“If your reason to have a blog is because a content marketer said to, or because your competition has one, or because you figured out how to install WordPress on your hosted web service, these are not good enough reasons. Blogging is not climbing Everest; “Because I can” does not constitute a good reason.
More than likely, you blog because you have been convinced that the more content you generate, the more sales you will ultimately create. I’m not going to argue with that idea, but I will quibble with your execution.”
