If one’s purpose for a blog is blogging itself, then writing a blog post is the most productive thing they can do.
However, if one blogs to share their experience doing something else, then blogging is a supplemental activity.
I am a filmmaker, first and foremost. And I have been quite busy giving it a go.
Alas, the irony: the busier I am as a filmmaker, the more insight I have to share, yet, the less time I have to blog!
