"Writing a page every day gets me more than a novel per year — do the math — and there’s always 20 minutes to be found in a day, no matter what else is going on. Twenty minutes is a short enough interval that it can be claimed from a sleep or meal-break (though this shouldn’t become a habit). The secret is to do it every day, weekends included, to keep the momentum going, and to allow your thoughts to wander to your next day’s page between sessions."
