When you measure hourly income you have to include all the time spent researching and creating your content. That $50 is most likely more like $5. If I'm reading this correctly, the $50 is the total you made, not the hourly amount.
I'm a freelance writer and I track my time differently. I bill at $75/hour with a one hour minimum. If a writing project takes me 20 minutes, I'm really averaging $225/hour. Conversely, if it takes me three hours I'm only making $25/hour. The goal is to always beat my rate. Btw, my average work week is about 15 hours and I make somewhere around a thousand a week, all from recurring clients, so I don't spend a lot of time hunting down new business. This is all possible because I established myself as a subject matter expert on several subjects. I am older and have a lot of experience so I'm not a beginner but set your sights higher- it's out there. M
