That said, lot's of people are making extra money by publishing their own books on Amazon. For instance, my friend Bob published a few books on Amazon on how to make money blogging and has done very well. The first book provided basic tips for a small price, but his next book, Pro-Blogging Secrets, is offered at a premium price and he also has an online course.
How much will you make? I think my best month with Google AdSense was almost $5,000 over the last ten years. That amazing month blew my mind since it was actually near the beginning of my blogging journey. When you go from making zero to $5,000 in a month, that will rock your world. For me, it also got me even more excited because I knew there were other ways to monetize.
