Writer's block. I think it can happen to anyone. Constant self-doubt. What and why and who cares what I'm writing? Is this significant? Is this drivel?
At some level it is. Absolutely. Drivel.
But one must start somewhere, and moving from the vast possibilities of blank sheet of paper (or a blank blog screen) to a specific topic of relevance can seem insurmountable. It's that first step that matters.
As you can tell, I'm suffering from this now ;). How self-indulgent.
