Stop faking confidence at work: 5 ways to build genuine self-belief instead 

Words: Shamilla Mhearban

“Fake it till you make it” has become one of the most repeated pieces of career advice – and one of the most misunderstood.

At its best, it encourages us to act before confidence arrives. At its worst, it tells us to perform a version of competence we haven’t earned and hope nobody notices.

Those are not the same thing.

As an executive coach, I often work with people who are already highly capable. Their problem isn’t a lack of evidence that they can do the job. It’s that their confidence hasn’t caught up with the level at which they’re now expected to operate.

A promotion leaves them feeling exposed. A bigger room makes them second-guess themselves. They’ve been given more responsibility, but privately, they’re waiting to feel like the person who deserves it.

That feeling can lead to two mistakes: shrinking until they feel ready, or pretending so hard that they stop learning.

There is a better option. Don’t fake competence. Practice courage.

1. Stop waiting to feel confident

Confidence is often treated as a prerequisite for action: first, I feel confident; then I speak up, apply for the role, lead the meeting or make the decision.

In practice, the sequence frequently runs the other way.

You take the action. You survive it. Your brain gains evidence that you can handle it. Gradually, your sense of who you are expands to include the thing that once felt unfamiliar.

That isn’t faking it. It’s building evidence.

The distinction matters because genuine confidence isn’t about knowing you’ll succeed. It’s about trusting yourself to respond when things become difficult.

That kind of confidence is far more useful at work, particularly in senior roles where you can’t anticipate every challenge or prepare for every eventuality.

2. Redefine what confidence looks like

When people are told to act confidently, they’re often handed a narrow template for what that means: speak first, speak loudly, never hesitate, take up more space and project certainty.

Those behaviours can be rewarded in workplaces, but they aren’t the same as confidence.

Our ideas about leadership presence have often been shaped by traditionally masculine-coded behaviours, such as dominance, decisiveness and visible certainty. As a result, quieter forms of authority can be overlooked.

Confidence can also look like pausing before you answer. Asking a precise question instead of rushing to fill the silence. Holding a boundary calmly. Saying “I don’t know” without diminishing yourself. Listening closely enough to change your mind, or making a decision without needing to dominate the room.

The goal isn’t to train people, particularly women, to imitate a louder model of leadership. It’s to help them feel more secure in their own authority.

Instead of asking, “How would a confident person behave?”, try asking: “What would grounded authority look like for me in this situation?”

You might speak less, but with greater clarity. You might slow the pace of a conversation rather than compete with it. You might stop over-explaining a decision or allow a moment of silence after making your point instead of immediately softening it.

Confidence isn’t always about becoming more visible. Sometimes, it’s about becoming less apologetic about the way you already lead.

3. Build an evidence bank

Low confidence has a selective memory.

It remembers the meeting where you stumbled and forgets the 20 in which you contributed well. It magnifies the feedback that hurt and discounts the promotion, client result or difficult situation you successfully handled.

One way to challenge this is to create a record that’s harder for your inner critic to edit.

Write down specific evidence of your competence: decisions you’ve made, problems you’ve solved, positive feedback you’ve received, difficult conversations you’ve handled and occasions when someone sought your judgement.

Not affirmations. Evidence.

Before a high-stakes meeting, presentation or interview, review it. You aren’t trying to convince yourself that you’re extraordinary. You’re reminding yourself of information you may struggle to access when the pressure rises.

4. Try the 10% rule

If a behaviour feels completely unnatural, making an enormous leap can backfire. You can end up feeling as though you’re performing rather than developing genuine confidence.

Instead, ask yourself: what would 10% more confidence look like here?

Perhaps you contribute earlier in the meeting rather than waiting until the end. You hold eye contact for slightly longer. You stop filling the silence after making your point. You volunteer for a piece of work that stretches you without requiring you to misrepresent your expertise.

Small changes can help you build new experiences without tipping you into theatre.

You don’t need to become louder, harder or more certain to become more credible. You need to become more deliberate.

5. Never fake what you don’t know

There’s one thing you should never pretend to have: knowledge you don’t possess.

Confidence includes being able to say “I don’t know”, “I need help” or “That sits outside my expertise”.

The more senior you become, the more dangerous performative certainty can be. Bluffing might get you through a conversation, but it can undermine trust when the gaps become apparent.

People are more likely to trust leaders who combine conviction with intellectual honesty than those who pretend to have every answer.

Admitting what you don’t know doesn’t make you less credible. It shows that you understand the limits of your expertise and are prepared to take responsibility for finding the answer.

So, should you fake it till you make it?

I’d retire the phrase.

Instead, act slightly ahead of your confidence while staying firmly connected to your competence.

You don’t need to become a different person before you take up more space at work. You need repeated experiences that show you that the person you already are can handle more than your self-doubt has been allowing you to believe.

Real confidence isn’t pretending you have nothing to learn. It’s trusting yourself enough to keep learning, even when other people are watching.
