Wow! What an awesome list! My favorite is the stock photography because I love photography. I have had some success there, particularly with one photo I make some decent income from.

Who doesn’t like some down and dirty affiliate fees?!  Especially if you realize it can be even easier to make money this way than with an ebook.  After all, you simply need to concentrate on pumping out some content for your own site and getting the traffic in, often via Google or social media.  Unsurprisingly, most people can enjoy their first affiliate sale within 30 days of starting a blog.  Continue reading >
