Sell blood or donate plasma. Plasma is a component of blood, and the process of extracting it is similar to donating blood: your blood is drawn, the plasma is separated, and the red blood cells are returned to your body. Laws may not technically permit you to sell your plasma, but you can be compensated for your time spent donating. In the United States, you can make about $200 a month by registering with a plasma center near you.
Those who love teaching but would prefer to make passive income could consider teaching online courses. With online courses, you can teach topics that go beyond what a tutoring gig for students would teach. If you’re great at building stable relationships, you might create a relationships course. If you’re an ecommerce expert, you might teach a course about dropshipping. There’s no limit to what you can teach. You can also niche down within an industry to teach courses about specific subtopics. For example, instead of teaching public relations you might teach a course about growing your blog traffic.
