You know you're a writer when writing is a disease. But having the disease doesn't make you any good.
I can't stop myself from writing. Being addicted to it is a skill I chose to learn, and I took specific steps, and eventually found myself dependent on the drug. I made myself an alcoholic of words. It happened by degrees, ones I chose. But now I can't undo it.
As for what it takes to turn the disease into being any good, I don't know. I'll tell you if I'm ever any good.
