From Brain Pickings:
Reflecting on the ritualization of creativity, Bukowski famously scoffed that “air and light and time and space have nothing to do with.” Samuel Johnson similarly contended that “a man may write at any time, if he will set himself doggedly to it.” And yet some of history’s most successful and prolific writers were women and men of religious daily routines and odd creative rituals. (Even Buk himself ended up sticking to a peculiar daily routine.)
Such strategies, it turns out, may be psychologically sound and cognitively fruitful. In the altogether illuminating 1994 volume The Psychology of Writing (public library), cognitive psychologist Roland T. Kellogg explores how work schedules, behavioral rituals, and writing environments affect the amount of time invested in trying to write and the degree to which that time is spent in a state of boredom, anxiety, or creative flow. Kellogg writes:
[There is] evidence that environments, schedules, and rituals restructure the writing process and amplify performance… The principles of memory retrieval suggest that certain practices should amplify performance. These practices encourage a state of flow rather than one of anxiety or boredom. Like strategies, these other aspects of a writer’s method may alleviate the difficulty of attentional overload. The room, time of day, or ritual selected for working may enable or even induce intense concentration or a favorable motivational or emotional state. Moreover, in accordance with encoding specificity, each of these aspects of method may trigger retrieval of ideas, facts, plans, and other relevant knowledge associated with the place, time, or frame of mind selected by the writer for work.

Kellogg surmises that writers more afflicted with the modern epidemic of anxiety tend to be more disconcerted by noisy environments. Proust and Carlyle appear to have been among those writers — the former wrote in a cork-lined room to eliminate obtrusive sounds and the latter in a noiseproof chamber to ensure absolute silence — whereas Allen Ginsberg was known for being able to write anywhere, from trains to planes to parks. What matters, Kellogg points out, are each writer’s highly subjective requirements for preserving the state of flow:
The lack of interruption in trains of thought may be the critical ingredient in an environment that enables creative flow. As long as a writer can tune out background noise, the decibel level per se may be unimportant. For some writers, the dripping of a faucet may be more disruptive than the bustle of a cafe in the heart of a city.

He also cites a 1985 study of circadian rhythms — something scientists have since explored with swelling rigor — which found that performance on intellectual tasks peaks during morning hours, whereas perceptual-motor tasks fare better in the afternoon and evening. Hemingway, in fact, intuited this from his own experience, telling George Plimpton in a rare 1989 interview:
When I am working on a book or a story I write every morning as soon after first light as possible. There is no one to disturb you and it is cool or cold and you come to your work and warm as you write. You read what you have written and, as you always stop when you know what is going to happen next, you go from there. You write until you come to a place where you still have your juice and know what will happen next and you stop and try to live through until morning when you hit it again. You have started at six in the morning, say, and may go on until noon or be through before that.
