šØ Want unshakable confidence? Stop borrowing it. Start building it.
Early in your career, confidence comes from external validation; praise from your boss, a nod of approval in meetings, a positive review. But true confidence isnāt about what others think. Itās about trusting yourself.
The moment you stop second-guessing, over-explaining, and seeking permission = thatās when real confidence begins.
I wrote about this shift because itās a game-changer. If you read one thing today, make it this. ā¬ļø
At the beginning of your career, decision-making can feel like a minefield. You second-guess your instincts, over-explain your ideas, and seek constant validation from your manager, peers, or mentors. Every time youāre asked a question, your brain races to calculate:Ā Whatās the ārightā answer? What will people think if Iām wrong?
Letās be honest, early on, you donāt trust yourself much at all.
You over-prepare for presentations, afraid of sounding uninformed. You second-guess decisions, assuming someone else surely knows better. You watch the faces of others when you speak, silently measuring whether your opinion landed or if youāve just embarrassed yourself.
Itās exhausting. But itās normal.
In those early stages, your confidence is almost entirely borrowed from external sources. You feel capable when your manager praises you. You feel smart when a client agrees with you. You feel validated when you receive a positive performance review.
But without that external reinforcement, your confidence crumbles because deep down, you donāt actually trust yourself yet.
And thatās okay.
The Shift: Building Trust with Yourself
Something remarkable happens as you progress in your career but only if youāre paying attention.
You begin to build trust with yourself. And that, more than any promotion or praise, is what fuels long-term confidence. Yet, few people talk about it.
We spend countless hours discussing trust in teams, earning trust from leaders, or fostering trust in organizations. But what about the trust we build within ourselves? The trust that says:
Iāve got good instincts.
I know what Iām doing.
Even if I get this wrong, Iāll figure it out.
Then something shifts; slowly, quietly, subtly.
You make a big decision at work, and it works. You speak up in a meeting, and your point shifts the conversation. You take on a challenging project, and despite initial doubt, you figure it out.
And suddenly, you realize:Ā Wait a second⦠I know what Iām doing.
Itās not loud. Itās not a big celebratory moment. Itās more like a steady drumbeat in the background, the voice inside you becoming clearer, stronger, and more assured.
How Self-Trust Shows Up
The funny thing about self-trust is that it doesnāt announce itself. It doesnāt show up as bravado or arrogance. Instead, it reveals itself in smaller, quieter ways:
You stop rehearsing your thoughts before speaking in meetings because you trust that your ideas, unpolished or not, have value.
You donāt panic when you make a mistake; instead, you instinctively shift toĀ How do I fix this?Ā instead ofĀ Iām a failure.
You compare yourself to others less. Their success doesnāt threaten you because youāve built your own solid ground.
You sayĀ I donāt knowĀ without shame, knowing that it doesnāt diminish your worth.
You stop people-pleasing because your goal is no longer approval,Ā itās impact.
This is what it feels like to trust yourself.
Why Self-Trust Makes You a Better Leader
When you build deep trust with yourself, something interesting happens: you become better at building trust with others.
Why? Because youāre no longer performing.
Youāre not trying to sound smart, appear competent, or win approval. Youāre simply showing up; grounded, clear, and confident. And when people encounter a leader who trusts themselves, they instinctively trust that leader too.
This is why the most compelling leaders arenāt necessarily the loudest or most charismatic. They are the ones most certain about who they are and how they lead. Their certainty creates psychological safety for others.Ā And where does that certainty come from? Self-trust.

How to Build Self-Trust (Hint: You Canāt Fast-Track It)
The frustrating truth about self-trust is that it canāt be rushed. It doesnāt come from reading books about confidence or attending leadership seminars. It comes from one thing only:Ā repeated evidence that you can rely on yourself.
That means:
Making decisions without having all the answers and discovering youāre capable.
Taking responsibility when you get something wrong and realizing you can recover.
Offering your ideas without obsessing over how theyāll be received and watching them resonate anyway.
Facing hard conversationsĀ without someone from HR mediatingĀ and realizing you can handle it.
The more you collect proof that you can trust yourself, the less youāll need validation from others.Ā And thatās when your confidence stops being borrowed and starts being built.

The Confidence You Canāt Lose
Hereās the part no one tells you: Confidence doesnāt always look like standing tall, speaking boldly, or dominating a room. Real confidence, the kind born from deep self-trust, is quieter.
Itās walking into a high-stakes meeting without mentally rehearsing every possible response.
Itās making a tough decision without needing universal agreement.
Itās admitting when youāre wrong without crumbling internally.
Itās being comfortable with silence because you donāt feel the need to fill it.
Itās the kind of confidence that doesnāt scream: it simplyĀ is.
And once you have it, you realize something profound: You spent the first half of your career trying to build confidence. But the real turning point came when you simply learned to trust yourself.
And from that, everything else: clarity, impact, leadership; flows effortlessly.
Where Are You in This Journey?
If youāre early in your career and still struggling to trust yourselfāthatās okay. Weāve all been there. Keep collecting proof that you can rely on yourself, and eventually, you wonāt need external validation to feel confident.
If youāre further along and starting to feel that deep, unshakable sense of inner trust, protect it fiercely. Because itās the quiet engine behind every great leader, confident voice, and decisive career move.
And if youāre somewhere in between, wondering when confidence will finally feel effortless, remember this:
It doesnāt come from what others think of you. It comes from whatĀ youĀ think of you.
So keep showing up. Keep taking risks. Keep trusting yourself.
Because the day you realize you can rely onĀ you,Ā is the day youāll finally feel confident.
And once you have that?Ā No one can take it from you.
