Blogging is just similar to article writing. If you’re writing about something you don’t know, your work will just be a total failure. Likewise, if you’re blogging about a certain topic, let’s say, love, for example, but you haven’t got a girlfriend or boyfriend since birth, you’ll never be able to write a good article about it. How can you describe a feeling that you haven’t even felt? You can’t be an effective writer if you’re writing about what you do not know.
