I never identified with writers who agonize over writing. Certainly their struggles are legitimate, but that simply has not been me. I think, and I write. Then I think some more, and I edit what I wrote. It has always been a fast process. I am a fast writer.
What I did not realize until recently is that I have a limited reservoir of writing in me. It doesn't matter what I write about--I can only write a certain amount in a given period of time. This reservoir is a scarce resource from which I, currently, draw in order to write a number of things except the blog and the book.
Walking away from them was easy--too easy that it scared me a bit. I need to return to them. So I write to remind myself.
