Writing is an emotionally draining and solitary business. You spend hour upon hour alone with your thoughts and fantasies, doing your best to order, re-order and transform them into coherent stories people will want to read. Like any other endeavor, you have good days and bad days. Sometimes you feel exhilarated; at other times you feel frustrated and exhausted. As they say, it goes with the territory.
My wife has noticed what she’s called “carryover” from a day’s writing. She can tell if I’ve been working on an intense scene or chapter—one with plenty of action or anger, or one brimming with life-altering (even murderous) conflicts between characters. She picks up on the energy writing has generated within me. It doesn’t simply dissipate when the day’s writing is finished. It carries over for a while.
