Earn Cash by Teaching What You Know
Another way to make money online today is to teach what you know. You don’t have to have a degree, and it doesn’t even have to be a new idea to earn as much as six figures (some make more) every single year.

Tutor Others in Your Subject
You can make it super-simple by merely offering to tutor others in the subject you’re an expert in. You can often make $20 per hour or more tutoring kids, college students, and others in the topics they need to learn. If you are well versed in test-taking skills, you can also tutor people to excel in standardized testing like the ACT or the SAT.
Create an Online Course
Anything you know how to do, from making cakes to sewing pillows to doing complicated math, can be turned into an online course. You can video the lessons or write them using multimedia including text, video, audio, interactivity and more. Then deliver the lessons via a system like Teachable.com or membership site using software like aMember.com.
Start a YouTube Channel
You can also earn via advertising and membership by starting a YouTube channel to teach your audience about the topic you’ve chosen. Whether it’s about marketing or hair care, anyone can make it on YouTube if they try. At first, you’ll have to build up your audience to earn the monetization of your channel, but even before that (depending on your niche), you can earn money via donations, memberships, and sponsorships.
