Know Thyself: The Ancient Wisdom That Turned Me into a Leader (Even Though I Never Wanted to Be One)

How a 2,500-Year-Old Doctor Pulled Me Out of My Shell

Most people know Hippocrates as the father of medicine—best remembered for the phrase,

But that wasn’t the quote that changed my life.

What did?

Two simple words: Know Thyself.​

It wasn’t a motivational line to me.

It was a wake-up call.

See, I never set out to be a leader.

I didn’t crave attention. I wasn’t the guy raising his hand or shouting out orders.

I was the quiet one—head down, work done.

Analyzer first, Driver second.

I liked solving problems.

I liked getting things right.

But time and time again, I found myself thrust into leadership positions.

Not because I asked for them.

But because no one else stepped up, a classic example of a "leadership vacuum."​

And in those moments of silence, when the room was confused or the job site was crumbling, I could feel that pull:

It wasn’t easy at first.

Leading meant managing people—and people, to be blunt, are messy.

• Confusing.
• Emotional.
• Inconsistent.

That’s when Hippocrates stepped back into my life.

Not through medicine, but through psychology—his model of the Four Temperaments.

Unlike astrology or those slick personality quizzes that go viral for a week and disappear, this model worked.

It helped me understand myself.

It helped me understand others.

And eventually, it helped me build the kind of leadership I now teach at The Leader’s Dojo.​

Not command-and-control.

Not charisma-first.

But a quiet, deliberate, deeply personalized form of leadership that starts with one thing:

Why Most Men Struggle to Lead (Even If They’re Smart, Capable, and Hardworking)

If you’re a young man in your 20s or 30s, you’ve probably felt this:

You know you’re capable of more.

But you keep hitting walls:

• People don’t listen.
• Teams fall apart.
• You doubt your decisions.
• You don’t know who to trust—or how to communicate.
• And worst of all… you start wondering if you’re the problem.

You’re not.

You’re just missing a framework.

You don’t rise to the level of your ambition.

That’s where Hippocrates’ model comes in.

The Four Temperaments:
A Warrior’s Personality Compass

Most modern systems overcomplicate personality.

But the Four Temperaments cut through the noise with surgical simplicity.

Hippocrates believed each person had a dominant humour—a core temperament—that shaped how they thought, spoke, acted, and reacted.

Today, we’ve mapped that to a clean 2x2 matrix along two powerful axes:

• Horizontal axis: People-Oriented ↔ Information-Oriented
• Vertical axis: Fast-Talker/Doer ↔ Slow Listener/Thinker

Drop those into quadrants, and you get this:

Everyone has all four in them, but one usually dominates.

A second temperament shows up under stress or pressure.

The third and fourth express themselves when triggered by specific circumstances.

And here’s the kicker:

Let me show you how.

What Each Temperament Values, Fears, and Needs

🔥 Driver (Faster, Task-Oriented)

• Core Drive: Winning, Results, Impact
• Big Fear: Losing, Weakness, Wasting Time
• Strengths: Gets shit done, leads from the front
• Blind Spot: Doesn’t listen well, rushes people, burns bridges

🔍 Analyzer (Slower, Task-Oriented)

• Core Drive: Accuracy, Understanding, Control
• Big Fear: Being wrong, chaos, failure
• Strengths: Detailed, logical, plans deeply
• Blind Spot: Overthinks, avoids confrontation, analysis paralysis

🎤 Promoter (Faster, People-Oriented)

• Core Drive: Recognition, Fun, Influence
• Big Fear: Rejection, Being Ignored, Boredom
• Strengths: Natural connector, persuasive, optimistic
• Blind Spot: Scattered focus, avoids accountability, overpromises

🤝 Supporter (Slower, People-Oriented)

• Core Drive: Peace, Belonging, Stability
• Big Fear: Conflict, Change, Letting People Down
• Strengths: Loyal, empathetic, steady
• Blind Spot: Avoids decisions, passive under stress, internalizes problems

The Leadership Advantage of Knowing the Grid

Let’s say you’re building a team.

You don’t want to guess who belongs where.

You want to know. And more importantly, you want to place people where they shine.

Here’s how you use it:

✅ Need a reliable technician?

Hire an Analyzer/Supporter. They’ll do it right, check it twice, and take pride in helping others.

✅ Need a visionary leader to push a product or campaign?

Find a Driver/Promoter. They’ll charge forward and bring others along for the ride.

✅ Need a customer-facing specialist?

Look for a Supporter/Promoter. They’ll listen, care, and make people feel seen.

✅ Need a high-level strategist or expert?

You want an Analyzer/Driver. That’s my combo. I may not smile often, but I’ll solve the puzzle and build the system that scales it.

When you lead from this lens, people feel seen.
They stop resisting you.
They want to follow you—because you’ve put them in the right role.

And more than anything?
You stop trying to do it all yourself.

How This Shows Up Inside The Leader’s Dojo​

At The Leader’s Dojo, we don’t train leaders to bark commands or fake charisma.

We train you to:

• Master yourself
• Understand others
• Build teams that scale and endure

Here’s how we use this temperament model in everything we teach:

🧭 In Decision-Making:

You learn how your temperament skews your choices—so you can correct for bias, emotion, or overthinking.

👥 In Communication:

You modulate your tone, speed, and style to match others—building trust in minutes, not months.

💼 In Team-Building:

You stop hiring based on resumes alone and start building your inner circle based on temperamental fit.

🥋 In Conflict:

You no longer take things personally. You understand people’s “freak-out” patterns and learn how to de-escalate or redirect with precision.

This model becomes your X-ray vision.
And once you use it, you’ll never go back.

Putting It On the Mat

Let me take you back to a jobsite I was on years ago.

We had a problem. We were behind schedule.
The project manager was screaming. Everyone was blaming each other.
There was confusion, tension, and silence.

No one wanted to take responsibility.
No one wanted to step up.

That’s when I felt the familiar tug:

So I pulled the team aside and did a quick read.

• Mike? Analyzer. Needed space to think.
• Jorge? Promoter/Driver. Thrived in chaos—but needed clear direction.
• Lisa? Supporter. Overwhelmed but loyal—needed reassurance.

I gave each one what they needed.

• Shifted communication styles.
• Reassigned tasks based on temperament.
• Tightened the loop without adding pressure.

By the end of the week, the team was back on track.
Not because I barked louder.
But because I knew myself.
And I understood them.

That’s what we do in The Leader’s Dojo.​
We don’t just teach tactics.
We train awareness.
We don’t just build warriors.
We build whole humans—who can lead, love, build, and serve.

Your Move This Week

If you want to level up your leadership, here’s how to start:

1. Identify your top 2 temperaments.​
   Are you more Analyzer? Driver? Promoter? Supporter?
   Notice what energizes you—and what drains you.
2. Run a temperament read on your 3 closest people.​
   Co-worker, partner, friend.
   Use the grid. Guess their top 1-2.
   Adjust your communication for a day—and watch what happens.
3. Reflect:
   • Where do you shine as a leader?
   • Where do you struggle?
   • Who could fill that gap?
4. Train this. Don’t just know it.​
   At The Leader’s Dojo, we turn this into muscle memory.
   You don’t think—you just act. With wisdom. Precision. Presence.

Final Word:
Leadership Is a Service, Not a Status

I never wanted to be in charge.
I just wanted to help, to contribute, to do good work.
But life kept putting me in positions where someone needed to lead.

So I stepped in.
Not because I was the loudest.
But because I understood the system.

You can too.

Know yourself.
Understand others.
Build your tribe.
Lead with wisdom.

That’s the way of the warrior.
That’s the path of The Leader’s Dojo.​

Now—go put it on the mat.

P.S. If you found this content helpful, I have a favor to ask.

Actually two of them, a selfish one and a not-so-selfish one.

First the selfish one, if this was helpful to you, forward it to someone you think it might help. That helps me to grow my reach.

Now the not-selfish one, the one thing I learned on the mat and on the job was that the most successful leaders were not the ones who knew the most but were the ones who applied and taught the most.

So, if you want to be a better leader, do two things, take immediate action on what you learned today AND share it with someone else. You'll look badass, I promise you.

Also, if you have any questions, comments or suggestions, hit me up, reply to this email and let me know what's going on and how I can help you to be a better warrior, leader, and badass.
