Kerouac developed what he called "spontaneous prose." In "Essentials of Spontaneous Prose," describing what he called "LAG IN PROCEDURE," he said, "No pause to think of proper word but the infantile pileup of scatological buildup words till satisfaction is gained, which will turn out to be a great appending rhythm to a thought and be in accordance with Great Law of timing."
Today, in your journal, do some spontaneous writing. Put pen to paper and write for 5 minutes, non-stop, no editing, no stopping.
More straight from Jack:
"Begin not from preconceived idea of what to say."
"Do not afterthink except for poetic or P. S. reasons."
