How to Find the Right Topic for Your Course
Your existing expertise is the best starting point — here's how to focus it into a course topic people actually want
The right course topic sits at the intersection of what you already know well, what genuinely excites you, and what people are actively seeking help with. You don't need a revolutionary idea — you need a focused one.
If you're a coach, author, speaker, consultant, therapist, artist, or educator, you've spent years developing expertise that other people want to learn. The question isn't whether you have enough knowledge to teach a course. It's how to channel that knowledge into something focused and valuable.
This might feel like a leap. After all, knowing something and teaching it are different skills. But teaching is one of the most powerful things you can do for your business and your impact. As author and business strategist Pamela Slim has observed, the best thing you can do to be a great businessperson is to be a great teacher. Teaching builds relationships that last. It creates repeat customers, generates referrals, and establishes you as a trusted authority — not because you claimed to be one, but because you demonstrated it.
Why Your Existing Expertise Is Enough
The most successful course creators don't start with a revolutionary idea. They start with something they already know well and care about deeply.
Sally Hirst had been teaching mixed-media art in Norwich, England, for over 40 years — mostly in-person workshops and local classes. When COVID shut down her studio in 2020, she started posting free lessons on YouTube. Within six weeks, she had 5,000 viewers and 3,000 email subscribers. She turned that momentum into structured online courses on Ruzuku, and today she teaches more than 5,000 students worldwide across 10+ courses.
"Ruzuku has changed my life… my income is 10x what it was in 2019!"
— Sally Hirst, Artist & Art Educator
Sally didn't invent a new art technique. She took what she'd been teaching for decades and brought it online.
Wendy Bailye of The Felt Studio had a similar pivot. She'd been teaching feltmaking in person and traveling overseas for workshops. When COVID halted that life, she brought her teaching to Ruzuku — not because she had a grand plan, but because she had students who still wanted to learn.
"Post COVID my teaching life came to a halt… Ruzuku has allowed me to still make an income and get the lovely feeling of connecting with my students again."
— Wendy Bailye, The Felt Studio
And Janae Bower took her expertise in an entirely different direction — she built 30+ courses for three distinct audiences: corporate teams, personal growth seekers, and faith-based communities. All from the same core body of knowledge, adapted for different contexts.
"The flexibility and variation of how I can set up these courses has been wonderful."
— Janae Bower
How Do You Narrow Down Your Topic?
The challenge for most aspiring course creators isn't having too little expertise — it's having too much. Here's how to focus:
- Start at the intersection. What you know deeply + what excites you + what people are actively seeking help with.
- Get specific. "Photography" is too broad. "Product photography for Etsy sellers" is a course topic. "Watercolor painting" is enormous. "Loose watercolor florals for beginners" is something people search for, buy, and complete.
- Look for demand signals. Are people asking questions about this topic in forums, Facebook groups, or Reddit? Are there existing courses? (Competition is a good sign — it means there's a market.) Have at least a handful of people asked you for help with this specific thing?
Would You Teach This for 10 Years?
Here's a useful filter: would you be happy teaching this topic for the next 10 years? That might sound dramatic, but the creators who build the most sustainable course businesses are the ones who chose topics they don't get tired of.
Manuel Puro has been teaching acting and casting mastery on Ruzuku for more than a decade, reaching thousands of students. He chose a topic at the intersection of his passion and his students' ambitions, and that sustained him through thousands of lessons, launches, and iterations.
"It's not an overestimation to say you've transformed my life and the lives of thousands of my students."
— Manuel Puro, Puro Casting
You don't need to commit to a decade right now. But choosing a topic you'd be excited to explore for years — not just weeks — is a strong signal that you're on the right track.
