The Cookie Jar: Building Mental Strength for Calm, Consistent Leadership
Life throws things at us. Leadership amplifies that.
Prefer to listen? You can play the episode below:
I want to talk about a guy who polarises people a little bit — but whose ideas on resilience are hard to ignore, David Goggins. More specifically, one of his mental models known as The Cookie Jar.
Now, before anyone rolls their eyes and thinks this is going to be about screaming at yourself in the mirror — stay with me. There’s a leadership application here that’s powerful when used correctly.
Who Is David Goggins (And Why Should Leaders Care?)
Goggins is a former U.S. Navy SEAL, ultra-endurance athlete, and author of Can't Hurt Me and Never Finished.
His backstory is confronting:
Grew up in an abusive household
Struggled with obesity
Faced learning difficulties and serious self-doubt
Lost over 100 pounds to qualify for Navy SEAL training
Completed SEAL training, Ranger School, and Air Force Tactical Air Controller training
Went on to compete in ultra-marathons and set endurance records
He’s blunt. Very blunt. Every second word can be an F-bomb. But behind the delivery is a core philosophy built around discipline, personal responsibility, and deliberately embracing discomfort to build mental strength.
And while his methods are extreme, the underlying principle is deeply relevant to leadership, because leadership is uncomfortable.
The Cookie Jar Theory
Here’s the idea.
When you go through something hard — really hard — you put that experience in your “cookie jar.”
The jar represents proof.
Proof that:
You’ve suffered before.
You’ve survived before.
You’ve overcome before.
You’re capable of more than your mind tells you.
Then, when you hit another difficult moment, you reach into that jar and remind yourself what you’ve already conquered. Not hypotheticals. Not positive affirmations. Not wishful thinking.
Evidence.
Why This Matters for Leaders
Leadership isn’t physically brutal like running 100 miles. But mentally? Emotionally? It can be relentless.
You’ll face:
Conflict you didn’t ask for
Performance issues that drain you
Organisational change you can’t control
Decisions where no option makes everyone happy
Periods where you feel completely out of your depth
And here’s the thing — when those moments hit, your brain lies to you.
It says:
“You’re not cut out for this.”
“You’re the only one struggling.”
“You’ve never handled something this hard.”
That’s when you need your cookie jar.
What Goes in a Leadership Cookie Jar?
Not just big wins.
In fact, often it’s the opposite.
It’s:
The first tough conversation you didn’t avoid.
The project that nearly broke you — but didn’t.
The team conflict you navigated without losing your composure.
The period where you were exhausted but still showed up for your people.
The time you thought you were failing — and learned instead.
These are mental receipts, and emerging leaders, especially, underestimate how much they’ve already built.
Calm Leadership in Times of Change
One of the biggest applications of this concept is during organisational change. When restructures happen, or
budgets tighten. When strategies pivot, and uncertainty creeps in. In these scenarios, your team needs steadiness.
And steadiness doesn’t come from pretending things aren’t hard. It comes from knowing you’ve handled hard before.
You reach into your jar and think:
“I’ve dealt with ambiguity.”
“I’ve led through stress.”
“I’ve had tough seasons.”
“I didn’t fold then. I won’t fold now.”
That internal dialogue changes your external presence.
And your team feels that.
This Isn’t About Becoming Extreme
Now, let’s be clear. This is not about turning yourself into an ultra-endurance machine or glorifying burnout, and it’s definitely not about screaming motivational quotes at your reflection.
As leaders, we need sustainability, but we also need resilience. The cookie jar isn’t about punishment — it’s about perspective.
It reminds you that:
Discomfort isn’t new.
Growth isn’t clean.
You’re more capable than you give yourself credit for.
A Practical Exercise
Here’s something simple you can do this week. Write down five moments in your leadership journey that stretched you. Not the polished LinkedIn achievements. The real ones, even the messy ones. The moments you doubted yourself — but kept going anyway.
That list becomes your jar.
And when this year inevitably throws something at you (because it will), you don’t spiral. You reference.
You ground yourself in evidence.
Final Thought
Life throws things at us. Leadership amplifies that.
You won’t avoid adversity.
You won’t eliminate pressure.
You won’t feel confident every day.
But you can build a body of proof.
And over time, that proof turns into quiet confidence.
Not loud.
Not performative.
Just steady.
And steady leaders are the ones people follow when things get hard.
Here’s to building a very full cookie jar.
