly larger effects in people who felt fatigued. But evenings are also full of cues: the sofa, the phone, the fridge. Change those, and schedule demanding tasks earlier in the day.

How long does it take to become disciplined?

There’s no fixed date. A new habit typically takes weeks to months to become automatic, depending on the behaviour and how consistently you repeat it. Judge progress week by week in your review.

In short

Disciplined people aren’t fighting harder; they have fewer fights, because their habits and surroundings do most of the work. Your first step this week: pick one habit, remove one temptation from your environment, and put a 15-minute weekly review in your calendar for Sunday.
