You Don’t Have to Know It All. You Just Have to Keep Learning.

There is a particular moment in a meeting that can strike fear into the heart of even the most experienced professional.

Someone asks a question.

There is silence.

Then, slowly, every head at the table turns toward you.

Apparently, somewhere between your first cup of coffee and this meeting, you were promoted to Keeper of All Human Knowledge.

Excellent.

You smile confidently while your brain frantically searches through twenty years of experience, three degrees or certifications, seventeen webinars, a conference you attended in 2014, something you vaguely remember reading on LinkedIn, and possibly an episode of Jeopardy!.

And then you realize something.

You don't know the answer.

For many professionals, those may be five of the hardest words in the English language:

“I don’t know the answer.”

But they shouldn't be.

Somewhere Along the Way, We Confused Expertise With Knowing Everything

The longer we work in a profession, the more people expect us to know.

And, perhaps more dangerously, the more we expect ourselves to know.

If you're the auditor, you're supposed to understand the controls.

If you're the project manager, you're supposed to know what's happening with the project.

If you're the executive, surely you're supposed to have the answers.

If you're the consultant, trainer, accountant, engineer, attorney, risk professional, or subject matter expert, people came to you for answers.

So admitting that you don't know something can feel uncomfortable.

But here's the problem.

The world isn't exactly slowing down while we catch up.

AI is changing how we work. Technology is changing how projects are managed. Risks are emerging that weren't on anyone's risk register five years ago. Regulations change. Industries change. Fraudsters change their tactics. Customers change their expectations.

Even the language changes.

Just when you finally figured out AI, someone started talking about generative AI.

Then came agentic AI.

At this rate, by next Tuesday we'll probably be discussing AI that has hired its own staff and is complaining about the coffee in the break room.

The point is simple:

Nobody knows everything anymore.

I'm not convinced anybody ever did.

“I Don’t Know” Is Not the End of the Conversation

There is an enormous difference between:

“I don't know.”

and

“I don't know, but I'll find out.”

The first can be a stopping point.

The second is the beginning of learning.

Some of the smartest people I've met throughout my career weren't the ones who immediately had an answer for everything. They were the ones who asked another question.

Why?

How do we know that?

What happens if we're wrong?

Has anyone actually tested that assumption?

And one of my personal favorites:

Can you explain that to me in plain English?

Curiosity is one of the most underrated professional skills we have.

Because curiosity leads to questions.

Questions lead to understanding.

Understanding leads to better decisions.

And occasionally, questions lead to discovering that something everyone has been doing for the past ten years makes absolutely no sense whatsoever.

Those are particularly fun days for auditors.

Expertise Isn't a Destination

We sometimes talk about expertise as though one day we finally arrive.

Congratulations!

You've reached EXPERT.

Please collect your certificate at the door. You may now stop learning.

Except it doesn't work that way.

The more you learn about something, the more you begin to realize how much more there is to learn.

That's not failure.

That's growth.

Think about something you know really well today. Maybe it's project management, audit, construction, fraud, leadership, photography, technology, or something completely different.

Now think back to what you knew about it five or ten years ago.

Hopefully, you're better today.

You see things differently. You recognize patterns faster. You ask better questions. You've made mistakes and learned from them. You've watched other people make mistakes and, if you were particularly clever, learned from those too.

Your expertise didn't arrive one morning.

You built it.

One question, one experience, one mistake, one class, one conversation, one book, and one slightly uncomfortable “I don't know” at a time.

Give Yourself Permission to Be a Student Again

This may be one of the most powerful things experienced professionals can do.

Become a beginner.

Take a class in something you know very little about.

Ask the junior person on your team how something works.

Learn a new technology.

Read outside your profession.

Talk to people who see the world differently than you do.

Ask a question that you worry might sound stupid.

And when someone uses an acronym you've never heard before, resist the temptation to nod wisely while secretly hoping someone else asks what it means.

Ask.

Chances are half the room doesn't know either.

They'll just be incredibly grateful that you were brave enough to say it first.

Learn It. Grow It. Own It.

This is one of the ideas at the heart of LG3.

Learn It.

Give yourself permission not to know everything. Stay curious. Ask questions. Explore ideas. Keep adding tools to your professional toolbox.

Grow It.

Knowledge becomes powerful when you do something with it. Apply it. Challenge it. Practice it. Make mistakes with it. Adjust it. Share it.

And then...

Own It.

Make that knowledge yours.

Not because you memorized a slide or passed a test, but because you understand it well enough to use it confidently when it matters.

That's growth.

And perhaps that's the real definition of expertise.

Not reaching the point where you finally know everything.

But reaching the point where you're comfortable knowing that you never will.

So the next time you're sitting in that meeting and every head slowly turns toward you...

Take a sip of coffee.

Smile.

And if you don't know the answer, say:

“I don't know yet. But let's find out.”

Because learning doesn't make you look less knowledgeable.

It makes you better.

Learn it. Grow it. Own it.

And then wake up tomorrow and learn something else.
