Character cannot be developed in ease and quiet. Only through experiences of trial and suffering can the soul be strengthened, vision cleared, ambition inspired and success achieved.
Okay... I'm sort of confused. My blog has to be about a certain product or service? It can't be just about anything?
Your blog CAN be about ANYTHING........but the content has to be high quality and frequently updated.
For example I intend to make a blog about the Chicago Bears soon because I am passionate about them and know a ton and would enjoy writing about them on a daily basis. My sole revenue will be through affiliate links and advertisements (all Bears related).
In order to generate significant income I will be striving for 5,000-10,000 visitors per day. (It will probably take a couple of year of solid daily blogging and some great content and features)
I think it takes years to build up a following like that, and many of them started out before vlogging became popular. I think vlogging is an easier way to build up followers.
