Annie Dillard didn't wait around for inspiration. She built her days on a schedule and defended it the way you would defend a life raft, because for her the plan was the thing that kept the work moving at all.

The Direct Answer
A strict, self-imposed schedule that turned each day into steady, structured hours of writing.
She called a schedule a net for catching days in The Writing Life.

The Schedule as a Net

Dillard's most quoted idea about routine is simple. A schedule protects a writer from the chaos of a wide-open day. Left to mood and whim, the hours scatter and nothing gets built. A plan gives you a place to stand and something to hold onto while you work. She stacks up three images for it in a single breath, and each one is load-bearing.

A schedule defends from chaos and whim. It is a net for catching days. It is a scaffolding on which a worker can stand and labor with both hands at sections of time.

Annie Dillard, The Writing Life

What the Days Actually Looked Like

The routine she describes is monotonous by design. Long stretches at the desk, a bare room, few interruptions, roughly the same shape day after day after day. Dillard was honest that a day closely resembling every other day for ten or twenty years running does not obviously look like a good one. She kept it anyway, because it produced the books. Her underlying point is blunt. How you spend your days is how you spend your life, so the schedule you keep is the life you are actually living.

She also catalogs how other writers arranged their hours, and she is careful not to prescribe one correct schedule. Any workable routine, in her view, beats the drift of an unplanned day. The specific hours matter less than the fact of having them at all.

That is why she treated the routine as close to sacred. The schedule wasn't decoration or a productivity trick. It existed to make sure the writing got done whether or not she felt like writing on any given morning.
