Kerouac left two short lists that read like a manifesto for writing fast and trusting your first instinct. One is the essay Essentials of Spontaneous Prose. The other is a set of thirty numbered lines called Belief and Technique for Modern Prose. Together they lay out the method behind his fastest work.

The Direct Answer
Write fast, follow the mind's flow, and hold off on revising as you go.
The method lives in two lists, Essentials of Spontaneous Prose and the thirty-line Belief and Technique for Modern Prose.

Where the Rules Came From

Kerouac wrote Essentials of Spontaneous Prose in 1953, partly to answer Allen Ginsberg and William Burroughs, who kept asking how he had written The Subterraneans in three nights. It first appeared in the Black Mountain Review in 1957. The companion piece, Belief and Technique for Modern Prose, ran in the Evergreen Review in 1959 and boiled his approach down to thirty short lines, some of them practical, some closer to prayer.

The engine under both lists is speed with honesty. Kerouac wanted the sentence to track the movement of the mind before the editing brain could step in and neaten it up. He compared it to a saxophone player blowing a phrase on one breath and ending the line when the breath gives out. That is why his prose keeps rushing forward, and why he punctuated by feel.

Blow as deep as you want to blow.

What the Lists Actually Say

Some of the thirty are hard to act on, since being told to become a 'crazy dumbsaint of the mind' only gets you so far. Plenty of them are usable. He tells you to keep secret notebooks for your own private joy, and to write in recollection and amazement for yourself before any reader enters the picture. He wants you to be in love with your life, and to trust that a true feeling will find its own form on the page.

The method also has a shape most writers can borrow without going full Beat. Kerouac called one version of it sketching: you sit in front of a scene or a memory and write down what the eye and the mind hand you, in the order they hand it over. You fix your attention on the thing itself and let the language chase the image, rather than pausing to hunt for the perfect word. It reads wild on the page, and underneath it sits a fairly disciplined act of paying attention.

There is a warning buried in the method too. Kerouac sold the idea that he never changed a word, and that was partly a pose. He revised and reworked far more than the legend admits. The real lesson under the slogans is that you draft hot and open, then come back to it later with a cooler head. A few of the thirty are pure encouragement, the kind of line you tape above a desk on a bad morning. He wants you to accept loss forever and to believe you are a genius all the time, which sounds absurd until you notice how much of writing is simply refusing to quit.

See how this fed his day-to-day habits in the full Jack Kerouac writing routine.
