Besides the obligations that I listed above that stand in my way of spending more time writing, there is always the peristant thoughts that readers will dislike my writing or that I'm wasting their time. Awhile back I ran across a line in Zinsser's On Writing Well that speaks to this:
"You are writing for yourself, don't try and visualize the mass audience."
I'm going to take Zinsser's advice. I'm going to treat this as a process of self discovery and see where it takes me.
