If writer’s block truly exists, then, in my humble opinion, it is nothing more than missing inspiration. If I’m inspired, nothing can stop me from writing.
Inspiration is the “Right mood” for the intercourse between the writer and the page.
It’s the thing that sends you scurrying for the candles and wine glasses, makes you light the fireplace and get that comforter out of the chest in the front hall, open the chocolates and put on the stereo … so to speak.
