As someone who has sold video tech courses since 2015, I don't know about the future.
I don't want to openly write about the financial side of things here but let's just say I don't have enough money to comfortably retire or stop working but course sales over the last 2-3 years have gotten to not even 5% of what it was in 2015-2021.
It went from "I'm super happy, this is my job with contracting on the side as a perfect technical circle of life" to "time to get a full time job".
Nothing changed on my end. I have kept putting out free blog posts and videos for the last 10 years. It's just traffic has gone down to 20x less than it used to be. Traffic dictates sales and that's how I think I arrived in this situation.
It does suck to wake up most days knowing you have at least 5 courses worth of content in your head that you could make but can't spend the time to make them because your time is allocated elsewhere. It takes usually 2-3 full time months to create a decent sized course, from planning to done. Then ongoing maintenance. None of this is a problem if it generates income (it's a fun process), but it's a problem given the scope of time it takes.
Were most of your sales coming via your site and/or organic search?
It sounds like you have a solid product, but you need to update your marketing channels.
