Sometimes changing the behavior is how you change the belief.
Nearly 300 years ago, Benjamin Franklin decided he wanted to become a better man.
He didn’t simply write down the kind of person he hoped to become. He didn’t repeat affirmations about his character or wait until he felt sufficiently disciplined, virtuous, or motivated to behave differently.
He built a system.
Franklin identified thirteen virtues he wanted to develop, including temperance, order, resolution, industry, sincerity, justice, moderation, tranquility, and humility. Then he made a small book to keep track of how well he was actually living them.
I’ve written more about Benjamin Franklin’s remarkable self-improvement system here, including how he used his thirteen virtues as a practical framework for changing his behavior.
The method was remarkably practical. His chart contained the thirteen virtues and the seven days of the week. Each evening, Franklin examined his behavior and placed a small mark beside a virtue when he believed he had fallen short.
But perhaps the most interesting part was that he didn’t try to perfect all thirteen virtues at once.
He concentrated particularly on one virtue for a week before moving to the next. Thirteen virtues meant a thirteen-week cycle, which he could repeat several times over the course of a year.
Franklin was doing something that feels surprisingly modern.
He was turning intention into behavior and behavior into visible evidence.
What Franklin Understood About Change
Franklin could have created a list describing the person he wanted to be and stopped there.
Instead, he created a practice.
There is an important difference.
We often talk about identity as though it must come first. Decide who you want to become. Believe that you are that person. Then behave accordingly.
There is value in that approach. Identity can certainly influence behavior. Someone who genuinely thinks of himself as a runner, writer, saver, entrepreneur, or healthy person may find certain choices easier because those choices are consistent with the person he believes himself to be.
But what happens when you don’t believe it yet?
What happens when years of experience seem to provide evidence for the opposite?
Telling yourself, I am disciplined, may not carry much weight when your recent history seems to say otherwise.
This is where Franklin’s little book becomes interesting.
He didn’t need to wait until he believed he possessed a virtue before practicing it.
He practiced the behavior first.
And every day gave him another piece of information.
Modern Research Is Looking at Something Similar
A 2026 eight-week behavior-change study involving 89 adults measured several outcomes, including exercise habit strength and exercise identity. By the end of the intervention, researchers reported significant increases in both.
That doesn’t prove that practicing a behavior automatically changes identity. The study did not include a control group, which means we should be careful about claiming cause and effect.
But the finding fits an increasingly useful way of thinking about behavior change.
Identity and behavior don’t necessarily operate in only one direction.
Your identity can influence your actions.
But your actions can also provide evidence that influences your identity.
That distinction matters enormously for someone trying to change.
If you believe you must first become motivated, confident, disciplined, or convinced before you can act, you can spend a very long time waiting for your internal world to change.
There is another possibility.
Begin before you believe.
Take the action first and allow the evidence to accumulate.
Action Creates Evidence
Imagine someone who has spent years saying, “I can never stick with exercise.”
There is probably evidence behind that belief. Maybe they’ve joined gyms and stopped going. Started walking programs and abandoned them. Bought equipment that eventually collected dust.
Simply replacing the old statement with I am someone who exercises consistently may feel artificial because the person’s experience hasn’t caught up with the words.
Momentum Mastery approaches the problem differently.
Don’t begin by demanding a new identity.
Begin by creating a piece of evidence.
Walk for ten minutes.
Tomorrow, do it again.
On the difficult day, use the Floor Rule and walk for two minutes rather than disappearing completely.
Put a mark on the calendar.
Now there is evidence.
One walk doesn’t make someone a lifelong exerciser. Neither do three walks or perhaps even thirty. But something important is beginning to happen.
The old belief—I never stick with anything—no longer has the entire evidence file to itself.
There is now contradictory evidence.
I said I would walk today, and I walked.
Then:
I said I would do it again, and I did.
Eventually:
Maybe I can actually do this.
And later:
This is becoming something I do.
The identity doesn’t have to be manufactured. It can be earned through evidence.
Franklin Made His Evidence Visible
This may be the part of Franklin’s experiment that I find most interesting.
He didn’t leave the process entirely inside his head.
He made it visible.
His little chart showed him what had happened. The marks gave him feedback. Over time, he hoped to see fewer of them.
He could observe his behavior rather than relying entirely on his memory or his intentions.
That principle remains useful today.
We tend to underestimate small actions partly because we forget them. A ten-minute walk doesn’t feel significant. Reading five pages doesn’t feel significant. Saving a small amount of money doesn’t feel significant. Writing for fifteen minutes doesn’t feel significant.
Viewed individually, they aren’t dramatic.
But make them visible and something changes.
You begin seeing a pattern.
And patterns tell a different story than isolated actions.
This is why visible progress matters so much in Momentum Mastery. A tracker, calendar, notebook, checklist, journal, or simple series of checkmarks isn’t merely recording what you did.
It is preserving evidence.
Evidence that you showed up.
Evidence that you continued.
Evidence that you kept a promise to yourself.
Franklin Wasn’t Perfect Either
There is another reason I like Franklin’s story.
His system didn’t turn him into the flawless person he originally imagined becoming.
He admitted that some virtues were much harder for him than others. Order, in particular, gave him trouble. He discovered that changing himself was considerably harder than designing a chart for changing himself.
That may be the most reassuring part of the entire experiment.
The value wasn’t perfection.
The value was practice.
Franklin believed he became better because he attempted the process, even though he never achieved the spotless record he originally envisioned.
That sounds a great deal like Momentum Mastery.
The objective isn’t to produce an uninterrupted record proving that you never struggle.
The objective is to create enough repeated evidence that struggle no longer automatically returns you to zero.
Behavior and Identity Can Build Each Other
Eventually, something interesting can happen.
At first, identity may help produce action:
I want to become someone who takes care of his health.
Then action begins producing evidence:
I exercised today.
Repeated evidence begins influencing belief:
I’m proving that I can keep doing this.
Belief begins strengthening identity:
I’m becoming someone who exercises consistently.
And the stronger identity makes the next action a little more natural.
The process begins feeding itself.
Action → Evidence → Belief → Identity → Easier Action → More Evidence
That’s momentum.
You aren’t merely repeating a behavior. You’re gradually changing the story your own experience allows you to tell about yourself.
Don’t Wait for the New You
There is a temptation in personal development to wait for an internal transformation before beginning the external work.
I’ll start when I’m motivated.
I’ll speak up when I’m confident.
I’ll write when I feel like a writer.
I’ll exercise when I become disciplined.
I’ll make the decision when I’m certain.
But perhaps Benjamin Franklin stumbled onto something nearly three centuries ago that remains useful today.
You don’t always have to feel like the person first.
Sometimes you practice being that person.
Choose something small enough to repeat. Make the behavior visible. Pay attention to what happens. Continue long enough to accumulate evidence.
Then allow the evidence to speak.
Instead of repeatedly telling yourself:
I can do this.
Take one reasonable action.
Then another.
And eventually you get to say something much more powerful:
I just proved it.
You don’t always have to change the belief before you change the behavior.
Sometimes changing the behavior is how you change the belief.
And sometimes the person you’re trying to become isn’t waiting somewhere in the future.
You’re building that person with what you do today.
