It took me a few days to become a smoker, and a few weeks to get to the point of not wanting to smoke again (some decades later).

It took me a week or so to start having a healthier breakfast and it become part of my routine, and I've been trying to have healthier lunches for years now (and still regularly fail, normally because at lunchtimes I'm tired, stressed and yearning for comfort foods like sandwiches and snack bars).

I think anyone who believed exactly 21 days was the magic number for all habits, for all people, was grossly naive.

But what I do find is that after 21 days it's no longer novel, it's just what you do, if somebody asks you what you do about X, you no longer say "I'm trying this new thing around X, and...", you tell them your new habit. Identifying that habit as part of who you are is key to it being sticky. For some people, and for some habits, that might be true after a week, or it might take a year, but it's an important step, and if you want that habit to stick you should get to it as fast as you can.

    Jan 1, 2024, I made a resolution to change my diet (basically small, very simple meals with one cheat meal a week). I'd probably made a dozen such resolutions before without much success, but for some reason this one stuck right away. I never even had trouble sticking with it, and lost a pound a week over the next 10 months. Then I met my girlfriend and we went out to eat a lot, and that broke the habit. It seems like big life changes can reset habits.

    I wish I knew how I did it, because I've been unable to regain that same "this is just what I do now and it's fine" level of acceptance that seemed to be the key.

      Sometimes it’s as simple as “doesn’t hurt enough yet”

      My grandpa was a liter of wine per day (or more) kinda guy. Then he hit his 70’s and it didn’t feel good anymore. So he stopped and hasn’t had a glass of alcohol since. Just doesn’t feel like it. Even when others drink around him.

                - Nicotine pouches damage teeth.

    That's a shockingly short amount of time for smoking. For me, after a few weeks I'd say some of the worst cravings had passed. But for a good year or two afterwards they'd occasionally come back, albeit briefly. I quit about 15 years ago, but given the right situation I can still feel it.

      But then some place around 6 months, where you realize that it is impossible that this day, today, is the day I will end my streak.

    What is your healthier breakfast? I never really learned what is considered a healthy breakfast.

    • cultofmetatron 12 hours ago

      > I never really learned what is considered a healthy breakfast.

      one of the big problems in the standard american diet is that we treat breakfast like a dessert.

      1. cereal has around 15-30 grams of sugar in addition to various artificial flavors and additives.

      2. pancakes and waffles? an irresponsible carb bomb that you douse in syrup and whipped cream.

      3. breakfast sausage is basicly low quality meat mixed with fat. at least by itself its not high in sugar but then people normally have it with pancakes.

      4. granola? na, more sugar.

      Reality is that almost all "breakfast foods" are junk.

      my advice is to steak to black coffee and a slice of fish or steak for most people. I like to have black coffee and sardines. seems to keep my mood stable througout the day.

    • cogman10 15 hours ago

      Mine is a bowl of old fashion oats, frozen mixed fruit (I like a blueberry/blackberry mix), and maybe some non-fat plain greek yogurt and/or a glass a of plain soy milk.

      Alternatively, a couple of scrambled eggs with a piece of toast and a bananna is fairly healthy.

      A fried egg on an English muffin also isn't a terrible way to start the day.

      Target ~400 cals, Try and get some protein and fiber in there. Watch out for saturated fats and high sodium (see the DASH diet for tips). If you are diabetic or risk diabetes, check out the glycemic index and shoot for low GI foods.

      That'd be my advice (I'm not a doctor, what I'm suggesting could be 1000% wrong.)

      • electrosphere 8 hours ago

        I used a CGM recently. I tried breakfast as oatmeal with blueberries and mixed in with peanut butter. It spikes my blood sugar outside the "normal range". I treat oatmeal as once a week treat to avoid food boredom.

        The oatmeal was a "big bowl" variety from a packet. I heard rolled oats might be better but it's a hassle to cook.

        Most days breakfast is scrambled eggs (3 eggs), spinach, cheese. Sometimes I add tuna or avocado for variety. That keeps things stable.

        • pastage 7 hours ago

          Yeah that tracks. In the mornings your body is still in sleep mode so carb intake will take longer to be absorbed. If you have diabetes you need more insulin and a longer time for it to have affect. So for sure eating slow release carbs will help with the peak. Eating fats like cheese/avocado/oil will dampen the peak as well, eggs have 1% carbs and weighs almost nothing.

          Just pointing out that the peak is just how the body works.

          The packet probably was rolled oats. The other main option is steel cut, which take longer to cook. When I used to eat steel cut oats for breakfast, I used a rice cooker with a timer so it would be ready when I woke up. On the weekend, I'd use milk instead of water since I had plenty of time to wait for it to cook instead of setting it up the night before, which made using milk a bit of a risk.

      I think part of the problem is we don't really know what a healthy diet looks like. We can point to what is probably unhealthy: eating tons of sugar filled items is probably bad, eating a lot of fried food is at least questionable, but beyond that we really don't know. The research is either poorly done, impossible to do, or you can find studies that go both ways.

        I mean a healthy diet is a variety of fruits and vegetables, with a decent supplement of whole grains and occasional lean meats and eggs. Minimally processed as much as possible - whole ingredients should be the majority of calories.

        The details don’t matter so much, as long as you get a variety and generally stick to the above guidelines.

        I think you can judge how healthy a diet is by how many people get diseases, malnutrition or premature death as a result of a diet, and almost nobody is going to suffer because of that diet plan above.

        • pastage 7 hours ago

          This seems like good and standard advice does not seem to be controversial at all. I think the question is which practical foods are healthy.

          • californical 7 hours ago

            I agree, it’s a trick question because no food is healthy by itself, foods are only healthy as part of a whole. And as long as your foods usually fit with the basic standard advice, then you’re eating healthy foods.

            If you have cheese as a large component of almost every meal, then you’re deviating a lot from the basic advice, so it’s not healthy. If you have a bit of cheese on your breakfast of eggs and toast a couple times per week, then it’s healthy.

What has been most reliable for me has been instead of going from bad habit A to good habit Z, I just replace A with the easiest alternative that is less bad than A.

Obviously, this means going from A to Z can take years instead of weeks. Though, from my own personal experience and from what I see of others, trying to go too quickly from A to Z just results in whiplash and irractic behavior--where I have seen it work is when there is an existential crisis demanding that the behavior change.

If I'm counting the days to form a habit, I'm not really interested in forming that habit. That's just a means to an end for me. Maybe I'm waking up earlier to have more time for myself, or I'm developing a reading habit so I can finally finish reading Hegel.

In all these cases the habit is secondary. It's all discipline and pain.

But I think there is a better relationship to be had with habits. One that isn't unfairly tied to productivity. One that I can just enjoy the struggle until I form that routine, or I build up the familiarity or the skill to do something. That kind of attention changes something fundamental about my relationship with what I'm trying to internalize and make a part of myself. It's to learn to be constantly learning and improving without making it a burden or a chore.

I happen to be taking a Team Lead course, and forming habits came up yesterday. 21 days weren't mentioned explicitly, the time frame was "a few weeks". We were given 6 criteria when forming a habit:

1. Tangible - you need to pick a tangible action that is observable. If you're trying to fix a part of your behavior you can't pick "I'll pay more attention" as a habit to correct yourself, instead you should write a note or say some phrase.

2. Up to me - don't form a habit that requires outside factors. If you want to start jogging, don't ask your neighbor to jog with you. Each time he's not available, you'll have an excuse not to jog.

3. Swallow the frog - don't push it off. This isn't a well defined criteria, the idea is to minimize excuses (like #2).

4. Daily - a habit needs to be formed by taking action every day.

5. Trigger - your action needs a trigger. This can be an internal (feeling hungry), external (a timer on your phone), or contextual (every morning, every time you walk into a conference room).

6. New - it's very hard to form a habit if you've already tried and failed. Pick an action that you haven't already tried.

There was also an important note that changing behavior often requires multiple steps. The instructor gave the example of using dental floss. It's hard to go from nothing to flossing every day, so break it into:

1. Every time you go into the bath room in the evening, pick up the dental floss, and put it down.

2. After picking up the floss becomes a habit, cut a piece of floss, and throw it out.

3. After cutting the floss becomes a habit, floss a few teeth.

And so on.

In Indian culture, people do a ritual for 40 days without trying to make a habit, and my reading is that habit forming is the purpose. Sometimes what you do it not directly related to your goal, let's say fasting or going to temple or whatever, but I guess 40 days of thinking about your new-routine-adjacent-goal makes you obsess about it and try to make it happen.

So twice what is being discussed here.

IMO, getting a habit might need a "click", a resolution.

I tried many times to get into exercise, but only got into a regular schedule (daily) recently. I don't even know what happened but there is definitely a click. The number of days is not so important. Something inside just told me to do it. Same with fasting. Somehow I got into 72-hour water fast with zero preparation and "habit" a few months ago and have been doing it once or twice a month.

How to get the click is more interesting. I wish I could generate those clicks for things I want to do but not dying to do.

I suspect there're other factors to forming habits.

Forming a running habit is probably harder than say heroin.

I also recall from the "atomic habits" book, that you can chain habits together.

The idea was that if you already have a habit of getting out of bed in the morning, you could hydrate. Just say "as soon as I get out of bed, drink a glass of water" and it is easier to form the habit.

blueyes 17 hours ago

B.J. Fogg makes this point in his book Tiny Habits. And his point *is* that you can form a habit in much less than 21 days, let alone 66.

This whole question revolves around the effort/reward ratio of a behavior. When people talk about ~21 days, they're talking about doing a hard thing until it's second nature and seems easy.

But there are other ways to make something seem easy, and there is another component in the ratio: reward. That is, even if effort stays the same, you can wire a habit by making the behavior more rewarding. (This is why people are able to get addicted to a substance after one dose -- because they can't forget the state they entered ... and it was so easy to get there.)

So the takeaway here is the you can wire habits by decreasing the amount of effort to do something that you think is good for you -- eg if you want to hydrate more, place a glass near the sink so you drink water when you get out of bed in the morning -- *and* by increasing the reward. The whole trick is getting the ratio right.

Cliche Silicon Valley example. I did an ice plunge, and it gave me a day long plunger's high. I didn't need to plunge for 21 days to get the habit. I started doing it 3 times a week after that, because I knew what I had to do to feel good.

This actually gets to something Huberman calls "duration-path-outcome". Getting clarity on what you have to do (path); how long it will take (duration); and what the payoff is (outcome), can do wonders for motivation. Confusion kills action (and for that matter, all deals, since habits are just deals we make with ourselves). If you can get clarity, reduce the effort, and increase the amount of reward and your confidence in it, I think you can get to new habits really quickly.

Fwiw, I wrote a little bit about forming habits here: https://vonnik.substack.com/p/state-changes-work-and-presenc...

When I shifted to Bangalore and in March 2023, I faced water shortage (found out later it was a issue in the water supply pipes) I signed up to gym practically immediately, and used to go all days back then, just to have a bath. Hit the treadmill for 30-40 mins or lift for an hour,then have a bath. Used to gym earlier in 2022 but never got that to be a habit, but the habit stacking thing worked really well. Now that the water issues are largely sorted, I still go to the gym practically 4-5 days a week.

    I think a good litmus test for a lot of behaviors is: "is this behavior serving me, or am I serving it?"

      Exactly. I realized alcohol was something that caused me to act in ways that got in the way of my life goals (nothing crazy, just things like I sleep worse after alcohol, I feel worse after alcohol, and I forwent activities I wanted to do).

      After that realization I stopped drinking and have never felt like it again.

      Yes, I agree with you.

Oh, that kind of habit. The good kind. It can take much less than 1 day to form a bad habit. I wonder how that asymmetry really is - were ancient humans less exposed to addictive substances and had no need to evolve a way to stop that? I have no idea what I'm talking about so, I'll end the comment here.

    My theory is that we don't come from a history of plenty or safety, so, in a pre-historical sense, if something feels good that's supposed to be the signal to keep doing it because it is going to go away and you can't really get too much of it.

    We were supposed to overeat because we wouldn't often get a chance. If we could be lazy and survive, then we should be lazy and preserve those calories because a time was going to come when we couldn't. It's the modern world that has all those natural predispositions screwed up. We can enjoy ourselves to excess in ways that we would never be able to in the wild, which then puts us in danger.

    Maybe it's still a honeymoon thing for me but I've been trying out keto diet for few weeks and, anecdotally, now whenever I eat carbs I get a weird high. If you told me that people started farming to do it consistently, I'd believe you. Similarly, if I avoid carbs at all cost even for a day, by night I feel so bad that I must have some. Point is that as far as I can tell eating carbs is a habit/addiction as well, but much good has come from maintaining it.

      I don't remember where I got this quote, but it makes sense to me: "Grains are a cheap caloric source that's allowed for the growth of tightly packed, heavily populated cities. Grains are good for civilizations. They are bad for individuals."

      Speaking of highs, it's a lot easier to make booze if you have agriculture.

I've always heard 90 days.

However, as the article says, it really depends on what habit we are trying to establish.

Maybe a placebo, but having this 21 days target did help me start habits in .. about 3 weeks.

One thing about habits is that you need to make room for them. And this can mean literal room or in a metaphorical sense. If you want to eat healthy for example consider that eating healthy literally starts before you eat, when you buy groceries. If you always go shopping for groceries when you're hungry, you're not gonna buy healthy stuff, and if you don't little healthy stuff at home you won't eat healthy.

>"If you’re trying a new diet, attempting to quit smoking or changing any daily routine, don’t expect new habits to be created in a week, or two or even three. Research suggests that the process requires 66 days (on average) and up to 8 months."

Something about the title suggested it was going to be much less than 21 days; maybe it's the domain name biasing my reading of the title.

  • 0xTJ 16 hours ago

    I agree that the title implies (or even declares) that it takes fewer than 21 days. I'd argue that the articles says that it does take those 21 days, plus many more, making the title deceptive.

    • lolinder 15 hours ago

      Exactly, English semantics dictate that if it takes more than 21 days it must first take 21 days.

      • cco 15 hours ago

        There is a very clearly implied only in the title. I agree that it should be included but it is unnecessary to convey the meaning imo.

        • crazygringo 15 hours ago

          There is not. I too assumed it must mean it takes less, otherwise there would be an "only", or "It takes more than".

          • girvo 14 hours ago

            I wonder what bias I have that made me read the title and assume "Huh, must be way longer" then?

          • kodt 14 hours ago

            I assumed it would take longer than 21 Days based on the title alone.

    • thih9 14 hours ago

      How I understood it, “form” here means that a habit has been formed.

      As in: “Habits aren’t formed in 21 days“, just like “Rome wasn’t built in one day”.

    Effort is usually quoted as a minimum ("It takes 20 minutes to drive there" "It costs $100 to buy this") which leads to a strange quirk that the negative is then interpreted as being a lower minimum, rather than a higher one ("It does not take 20min to drive there, "it does not cost $100 to buy this")

    • chimpanzee 14 hours ago

      Your examples make me wonder if the language of marketing has changed our assumptions about implied meanings where otherwise we'd recognize ambiguity.

      Or perhaps, marketing aside, it is just human nature to conjure implicit meaning rather than be confronted with ambiguity.

  • hansvm 14 hours ago

    There's a tendency sometimes to leave certain words implicit. "It does not [even] take 21 days to form a habit." Some of those linguistic habits never leave their birthplace, giving you colloquialisms like "do you want to come with [us]" in the Midwest. Most don't have any regional association though, and sentences with dropped fragments sound perfectly normal, with your mind filling in the gaps.

    In this case, the sentence is correct (though ambiguous) as written, but it has the same words you often see from a longer phrase with an omitted word implied through tone and other vocal cues, a pattern used commonly enough that I'd wager most people interpret it the same as you.

    • _dark_matter_ 13 hours ago

      "Do you want to come with" is a Midwest colloquialism?? Wow I say it all the time. Very weird to find out.

      • hansvm 12 hours ago

        It has Germanic roots too. Are any of the people you were close to growing up from the Midwest or from sort of Germanic or Scandinavian background?

    I have to think the research shows tighter distributions for some forms of habit?

  • voidhorse 16 hours ago

    Yeah same here. I think it's because (most of the time) headlines are optimized for sentiment. I would have expected a title like "It takes more than 21 days..." to indicate it takes more

    • rzk 15 hours ago

      But it doesn't necessarily take more than 21 days. According to the linked article, the average modeled time to plateau was 66 days, but the range was from 18 to 254 days.

I envy the neurotypicals who can just form habits, 21 days or otherwise.

People are neurotypical rarely if ever understand what those with ADHD go through. The best description I've heard is that people with ADHD don't have habits: we have trauma.

The meaning of that is that neurotypicals have the capacity to simply go into a rom and do something. It almost passively happens. ADHD people do not. Even getting up in the morning involves 50 questions being mentally asked and answered. Do I need to take something to the bathroom? Did I run the dishwasher? Did I leave the heating on? Do I need to do laundry today? And I'm 5 seconds into my day.

A brain that seeks novelty quickly gets bored with reptition. The only way you form habits is by the trauma of the consequences of not having that habit.

  • peterldowns 14 hours ago

    Funny, intentional routine / habit-formation has been the most effective way to help manage my ADHD. Sorry to hear that it's been impossible for you. For anyone else reading this, I would still recommend paying attention to your routine and seeing if you can help yourself by making adjustments.

    > It almost passively happens. ADHD people do not.

    I don't find this to be true for me or many other ADHD friends.

Trying to define any underlying logic would be to misunderstand what a habit is.
