Speaking of Evaluation

I am evaluating the purpose of my blogging. It seems to me that there are many writers out there who are far better at the craft and whose contributions are infinitely more valuable. As I search for something meaningful to do with my life, I am not convinced that this is it. I can go several days without speaking to another human being and thus it is nice to 'give voice' to my thoughts, but if this is it- if this is all my life is to contain- then it ought to be given more thought and better effort or not done at all.
