Sharpe says that you shouldn't dive into internet marketing until you decide on a niche and figure out what you're passionate about. Do you want to join the make-money-online (MMO) niche? Or do you want to engage in another niche? For example, you could sell products or online courses about blogging or search engine optimization or anything else for that matter. Keep in mind that whatever you're selling, whatever niche you're in, that you need to embed yourself there deeply.
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.
