This is a great list! Some of these I have never thought of for the stay at home moms (and stay at home dads 😉 ) out there. I have done a lot of research on different ways to make some income and I am always amazed at the ideas I still routinely find. You mentioned working for Amazon. I know Amazon has a platform that offers some micro jobs you can do as well. They pay small amounts but if you do a lot they can add up! I also like Uber! But only for driving during the day. I wouldn’t suggest driving for Uber at night.
So many people dream of writing a book, but never go through with it. Yet no matter what, I’m sure you have experience and value you could give through writing a book. By packaging your skills and knowledge into a downloadable eBook that helps people learn a skill, advance their careers, or start a businesses, you can change someone’s life and even make good money online. You'll just need to employ an easy tool like Sellfy in order to quickly sell PDF files (like an eBook) to your readers.
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
