When I began writing short stories I was working four days a week, had two young children, was renovating a house and cycling around 200 miles a week. Weekends were for family. Wednesdays were my day off. Wednesdays were my writing days. I’d sit and write from when the kids went to school until they came home. Some Wednesdays I could squeeze out 3,000 words.
When I injured my spine I had to give up work. Weekdays were empty. Suddenly there were at least thirty hours to spend writing. Guess how many words I turned out in those thirty hours? 3,000!
