How to Turn What You Already Know Into an Online Course

My neighbor is a dental hygienist who created a $47 Udemy course about flossing with braces. She earns $200–$400/month from it without a single follow-up. You just need to know something useful.

The "One Step Ahead" Principle

You don't need to be the world's top expert. You just need to be one step ahead of your student.

Validate Before You Build

Before recording a single video, post in Facebook groups asking if people would pay $X to learn Y. If five people pay $50 each upfront, you have proof and $250 to fund your time.

Where to Host

• Udemy — Built-in audience, lower margins, good for beginners
• Teachable / Thinkific — Your own brand, higher margins
• Gumroad — Simple, low fees, great for mini-courses

Minimum Viable Course

A 90-minute course shot on your phone in good natural light is enough. Perfection is the enemy of published.

Realistic Earnings

A $47 course selling 10 copies a month earns $470 passively. Scale to 3 courses and you're at $1,400+/month from content you made once.
