““Productivity, I discovered, is a broad church that tolerates many creeds. Some successful academics write daily, others sporadically; some at home, others at work; some on trains or airplanes or during children’s sports practice, others in distraction-free environments; some on a word processor, others in longhand or using voice-recognition software; some whenever they have a few minutes free, others only when they have cleared hours or days of uninterrupted time. Some map out a detailed topic outline before they start writing; others write to discover what they have to say.””
