Alice Munro built a Nobel-winning body of work on an unglamorous schedule. She wrote in the mornings, seven days a week, and treated her page quota like a debt she had to repay. The habit held for decades.

The Direct Answer
She wrote every morning, seven days a week, from about eight to eleven.
A discipline she kept for years, with a page quota and a daily three-mile walk, per her 1994 Paris Review interview.

The Morning Routine

Munro described her working day plainly. She got up, had some coffee, and started writing, keeping the serious work to the early hours. In her 1994 Paris Review interview she put the window at roughly eight to eleven, seven days a week, and said she filled the rest of the day with other things unless a final draft pulled her back to the desk.

I write every morning, seven days a week. I write starting about eight o'clock and finish up around eleven.

The Quota She Owed Herself

The discipline came from a quota. Munro set herself a number of pages and called herself compulsive about hitting it. Miss a day and the pages carried over, to be made up later. She kept the same rule for exercise, walking three miles a day and making up any day she expected to skip.

She was candid that the writing itself came slowly. She filled notebooks with rough, clumsy drafting just to get something down, then hauled herself back whenever she wandered onto the wrong track. The routine wasn't there to make writing easy. It was there to make sure it happened.
