PHQ | QUESTIONS: Basic Model For Incremental Personal Growth

Listen To The Podcast Episode: PHQ | QUESTIONS: Basic Model For Incremental Personal Growth

Personal growth has a branding problem.

We tend to imagine that meaningful transformation has to be dramatic. A retreat. A crisis. A life-changing book. A relationship ending. A career pivot. Some massive insight that reorganizes everything we thought we knew about ourselves.

And sometimes growth really does happen that way.

But most of the time?

Growth is considerably less cinematic.

Real personality development often looks like responding a little differently during an argument. Speaking up in the meeting where you usually stay quiet. Setting one boundary you would normally avoid. Asking one more question instead of assuming you already know the answer.

In other words, sometimes you don't need another paradigm shift.

You need a strategy.

In a Personality Hacker podcast Q&A, a listener named Steve asked how we can deliberately challenge ourselves beyond our comfortable personality patterns without needing an enormous life-altering experience.

It's a great question because personality type can tell us a lot about where growth needs to happen. But once we've identified that growth edge, we still need to know what to actually do about it.

That's where a practical model of personality development becomes valuable.

One remarkably simple strategy is this:

Ask yourself how you could become 5% or 10% better at one thing—and then practice that small improvement consistently.

Let's unpack why this works, how your personality type can help you choose where to begin, and how small changes can become meaningful long-term growth.

Personality Development Doesn't Mean Becoming a Different Personality Type

One of the most common misunderstandings about personal growth is the idea that maturity means becoming less like your type.

An Introvert needs to become an Extravert.

A Thinking type needs to become more Feeling.

An Intuitive needs to become more practical.

A Perceiving type needs to finally get organized.

But healthy personality development isn't about abandoning your natural wiring. It's about becoming more conscious, flexible, and skillful in how you use it.

That's an important distinction.

Your personality gives you certain mental processes that feel natural, comfortable, and easy to access. It also gives you processes that require more intentional development.

The goal isn't to replace your natural strengths.

It's to expand your range.

In the Personality Hacker Car Model, we describe the first four cognitive functions this way:

• Driver: your dominant cognitive function

• Copilot: your auxiliary cognitive function

• 10 Year Old: your tertiary cognitive function

• 3 Year Old: your inferior cognitive function

 

 

If you're beginning an intentional growth journey, we generally recommend focusing first on the Copilot.

Why?

Because your Driver is already doing a tremendous amount of work. It's the mental process you naturally trust and return to.

Your Copilot brings balance.

It asks you to engage life from a perspective that may feel less automatic but often creates greater adaptability, maturity, and psychological range.

This is one reason cognitive functions can make personal growth much more actionable. Instead of vaguely trying to “be better,” you can identify a specific mental process that deserves more conscious attention.

What's Your Copilot Cognitive Function?

Here's the Copilot process for each of the 16 personality types:

For example, an INTJ's Driver is Perspectives (Introverted Intuition). Seeing patterns, anticipating implications, and forming an internal vision of how things may unfold can feel natural.

Their Copilot is Effectiveness (Extraverted Thinking).

For an INTJ, personality development may therefore involve getting an idea out of the internal world and testing it against measurable reality.

What works?

What doesn't?

What resources are required?

What concrete step turns the vision into an outcome?

An INFP, by contrast, leads with Authenticity (Introverted Feeling) and develops greater balance through Exploration (Extraverted Intuition).

Their growth edge may involve getting outside an internal value assessment long enough to ask:

What else could be true?

What haven't I considered yet?

What happens if I experiment?

Neither person is trying to become another personality type.

They're expanding the range of their own.

That's a much healthier way to think about type-based growth. Personality development becomes less about correcting who you are and more about strengthening the parts of your personality that help you become more adaptable and conscious.

The 10% Better Personality Development Strategy

Once you know where you want to grow, the next question becomes much more practical:

How do you actually practice it?

Antonia shared an exercise originally suggested by a mentor:

“What could I do that would make me 10 percent more effective today?”

You can substitute almost anything for effective.

How could I be 10% more patient today?

How could I become 10% better at communicating what I need?

How could I be 10% more present with my partner?

How could I demonstrate 10% more courage?

How could I listen 10% better?

How could I practice my Copilot 10% more today?

The exact number isn't particularly important.

You're not expected to produce a spreadsheet proving you achieved precisely 9.87% more emotional availability on Tuesday.

The percentage is a metaphor for manageable expansion.

That's what makes this such a useful personality development practice.

You're asking yourself to move beyond your current comfort zone without launching yourself so far outside it that your nervous system immediately says, “Absolutely not.”

And if 10% feels overwhelming?

Make it 5%.

The important part is that the challenge is small enough to be repeatable.

Small Experiments Beat Heroic Effort

Imagine someone wants to become better at expressing appreciation in their relationship.

They could make the goal:

Become an incredibly loving and appreciative partner.

That's admirable.

It's also vague enough to be nearly useless.

The 10% question forces the goal into something actionable:

How could I express 10% more appreciation today?

Maybe the answer is:

“I'll tell my partner one specific thing I appreciated about them today.”

That's it.

But now something important has happened.

Personal growth has moved out of abstraction and into behavior.

And growth becomes much easier to sustain when it takes the form of concrete behaviors you can actually practice. This is where personality development becomes something you live rather than merely something you understand intellectually.

Tomorrow, maybe the question produces another answer.

Listen without looking at your phone.

Ask how their day actually felt instead of merely asking how it went.

Offer affection without waiting for them to initiate.

Thank them for something that's become so routine you normally overlook it.

None of these actions will transform a relationship overnight.

That's precisely the point.

You're building a trajectory.

Use Your Personality Type to Define What “Better” Means

Different personality types may naturally approach the 10% experiment differently.

If you're leaning on Accuracy (Introverted Thinking), you may enjoy defining what improvement actually means. What variables are involved? What would make this skill more precise? What could you observe?

If you're using Effectiveness (Extraverted Thinking), you may naturally look for results. What action produced the best outcome? What is working? How could the process become more efficient?

With Authenticity (Introverted Feeling), the question may become more personal. What would feel more aligned with the person I want to be? What action would represent my values more honestly?

And with Harmony (Extraverted Feeling), you might pay attention to relational impact. What creates greater connection? What response helps the other person feel understood? What would improve the emotional dynamic?

The strategy doesn't have to look identical for everyone.

In fact, effective personality development shouldn't look identical for everyone.

The important thing is that the process produces conscious experimentation instead of simply repeating whatever comes most naturally.

Start Your Personality Development Practice With a Question

There's another part of this practice that may be even more important than measuring your progress.

Joel puts it this way:

“The important thing to take away from this is the question even more than the tracking of the results.”

That's a deceptively powerful insight.

When you repeatedly ask yourself a specific question, you give your attention somewhere to go.

Suppose every morning you ask:

How could I feel 10% more empowered today?

You may begin noticing choices you would otherwise ignore.

Maybe empowerment means sending an email you've been avoiding.

Maybe it's saying no.

Maybe it's exercising.

Maybe it's asking for help instead of struggling silently.

Maybe it's deciding that someone else's disappointment doesn't automatically mean you've made the wrong decision.

The question creates a frame through which you start noticing opportunities.

You don't have to know the perfect answer beforehand.

In fact, that's part of the experiment.

Personal growth is often less about already knowing what to do and more about becoming willing to test new ways of responding.

A Simple Daily Personality Development Practice

Choose one area of your life you want to improve.

Not six.

Not your relationship, career, health, finances, communication skills, meditation practice, morning routine, and unresolved childhood issues simultaneously.

One thing.

Then try this:

At night: Write down your question.

How could I become 10% better at ______ tomorrow?

In the morning: Read it again.

Don't demand a profound answer. Just allow one or two small actions to emerge.

During the day: Run the experiment.

Notice what happens.

That evening: Ask three questions:

• What did I try?

• What happened?

• What is one small adjustment I could make tomorrow?

Then repeat.

As Antonia says in the episode:

“Pick one aspect of your life at a time.”

Focusing on one area gives your attention somewhere specific to organize itself.

If you're trying to improve everything simultaneously, almost nothing gets enough deliberate attention to change.

Good development is usually less about intensity and more about sustained focus.

Make the Practice About Your Copilot

This process becomes especially useful when applied directly to your cognitive-function development.

Instead of vaguely deciding to “work on your Copilot,” identify what using that function would actually look like in your life.

An INFJ developing Harmony (Extraverted Feeling) might ask:

How can I communicate 10% more of what's happening inside me instead of assuming people will understand?

An ENFP developing Authenticity (Introverted Feeling) might ask:

How can I spend 10% more time checking what I genuinely value before saying yes to another possibility?

An ISTP developing Sensation (Extraverted Sensing) might ask:

How can I engage 10% more directly with what's happening around me instead of remaining inside my analysis?

An ESFJ developing Memory (Introverted Sensing) might ask:

How can I slow down and reference 10% more of my own past experience before responding to everyone else's immediate needs?

An ENTJ developing Perspectives (Introverted Intuition) might ask:

How could I spend 10% more time considering the long-range implications before moving directly into execution?

These are small interventions.

But practiced repeatedly, they can increase conscious access to a process that previously appeared mainly when circumstances demanded it.

That's where type theory stops being merely intellectual and starts becoming behavioral.

Personality Development Should Stretch You, Not Overwhelm You

There's a popular idea that growth happens “outside your comfort zone.”

True enough.

But that phrase can tempt us into thinking that the farther outside our comfort zone we go, the more growth we're accomplishing.

That's not necessarily useful.

The goal isn't to constantly overwhelm yourself.

The goal is to expand your capacity.

If you're terrified of public speaking, committing tomorrow to deliver a keynote to 2,000 people probably isn't a useful next step.

Speaking for two minutes during a team meeting might be.

If you've spent years avoiding conflict, announcing every unresolved grievance you've accumulated since 2014 over dinner tonight isn't necessarily courageous growth.

Clearly communicating one boundary might be.

Ask yourself:

What is slightly uncomfortable but genuinely doable?

That is often where the next useful experiment lives.

What About the “21 Days to Form a Habit” Rule?

In the original conversation, Joel and Antonia reference the popular idea that it takes 21 days to create or break a habit.

Twenty-one days can certainly be a useful practice sprint, but habit formation doesn't operate on a universal 21-day deadline.

People vary dramatically in how long it takes for a new behavior to become automatic.

So don't treat Day 21 as a pass/fail test.

A better approach is to use 21 days as an initial experiment, then continue for 30, 60, or more days if the behavior still requires conscious attention.

This fits the larger growth principle beautifully:

Stay with one area long enough to notice change.

Consistency matters more than hitting a magical number of days.

Don't Confuse Incremental Growth With Staying Small

There's an understandable objection to all of this.

If I'm only trying to get 5% or 10% better, aren't I playing it safe?

Not necessarily.

Small actions can compound into very different lives.

The person who practices one difficult conversation at a time eventually becomes someone capable of having difficult conversations.

The person who repeatedly experiments with their Copilot becomes more psychologically flexible.

The person who asks every day, What would make this slightly better? develops a relationship with growth that doesn't require waiting for motivation, crisis, inspiration, or another personality book.

That's a very different way of living.

Big insights can change your trajectory.

Small practices determine whether you actually travel down the new road.

That is one of the central principles of sustainable personal growth.

A Practical Model for Personality Development

If you want to put the entire idea into one framework, it looks like this:

1. Know your personality type. Understand your natural cognitive-function preferences rather than treating personal growth as generic self-improvement.

2. Identify your Copilot. Your auxiliary cognitive function is an important early target for personality development because it expands your range beyond habitual Driver strategies.

3. Choose one area of life. Relationships, leadership, communication, health, creativity—pick the area where growth would matter most right now.

4. Ask the 5% or 10% question. Make the next step small enough to be actionable.

5. Run an experiment. Convert the answer into behavior today.

6. Review what happened. Keep what works. Adjust what doesn't.

7. Repeat long enough to see a pattern. Don't abandon the practice simply because transformation isn't instantaneous.

That's incremental growth.

Not flashy.

Not particularly glamorous.

But remarkably powerful.

The Bigger Goal of Personality Development: Becoming More Conscious

Personality type isn't useful because it gives us another identity to protect.

It's useful because it gives us a map.

A map of what we naturally notice.

What we instinctively trust.

Where we tend to over-rely on familiar strategies.

And where greater consciousness may be asking us to grow.

Your personality type doesn't have to become your limitation.

It can become the starting point for intentional development.

And sometimes that development doesn't begin with an earth-shattering realization.

Sometimes it begins tonight, with a notebook and a simple question:

What could I do tomorrow that would make this part of my life 10% better?

Write down your answer.

Try it.

And then ask again tomorrow.

Key Takeaways

• Personality development doesn't require becoming a different personality type; it means developing greater flexibility within your existing type structure.

• In Personality Hacker's Car Model, the Copilot, or auxiliary cognitive function, is an important early focus for intentional growth.

• Instead of demanding dramatic transformation, ask how you could improve one area by just 5% or 10%.

• Translate self-knowledge into a specific behavior you can experiment with today.

• Focus on one growth goal at a time rather than trying to overhaul your entire life.

• Habit formation doesn't happen according to one universal timetable, so prioritize consistency over an arbitrary deadline.

• Repeated questions, experiments, and reflection can turn abstract self-knowledge into sustainable personal growth.

Sometimes meaningful personality development begins with one small question:

What could I do today that would make this part of my life 10% better?

If you want to better understand your unique personality, identify the growth path built into your type, and intentionally develop your Copilot cognitive function, explore the Personality Owners Manual. It gives you a practical framework for turning personality awareness into consistent, meaningful personal growth.

You don't need to reinvent yourself overnight.
