The More I Learned, The Less Certain I Became

There was a point, about a year into my nursing career, where I thought I had it figured out.

I'd worked in a small rural hospital and on an acute stroke ward. I'd found my rhythm. I could manage a patient load, prioritise tasks, administer medications and answer most of the questions that came my way. The anxiety that had followed me through my graduate year had largely disappeared.

For the first time, I felt confident.

Looking back more than twenty years later, I realise something that would have surprised my younger self.

I wasn't becoming competent.

I was becoming comfortable.

Those two things are very different.

At the time, I couldn't tell the difference. Like many early career nurses, I assumed confidence was evidence that I was becoming a better clinician. The less nervous I felt, the more I believed I knew.

In reality, I was simply operating within the limits of what I had already experienced.

The patients I had looked after were beginning to fit familiar patterns. The problems were becoming recognisable. I knew what "normal" looked like because I had seen it often enough.

What I didn't appreciate was how much existed outside those patterns.

I didn't know what I didn't know.

And that's a dangerous place to stand when you don't realise you're standing there.

Emergency Nursing Changed Everything

That illusion didn't last long.

Within my first few shifts in the Emergency Department, I looked after a patient whose condition was deteriorating.

Looking back now, the signs seem obvious.

There had been a significant change in their mental state. It wasn't subtle. It wasn't hidden. It was there for anyone with the experience to recognise.

Except I didn't.

Not because I didn't care.

Not because I wasn't paying attention.

But because I had never seen that presentation before.

I wasn't looking for those symptoms because, in my mind, they weren't part of the pattern.

That's the thing about inexperience.

It isn't simply the absence of knowledge.

It's the inability to recognise the gaps in your own understanding.

I walked away from that shift humbled.

Not because someone criticised me.

Not because there was blame.

But because I realised something uncomfortable.

I had been certain the patient was fine.

My certainty wasn't based on expertise.

It was based on the limits of my experience.

I was only looking at what I knew.

I hadn't accounted for what I didn't know.

That lesson has stayed with me for the rest of my career.

What I Thought Made a Good Nurse

When I was a graduate nurse, I had a very clear picture of what a "good nurse" looked like.

They knew every answer.

They knew every medication.

They never hesitated.

They never asked questions.

They certainly never asked for help.

From the outside, they looked completely in control.

I spent years trying to become that nurse.

Today, after more than two decades working across emergency nursing, trauma care, rural health, clinical governance and patient safety, my definition has completely changed.

The nurses I admire most aren't the ones who always have the answer.

They're the ones who ask the best questions.

They're curious.

They seek another opinion.

They challenge their own assumptions.

They recognise the limits of their knowledge long before those limits become a problem for their patient.

Some of the safest clinicians I've ever worked with regularly say things like:

"Can you have a look at this?"

"Something doesn't quite fit."

"What do you think?"

"Am I missing anything?"

Twenty years ago, I would have mistaken those questions for uncertainty.

Today, I recognise them as wisdom.

The Confidence Trap

Over the years I've worked with hundreds of nurses.

Some arrived quietly, doubting themselves despite being exceptionally capable.

Others arrived full of confidence, speaking with authority and certainty from day one.

Confidence is persuasive.

It makes us sound knowledgeable.

It makes us appear capable.

But confidence can also become a trap.

I've watched talented nurses stop developing because they believed they already had the answers.

When we stop questioning ourselves, we stop learning.

When we stop learning, our growth slows.

The danger isn't confidence itself.

Healthy confidence allows us to lead, make decisions and reassure frightened patients.

The danger is believing confidence and competence are the same thing.

They aren't.

Confidence is how certain we feel.

Competence is built through experience, reflection and thousands of small lessons that quietly accumulate over years.

One can exist without the other.

What Patient Safety Taught Me

Later in my career I moved into clinical governance and patient safety.

Instead of caring for one patient at a time, I began reviewing safety events across entire health services.

Hundreds of incidents.

Perhaps thousands.

Every one of them represented a story.

A patient.

A family.

A clinician who arrived at work intending to do their best.

One of the biggest surprises wasn't how often inexperienced clinicians were involved.

It was how rarely incompetence was the real cause.

Most clinicians knew what they were trying to do.

The problem often lay elsewhere.

Assumptions.

Communication failures.

Hierarchy.

Distractions.

Time pressure.

And, sometimes, certainty.

Someone assumed they were right.

Someone didn't ask another opinion.

Someone accepted the first explanation because it fit the pattern they already knew.

Reviewing those incidents changed how I think about mistakes.

Clinical errors are rarely the result of people not caring.

More often, they happen because human beings are trying to make sense of incomplete information inside complex systems.

The greatest protection against that isn't intelligence.

It's curiosity.

It's humility.

It's the willingness to ask one more question before making the next decision.

The Best Nurse I Ever Worked With

The best emergency nurse I've ever worked alongside wasn't the loudest person in the room.

In fact, they were probably one of the quietest.

An experienced trauma nurse with decades of clinical practice.

They never dominated conversations.

Never tried to prove how much they knew.

Never made anyone else feel small.

What stood out wasn't their technical ability, although that was exceptional.

It was their constant curiosity.

Despite having seen almost everything emergency nursing could throw at them, they would still ask for another opinion.

"Can you have a look at this?"

"Does this concern you?"

"What do you think?"

At first, I found it surprising.

Why would someone with that much experience still ask questions?

Eventually I understood.

Experience hadn't made them certain.

It had taught them how dangerous certainty could be.

Their questions became teaching moments.

Junior nurses learned from them.

Senior doctors respected them.

The entire team listened when they quietly said,

"Something isn't right."

Not because they always knew the answer.

But because everyone understood that if someone with decades of experience thought a pattern didn't fit, it was worth paying attention.

That is real clinical confidence.

Not the confidence to always be right.

The confidence to keep questioning.

Every Nurse Carries a Different Library

People often describe Emergency Departments as chaotic.

From the outside, they are.

Patients arrive every few minutes.

Ambulances keep coming.

Conditions change rapidly.

Decisions are made under pressure.

But after enough years working in emergency care, something shifts.

You realise emergency nursing isn't just about managing chaos.

It's about recognising patterns.

Every patient is subconsciously compared to thousands you've cared for before.

Does this fit?

Does something feel different?

What's missing?

What's unusual?

That ability doesn't develop because you memorised another textbook.

It develops because you've slowly built your own internal library of experiences.

Every nurse carries a different library.

One colleague has years in paediatrics.

Another spent a decade in intensive care.

Someone else knows oncology inside and out.

Another has worked in remote communities where resources are limited and clinical judgement becomes even more important.

No single nurse has every book.

And that's exactly why healthcare is a team sport.

When we ask for another opinion, we're not admitting weakness.

We're borrowing a book from someone else's library.

We're adding another perspective.

Another pattern.

Another piece of evidence.

The safest teams I've worked in weren't made up of people who always agreed.

They were made up of people who were comfortable asking,

"What am I missing?"

Why I Feel Less Confident Today

If you'd asked me twenty years ago whether I'd be more confident after two decades in nursing, I would have answered without hesitation.

Of course.

Instead, something unexpected happened.

In many ways, I feel less confident today than I did after my first year.

Not because I know less.

Because I know more.

I've seen how quickly patients can deteriorate.

I've seen how small communication failures can have enormous consequences.

I've reviewed incidents where good clinicians made understandable mistakes.

I've learned that medicine is full of exceptions.

I've realised that no matter how long I spend in emergency nursing, there will always be presentations I haven't seen before.

There will always be something left to learn.

Ironically, while my confidence has softened, my judgement has strengthened.

I trust my ability to assess a situation.

I trust my ability to ask for help.

I trust my ability to recognise when something doesn't fit.

But I trust certainty far less than I once did.

And I think that's made me a better nurse.

The Kind of Nurse I Hope We All Become

If there's one lesson my career has taught me, it's this:

Confidence isn't the goal.

Competence isn't the destination either.

The real goal is to remain curious for an entire career.

To keep learning.

To keep reflecting.

To remain humble enough to admit when we don't know.

To understand that every patient, every colleague and every shift has something new to teach us.

The nurses I respect most haven't reached a point where they know everything.

They've reached a point where they're comfortable saying they don't.

Looking back now, I don't wish I'd become confident sooner.

I wish I'd learned sooner that confidence without curiosity is fragile.

Competence isn't built by believing you have all the answers.

It's built one shift at a time.

One mistake reflected on.

One difficult conversation.

One question asked.

One lesson carried into the next patient.

Perhaps that's why, after all these years, I still love nursing.

Not because I've mastered it.

But because every shift reminds me that mastery was never the point.

Learning was.
