Keeping up a blog can be hard. More complicated than many might think when they first sign up here. Especially if you are doing it as a side hustle, you've got to want to make time to write, and sometimes that can get tiring for some people.
And if you found the time to start writing and posting more regularly, and time after time, you see your work barely getting any reads, well. That can be one of the most discouraging things ever. And make it harder to continue with it as well. Some maybe haven't quit writing altogether, just maybe went to other platforms where they may hope to get more readers.
