Ben Norris shares how writing and publishing a blog can be a helpful exercise even without a large audience, something I also believe:
Deep down, I know that part of what has held me back from writing more is the feeling of shouting into the void. There is not a large reader base waiting for me to publish again, and so the pressure is less than in other areas of my life. However, throughout the course of this year, I have learned that writing is a helpful exercise for me and my mind. I do not need an audience. I am my audience. The act of processing my thoughts sufficiently to express them is healthy and productive, and requires no other validation to be worthwhile. Hopefully I can remember that.
