Even Unpublished Blog Posts can be Beneficial
I, and many other artists I know, have probably hundreds of drawings hidden in sketchbooks that won't have anyone else's eyes on them, because all of that work that you haven't shown anyone else still contributes to your craft. In a way, I think this can kind of apply to any blog posts that you make, because regardless of whether or not you decide to share them, the act of writing them can still allow you to clarify your thoughts on a certain topic and get some momentum going.
Now, I'm not necessarily saying this as an excuse to not show your work at all, or to further procrastinate if you've thought about posting your creations or blog posts online. But I do think that there is a benefit to going through the process of trying out your ideas, even if in the end you decide that they're better left unpublished. If you pressure yourself into publishing whatever you write every single time you start writing, you might end up making your procrastination worse, since you'll be too caught up in trying to figure out what kinds of blog posts other people will like instead of just figuring out whatever it is that you're genuinely interested in creating.
So, know that all of those posts that are sitting there, unpublished, that might only be seen by you, are still an important part of the process!
