New Year habits that last: how to start in January and still be going in March

By Callum Matthews · · 5 min read

Every January the same two things are said: that resolutions are pointless because everyone breaks them by February, and that this year is different. The research is kinder than the first claim and more useful than the second. Resolutions work better than their reputation, and the ones that last share a shape you can copy.

Resolutions work, compared with not resolving

John Norcross and colleagues followed 159 people who made a New Year's resolution and 123 who wanted to change the same kind of thing but had not resolved to, and checked in with both groups for six months. At the six-month mark, 46% of the resolvers were still succeeding, against 4% of the non-resolvers [2]. The people who are usually mocked for making resolutions were doing eleven times better than the people who did not bother.

A larger, more recent study points the same way. Martin Oscarsson's team at Stockholm University followed 1,066 people through a full year of their resolutions and found that 55% considered themselves successful at the twelve-month follow-up [3]. Not everyone. But not the ten percent the folklore quotes either.

Why January works: the fresh start effect

Hengchen Dai, Katherine Milkman and Jason Riis documented what they called the fresh start effect: searches for "diet", gym visits and commitments to goals all spike after temporal landmarks, the new year most of all, but also new months, new weeks, birthdays and the start of a term [1]. A landmark closes the books on the old you and opens a new accounting period, and people are more willing to invest in a new period.

Two things follow. First, use it: the energy is real and it is free, so start on the landmark. Second, plan for it to fade, because it does, typically within a few weeks. The fresh start gets you to the starting line. Something else has to carry you from week three to week ten.

A resolution is a fresh start looking for a system. Give it one before the feeling wears off.

Phrase it as something to do, not something to stop

The most actionable finding in Oscarsson's study is about wording. Resolutions framed as approach goals, things to start or do more of, succeeded 58.9% of the time; resolutions framed as avoidance goals, things to stop or do less of, succeeded 47.1% of the time [3]. Same people, same year, twelve points of difference from how the goal was written.

This matters for mornings specifically, because the natural January resolution is an avoidance one: stop snoozing, stop scrolling in bed, stop being late. Rewrite each as the thing you will do instead. Not "stop snoozing" but "walk three hundred steps when the alarm rings". Not "stop scrolling" but "read ten pages before the phone". The avoidance version gives you nothing to do at 6:45. The approach version is a mission.

Give it a daily cue

Habits form through repetition after a consistent cue, and in Phillippa Lally's UCL study they took 66 days on average to become automatic, with a wide range [4]. A resolution made on 1 January and performed daily is, on that average, automatic by around 7 March. That is the finish line, and it is why "still going in March" is the right test. Past it, the behaviour runs on the cue rather than on you.

The cue has to fire every day, in the same context, without you remembering it. For a morning resolution there is one obvious candidate: the alarm. It is the only event in your day with a guaranteed time and a siren attached, and nothing you resolve to do in the morning can happen before it.

Decide the when and where in advance

Peter Gollwitzer's research on implementation intentions shows that a plan in the form "when X happens, I will do Y" roughly doubles follow-through compared with a goal alone [5]. Norcross's resolvers who succeeded were distinguished by readiness and by having the skills to change, not by wanting it more [2]. A resolution with a time, a place and a trigger is a plan. A resolution without them is a wish.

Plan the miss

You will miss a day. Lally's data says a single miss does not materially affect habit formation [4]; it is the second and third consecutive misses that turn an exception into a new normal. So decide now what a missed morning means: nothing, provided the next one happens. Write it down with the resolution. The people who quit in February are rarely the ones who missed a day; they are the ones who treated the miss as proof.

Build it: a January resolution that lasts

  1. Pick one. One resolution, not five. The others can stack on it in March.
  2. Write it as an approach goal. Something you will do, with a number: three hundred steps, one page, thirty seconds of push-ups.
  3. Attach it to a daily cue. "When the alarm rings" is the strongest one you own.
  4. Make it small enough for your worst morning. The floor is the habit. Raise it in March, not in January.
  5. Decide what a miss means. Nothing, if the next day happens.
  6. Measure the cue, not the outcome. Count mornings the resolution ran, not kilos or pages. The outcome follows the count.
  7. Check in at day 66. If it feels automatic, add the next one. If not, keep going; the curve is still rising.

This is, not by accident, what First Light does. The resolution becomes the alarm's mission. The alarm is the cue, it will not stop until the mission is done, the mission has a floor you can clear half asleep, the streak forgives a miss and counts scheduled mornings, and the ranks land at 7, 30 and 66 mornings. The fresh start effect gets you to 2 January. The alarm gets you to March.

Questions people ask

What percentage of New Year's resolutions succeed?

Higher than the folklore suggests. In a six-month follow-up study, 46% of people who made a resolution were still succeeding, against 4% of people who wanted the same change but made no resolution. In a larger Swedish study, 55% considered themselves successful a full year on, and people with approach-oriented goals did better than those with avoidance-oriented ones.

What is the best resolution to choose?

One phrased as something to do rather than something to stop, small enough to do every day, attached to a cue that already happens daily. "Walk three hundred steps when the alarm rings" beats "stop snoozing", on the evidence and in practice.

Do I have to start on 1 January?

No. The fresh start effect works for any temporal landmark: a Monday, the first of a month, a birthday. If January went badly, February the first is a fresh start too. The landmark gives you the push; the daily cue keeps you moving after it fades.

How many resolutions should I make?

One. Every unautomated behaviour draws on the same limited willpower, and January is already full of them. Get one to automatic, around two months of daily repetition, then stack the next on it.

A January habit needs a cue that fires every day. First Light makes the alarm that cue. Set the resolution as a morning mission and the alarm does not stop until it is done, on 2 January and on 14 February. Meet First Light →
