Lack of confidence is one of the reason why bloggers don’t publish their posts. Especially, in this age of information overload, we tend to gather much information without much effort about the needed topic or content interesting to us but due to lack of confidence your best post has never been published yet. We all struggle with the confidence at times when it comes to hitting the publish button. I have been blogging for more than four years and I battle the same force of struggle as you do, to feel confident. I have my doubt and worries similar to yours.
