12 Ways Retirees Can Make Money Through Passive Income

8. Create an online course

If you’ve got useful info, why not monetize it? Sites like Teachable, Udemy and Thinkific will help you build a course that could change someone’s life, either professionally or personally.

Not that online courses are limited to computer-based topics. A quick search turns up classes on cake-making, watercolors, digital scrapbooking, drone cinematography, free-diving, blacksmithing, yoga, parenting, novel writing, job hunting and building a pet-care business. And that’s just for starters.

Like writing an e-book, creating a course will take some work. But again: Once it’s up, it’s up, and the work is done.
