Which is better when it comes to building habits? Taking an incremental approach or going all-in for a while? Today I’m comparing two approaches from the books Atomic Habits and Unhinged Habits. I’ll share the pros and cons for each one, and the biggest mistake I see people make that undermines progress. Plus, I’m sharing how I’m approaching my own experiment based on this information.

Speaker:

When my friend posted about a book I was considering reading, her review

Speaker:

was short and simple. And as soon as she said

Speaker:

Opposite of James Clear, my curiosity was

Speaker:

piqued. Now I'm talking about the book Unhinged Habits

Speaker:

by Jonathan Goodman. And as a fan of the

Speaker:

bestselling Atomic Habits by James Clear, I had to

Speaker:

know what my friend meant when she said this

Speaker:

is the opposite. So today I am discussing ideas

Speaker:

from these two books. How do they differ on this idea of

Speaker:

transformation and habits? And what are the

Speaker:

approaches that they take because they are in opposition to each

Speaker:

other, even though there are some things they have in common. Now, I will also

Speaker:

share about where I fall on this spectrum and

Speaker:

where I have gotten it wrong in the past and also seen

Speaker:

a other people get it wrong. So let's start with the core

Speaker:

ideas in these books that oppose each

Speaker:

other. Now, Atomic Habits. This one is about making

Speaker:

consistent incremental improvements that compound

Speaker:

over time. And I've got this picture that I took from

Speaker:

James Clear. This is from his website. And it's this idea that

Speaker:

making these tiny consistent incremental

Speaker:

improvements compound over time, just like a bank account.

Speaker:

Now what he says here is that over time, Even if it's

Speaker:

1% per day, eventually it'll be

Speaker:

37% by the end of, I think it's a year.

Speaker:

Now I'm going to read a quote from the book. I've got a

Speaker:

little. Got a little sticky here. And actually

Speaker:

two, I've got two quotes. So the first one, improving

Speaker:

by 1% isn't particularly notable. Sometimes it

Speaker:

isn't even noticeable. But it can be far more

Speaker:

meaningful, especially in the long run. The difference a

Speaker:

tiny improvement can make over time is astounding. And then

Speaker:

he goes on to say, people sometimes make a

Speaker:

few small changes. They fail to see a tangible result and they

Speaker:

decide to stop. They think, I've been running every different month,

Speaker:

so why can't I see any change in my body? Once this thinking

Speaker:

has taken over, it's easy to let good habits fall by the

Speaker:

wayside. But in order to make a meaningful, different habits

Speaker:

need to persist long enough to break through this plateau.

Speaker:

And he calls it the plateau of latent potential. Essentially

Speaker:

because this is a curve that starts out really slow, but then it

Speaker:

starts to really lift. This is where a lot of people will say, I'm just

Speaker:

not seeing these improvements. And so they give up. And I'm sure

Speaker:

that many of us are familiar, I know I have experienced

Speaker:

that, where it just doesn't feel like enough.

Speaker:

Now what is the difference when it comes to

Speaker:

Unhinged Habits. And what is this author saying?

Speaker:

So I don't have a picture, but I am going to read a couple of

Speaker:

quotes. So in Unhinged Habits,

Speaker:

there's a particular chapter called Define youe Season. It says, this chapter

Speaker:

offers a radical, almost unhinged alternative

Speaker:

to the myth of balanced improvement. A seasonal approach where

Speaker:

focused intensity on one priority replaces scattered

Speaker:

consistency across many. By embracing intense

Speaker:

seasons of growth followed by periods of rest or maintenance, you'll make

Speaker:

transformative progress in what matters most while keeping the guilt at bay.

Speaker:

This isn't about doing more, it's about doing less with

Speaker:

greater intensity at the right time.

Speaker:

Now, the other quote that I think is important to mention

Speaker:

in this, in this context is that he's essentially

Speaker:

looking at consistency versus intensity. However,

Speaker:

Unhinged Habits still references consistency. And

Speaker:

the author says consistency is undeniably important,

Speaker:

but it needs to flank periods of intensity stacked atop one

Speaker:

another. Focused on one aspect of your life you want to

Speaker:

measurably improve. And in the book,

Speaker:

just like in Atomic Habits, there's the example of running. Well, I'm running every day,

Speaker:

but I'm not seeing anything in this book. The author,

Speaker:

Jonathan, was a personal trainer, and so he does use the

Speaker:

example of a transformation for your health. That for

Speaker:

many people taking a period of intensity, say eight to 12

Speaker:

weeks, really committing to a program and

Speaker:

focusing on that, you will see faster improvements than if you say you

Speaker:

started going to the gym twice a week, which is something maybe you want to

Speaker:

do for the rest of your life. But if you just do that, you don't

Speaker:

see them quickly. So we talked about that. Now this idea is that

Speaker:

in the gym or with health, when somebody starts to

Speaker:

see transformation early, that can

Speaker:

actually be extremely motivating. Now, there's one other quote

Speaker:

that I think is really important to mention in this book. And I don't think

Speaker:

you'll be surprised that it stood out to me. And this is the author

Speaker:

being brutally honest, saying, for better or

Speaker:

for worse, my human brain craves novelty and excitement

Speaker:

and immediate gratification. Maybe I'm not strong willed enough

Speaker:

to overcome thousands of years of evolutionary physiology.

Speaker:

Maybe my mind is naturally weaker than others. If so, it is what

Speaker:

it is, right? Regardless, it's up to me to work with the

Speaker:

physiology that I've got. It's probably no surprise

Speaker:

that that is a quote that would stand out to me because I

Speaker:

do think how we're wired matters. And even if you

Speaker:

are someone, when you read different books by different authors, you can get A pretty

Speaker:

good sense that their style

Speaker:

lends itself to the book they're writing. This is how they operate,

Speaker:

it works for them. So they write a book and they share with other people

Speaker:

how that works. In essence, this is

Speaker:

personal. There's a very good chance you have tried both. I

Speaker:

know I have. I've tried the consistency, I've tried the intensity.

Speaker:

And I think there is room for both.

Speaker:

But there's also a very good chance that you have a preference.

Speaker:

And I don't think you should feel judged if

Speaker:

one way works better than you or the other. And it's not necessarily

Speaker:

an either or. And there might be things in your life for which this intensity

Speaker:

followed by consistency might work really well for you.

Speaker:

And then there are other areas of your life where actually just straight up consistency

Speaker:

is gonna work. Now what I wanna do is let's look at some of the

Speaker:

pros for both of them. So an

Speaker:

advantage to atomic habits is that you focus on

Speaker:

establishing it's a sustainable practice. Or

Speaker:

as James Clear likes to talk about, it's a system. And that can

Speaker:

last over the long haul. So it's sort of this idea of start the way

Speaker:

you want to finish. And let's use the example of going to the gym

Speaker:

twice a week. So if you can make it twice a week over the long

Speaker:

haul, you'll probably be healthier than someone who just shows up to the gym for

Speaker:

a few months, then stops for six months, et cetera. So having something that is

Speaker:

sustainable over the long haul is great. And because the

Speaker:

atomic habits focus on having these systems in place

Speaker:

that you can repeat over, over a long period, it does mean you

Speaker:

can focus on multiple habits at one time and sort of

Speaker:

build them in a way where they fit into your life and then you

Speaker:

can continue on fitting them into your life. Now, an

Speaker:

advantage or a pro to the unhinged approach is that you do

Speaker:

see progress faster, which can be very motivating

Speaker:

for people. And the emphasis on this

Speaker:

transformation through this intense season of your life

Speaker:

and then flipping to maintain, that can be an

Speaker:

effective way to keep up what you've gained. So with the gym example,

Speaker:

if you do gain strength or increase your muscle mass,

Speaker:

change your body composition, then later you can go into

Speaker:

more of that consistent, maintain phase. And it doesn't require the same

Speaker:

level of intensity. As long as you continue with your

Speaker:

good habits now consistent, there are some

Speaker:

disadvantages. So atomic habits, we already talked about this idea that sometimes you aren't seeing

Speaker:

results and you start to question the effort. Is this worth

Speaker:

it? I Don't see any payoff. And sometimes with this

Speaker:

incremental approach, if you are not going all

Speaker:

in, it might feel like you're not really committing or giving it the

Speaker:

attention that you think it needs in this moment. And so it also might

Speaker:

play with some mindset things around is this even really a priority?

Speaker:

Now? A con for the unhinged habit is that it does,

Speaker:

as he said, focus on this and do less

Speaker:

of the other things. So you need to deprioritize other

Speaker:

practices in your life during that season and you

Speaker:

might start to resent maybe how much time it's taking. If you

Speaker:

are really, really, really zeroing in on this and this is the season, it's taking

Speaker:

up a lot of your time, you might start to hate that you're saying no

Speaker:

to other opportunities as a trade off for this period of intensity.

Speaker:

The other thing is that you have a high risk of, let's call

Speaker:

it a post intensity drop off, which is a

Speaker:

mistake that I know very well and it's a mistake that I've seen a lot

Speaker:

of other people make with these periods of intensity.

Speaker:

Now, in case you couldn't guess, I am a person who naturally

Speaker:

gravitates to go sort of all in. I love a grand

Speaker:

plan. I usually like to name my plants. I love this

Speaker:

focus. And maybe it's hyper fixation, but in

Speaker:

many cases I do experience a transformation from

Speaker:

these seasons of intensity in my life. They can be very

Speaker:

fulfilling and I can get really into it. But there

Speaker:

is a big but it can come with this risk which is the

Speaker:

maintain. It's that part where you're staying consistent afterwards.

Speaker:

And that is where I am naturally wired to kind of get into

Speaker:

the really intense. I like this. This is novel, this is exc. But

Speaker:

then when it becomes, dare I say, boring or that

Speaker:

maintenance phase, it just doesn't thrill me and it's a little bit harder to keep

Speaker:

up. I get so focused also on the plan for

Speaker:

the intense period that I don't spend any time

Speaker:

coming up with an off ramp. And this is something

Speaker:

that you need in order to ease yourself back into consistent

Speaker:

practices so you don't lose everything that you built

Speaker:

towards during that. Now, I'll use a personal example

Speaker:

for both me, but also as a practitioner. So over

Speaker:

the years, because of chronic health and autoimmune diseases,

Speaker:

I have played around with my diet. I've done a lot of

Speaker:

elimination diets, which I have learned so much, a tremendous amount

Speaker:

about what works for me and what maybe deters against my

Speaker:

health. And during Those periods, I was full

Speaker:

on. I was all in, full, full on. But as soon as those periods

Speaker:

were over, because I hadn't come up with an off ramp of

Speaker:

what does this look like long term? What does this look like sustainably? Everything

Speaker:

kind of crumbles and falls apart. And that is where

Speaker:

I tend to go wrong. But also, I worked in nutrition, I was a practitioner,

Speaker:

I had my own clinic and or I was part of a

Speaker:

clinic. And when I was seeing clients for nutrition,

Speaker:

the same thing would happen to them if we didn't come up with a plan.

Speaker:

And the other thing is if it's something like an elimination diet, which can be

Speaker:

used therapeutically of learning what works with your

Speaker:

body and what doesn't, pulling out all those foods as soon

Speaker:

as that intense period is done, a lot of people feel like, okay, now

Speaker:

I'm just gonna just have all the things I've been missing. So without

Speaker:

that off ramp, you can undo or hinder or harm

Speaker:

what you have spent all of this time and effort on. Now I

Speaker:

truly believe that either option can work.

Speaker:

And really what they have in common is they both require

Speaker:

intention. You need to know what your outcome is. You need

Speaker:

to think about what you need to do and what your goals are, what

Speaker:

are you actually aiming for, and whether you go with a more

Speaker:

consistent, more consistency approach, the atomic

Speaker:

habits style, or a more seasonal

Speaker:

intensity and then consistency approach, both cases

Speaker:

you can apply the momentum formula. And one of

Speaker:

the things, I bring this up because it's something I am thinking about in

Speaker:

my life right now after reading this book. It got me reflecting a lot on

Speaker:

what has worked, what hasn't worked, and what has the

Speaker:

potential for me, but also needs work. And I bring this up because

Speaker:

when it comes to creating a plan, whether that's just straight up

Speaker:

consistency going atomic habits or whether that's going

Speaker:

for intensity followed by consistency, in both cases

Speaker:

you need to think practically. So, so what is the actual method? What am

Speaker:

I doing? What's my system? I know Atomic Habits talks a lot about

Speaker:

systems, so what are the things I need to do in order to improve?

Speaker:

Whether it's 1% or whether it's intense, but

Speaker:

also thinking about how do I make this personal? And that's where

Speaker:

mode comes in. How do I have this work for me? And

Speaker:

we took that quote, or I read you that quote from Unhinged Habits around

Speaker:

this is what works for my brain. I think that's really

Speaker:

important, but not just during the intensity, but also afterwards,

Speaker:

what is going to suit me long term. I know that Sometimes I struggle

Speaker:

with boredom if it's just a maintaining thing that can get dry.

Speaker:

So how do I incorporate an off ramp, a plan for maintaining

Speaker:

that also includes something that personally suits me

Speaker:

and also mindset. Mindset is so important and for this we can think about what's

Speaker:

the perspective I need for whatever it is I'm doing.

Speaker:

So if we are taking an incremental approach, what is the perspective

Speaker:

so that I stick with this even when I'm not seeing

Speaker:

progress right away? How do I handle any doubts

Speaker:

that creep up so I don't self sabotage? Now, if you are

Speaker:

going for a more intense period, you might have to say, how do

Speaker:

I take a perspective or mindset where I don't feel

Speaker:

like I'm resenting the other things that I'm letting go of during this period and

Speaker:

I'm intentionally choosing this season and, and this is something, a choice I'm

Speaker:

making instead of taking on a mindset where you feel like you're missing out

Speaker:

on all these things that make you want to jump off and say enough of

Speaker:

this. And then for that off ramp, what's the mindset of how do I

Speaker:

transition so that I am not self

Speaker:

sabotaging on the back end? What's the story I'm

Speaker:

telling myself when it comes to maintaining these improvements that

Speaker:

I've made and what does the next season look like because you don't want to

Speaker:

let go of everything that you've built. And a lot of this is really important

Speaker:

mindset work. And if we take that example for nutrition, the number

Speaker:

of people who had this kind of all or nothing, I am on the plan,

Speaker:

it's intense or I'm off and then everything falls,

Speaker:

falls apart and crumbles. And then people end up feeling like garbage within a few

Speaker:

weeks. So we don't want to swing so wildly. We want to

Speaker:

think about that off ramp. Now, for me personally,

Speaker:

I am going to be approaching a season, an

Speaker:

intentional season of intensity. And I

Speaker:

say that with quotes because the

Speaker:

experiment for myself is actually around

Speaker:

my rehabilitation for some injuries related to

Speaker:

hypermobility. I've shared it before, but in

Speaker:

the fall I was diagnosed with hsd, which is hypermobility

Speaker:

syndrome disorder. And it is where a

Speaker:

deficiency in connective tissue causes a lot of injuries, but it also causes

Speaker:

other problems with different organs in my body. And, and this can make

Speaker:

it really difficult. And I've worked with a lot of practitioners, many who are just

Speaker:

not very familiar with how to deal with HSD or

Speaker:

the other one, Ehlers Danlos syndrome, or eds. They're

Speaker:

very, they're very linked. And what I have done is

Speaker:

actually registered for a program that is specifically

Speaker:

designed for people with HSD and eds,

Speaker:

and I will be going through that program. Now, the thing about the program, the

Speaker:

reason I say intensity, is that these

Speaker:

programs are deliberately low and slow

Speaker:

because of the chance of injury. Now, I

Speaker:

have decided though, that there are other habits or

Speaker:

practices or hobbies that I enjoy, but I'm going to

Speaker:

kind of ease off a little bit on those in order to really dedicate

Speaker:

time to making this a priority. Because I know if I can build that

Speaker:

foundation and really zero in on that, then I can start to

Speaker:

reduce the chance of injury. If I were say, to take more

Speaker:

of the 1% incremental approach, then

Speaker:

I just might not be able to get to the place I want to be

Speaker:

in the same time period. So I really am motivated by this idea of

Speaker:

that transformation, especially if it means that I can start to

Speaker:

reduce the chance of injury. And this means saying no

Speaker:

to other things and just not feeling guilty about it because I'm

Speaker:

intentionally choosing the season. However, there are

Speaker:

two plans that are required. One is during this season of

Speaker:

intensity. So for me, over the next two months. So as I

Speaker:

record this, this is. We're just starting April. It's April and May.

Speaker:

And I have told the people close to me that I am doing this

Speaker:

so that I can set expectations and I can start to make decisions

Speaker:

that say, yes, this is something I'm focusing on and I can say no

Speaker:

to some of the things that might get in the way of that.

Speaker:

But I need a second plan which is my off ramp and that is

Speaker:

really paying attention over the next two months. How do I keep this

Speaker:

consistently? How do I maintain the progress that I've experienced

Speaker:

and what does this look like on the maintain on the back end

Speaker:

where it's a part of my regular routine, but it's just not as intense.

Speaker:

And like the example with fitness,

Speaker:

once you have built up a certain level, then it is easier to

Speaker:

maintain because you've kind of built up that. That foundation. And so that's something

Speaker:

that I really looking to do. But I'm going in with

Speaker:

this mindset that I need to have a plan

Speaker:

and it needs to be personalized to me and I need to have

Speaker:

that good perspective around what does this look like

Speaker:

both during. What's my mindset during the intensity, but also what is

Speaker:

my mindset after the fact so that I can maintain it. Both

Speaker:

require that intentionality and that is something that I'm looking to

Speaker:

do. Because really regardless whether you go

Speaker:

consistent all the way atomic habits or whether you

Speaker:

choose something that's more intense seasons followed by those

Speaker:

periods of consistency, both of them need intention, but

Speaker:

both of them you can have momentum and keep it.
