If you're a fast typist there are many ways to make money from home by typing. Some you need experience and training others you don't. Data entry, for instance, takes very little experience; however, if you aren't fast enough you won't make any money at. Specialty transcription work (like medical) may require a degree and experience to get started.
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.
