4. Teach Something
Do you have a special skill that others may want to learn? Aside from offering private lessons one-on-one for things like music, languages, or aerobics, the Internet has introduced a new platform for learning. There are entire websites dedicated to learning a new skill directly from professionals all over the world. Skillshare is one of the most popular sites where you can sign up to be a teacher. Classes like graphic design, photography, and marketing all tend to do pretty well. You can set your own rates and have the potential to make more money because anyone anywhere can sign up for your classes.
