How to Become an Expert in a Field You Have No Expertise In

A hill I will die on: it’s never been easier to learn than it is right now. From YouTube University to creators, you don’t need a background or degree to become a recognized, trusted expert. 

With that in mind, you can pivot and become an expert in a field you have no expertise in. 

I’ve done it, and I know several of the folks in my network and client base have too: 

  • One who started their career as a NASA scientist and is now a strategic advisor and expert in the enterprise tech space 

  • One who works for Big Tech but is also a gaming expert 

  • One who got a sports nutrition degree and now runs a million-dollar content agency 

The point is, you can do it. I’m doing it myself by learning everything there is to know about the creator economy. 

Here’s how. 

Have a genuine passion for it

You'll spend a lot of time, energy, and effort mastering this field, so it needs to be something you're genuinely excited about.

That excitement shows up in your content. It's a whole lot easier to create when you're curious about what you're creating, and your audience can feel the difference.

A common mistake I see is jumping on whatever topic is dominating the zeitgeist, hoping to catch the next big thing (right now, it’s AI). 

The question to ask is whether you're looking at a trend or a shift. Trends are tied to a moment and fade with it.

Shifts change how an industry, a behavior, or a culture works, and they have staying power. This matters because whatever topic you choose to become an expert in becomes a brand association linked to you, and once you build those, they're hard to change.

The sweet spot is finding the intersection of what you genuinely love, what your audience is actively seeking, and where the larger cultural conversation is heading. Once you find it, you can put your own spin on it, rooted in your past experiences. That’s what will make your expertise yours.

Then ask yourself one question: Could you easily make 10,000 pieces of content on this topic? If the answer is yes, you've found something with real depth, and the curiosity to match it. If not, keep refining the angle until the ideas start coming effortlessly.

Learn and collaborate from experts in that field 

Every field has its own thought leaders, influencers, etc., who shape the conversation. Some are the established names everyone references, and others are rising voices.

Once you start consuming content in your field, you'll notice the same names coming up again and again. Those are the people who are the forward thinkers in that industry, the ones to learn from (and that one day you aspire to be!).

Subscribe to their content. Follow them on social. Pay attention to how they think. Notice the questions they ask, the patterns they spot, and the way they frame problems. 

Then go a step further and build relationships. Connect with them, comment thoughtfully on their work, share your own take, and reach out when you have something useful to offer (especially if they’ve asked for it). 

Collaboration is also one of the best content strategies. Interviewing an expert, co-hosting a conversation, or building a piece of content together gives you access to knowledge you couldn't get alone, and it signals to your audience that you’re opening yourself up to different perspectives to expand upon what you know. 

And don't overlook your peers—they are a great way to get your feet wet with doing collaborations. Most of the time, they might already be fans of yours, so it’s easier to make the ask than someone who feels like a celebrity in your industry.

Consume everything you can around it 

Knowledge is power, and that knowledge starts with education. When you want to learn about a new field, strive to consume as much as you can around it.

The trick is knowing where to look, because different sources teach you different things. Think about it in three tiers:

How the field works

Start here to understand the basics, the origin story, and the logic everything in the industry is built on:

  • Foundational books

  • Academic papers and research reports

  • Industry history and key turning points

  • Vocabulary, jargon, and acronyms insiders use

  • Industry norms and status quo

What's happening now

This tier keeps you current on the conversations in the field, along with who's leading it:

  • Podcasts and newsletters

  • Trade publications and analyst reports

  • Articles and short-form content

  • Conference agendas, webinars, and recorded talks

  • Earnings calls and investor decks

What's coming next

This is where forward thinkers live:

  • Practitioner communities like Reddit, Discord, and Slack groups

  • Job postings, which reveal emerging skills and roles

  • Funding announcements and acquisitions, which show where the money is betting

  • Regulatory proposals and policy shifts

  • Fringe and contrarian voices

Across all three tiers, pay attention to:

  • Changes

  • Trends

  • Challenges

  • Sentiment

  • Key players

  • Economics

  • Active debates

  • Adjacent fields

  • Forward-looking signals

Apply what you’ve learned by creating content around it 

Creating is the best form of thinking. Consuming keeps you informed, but fluency comes from what you do with the information. 

When you create content, you're forced to organize what you know, form a point of view, and test it against what others in the field are saying. That's how knowledge turns into expertise.

The most common thing holding people back is the feeling that they haven't earned an opinion yet. But you don't need to be the expert to start creating. Some of the most compelling content comes from someone learning in public, because the audience gets to grow alongside them.

This is where knowing your storytelling archetype becomes key. Your archetype shapes how you naturally make sense of information and share it with others, whether that's documenting the journey, translating complex ideas into simple ones, or challenging the conventional take. 

A few ways to start:

  • Share what surprised you most about something you just learned.

  • Break down a trend or report in your own words.

  • Connect an idea from the field to something from your past experience.

  • Take a stance on one of the field's active debates.

With every piece you create, you hone your POV and perspective. The more you create in that field, the bigger your body of work, and the more people start to see you as an expert.

Trust your expertise

At some point, you'll feel the gap between how much you know and how much there is to know. That feeling is a sign you're learning the field deeply, and it never fully goes away.

Remember that you're bringing something no one else has: your past experience. The skills, industries, and perspectives you carry with you are what make your take on this field distinct. A lot of the most interesting ideas come from people who connect a new space to something they already know well.

Expertise is also a spectrum. You don't need to know everything to be valuable; you just need to be a few steps ahead of your audience in their knowledge and understanding of the field. If you can help someone understand something more clearly than they did before, you're already operating as an expert.

And when the doubt creeps in, look at the evidence. Every piece of content you've created, every conversation you've had, and every connection you've drawn between ideas proves what you know. Confidence comes from that body of work. Trust it, keep building on it, and let your point of view lead.
