I have a strong belief from the Institute I was educated from, that it is our individual that determines how well we are going to be. Blog are just writing and sharing of info, but we can also make something from it. It is like all 7.2 billion are speaking and we are listening.
Depending on your niche, it is saturated. You have to find a niche that isn’t but many of those aren’t as lucrative if you plan on writing as a career.
