Through blogging you give your opinion on any topic you choose. This way you gain followers who enjoy your content and will value what you have to say. The best part is that you can create a blog on anything you are passionate about. Once you create a blog you can monetize it by hosting ads, or offering free content in exchange for email subscribers that you can later sell to.
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.
