Michael Agger marvels at fast writers:
Christopher Hitchens composing a Slate column in 20 minutes—after a chemo session, after a "full" dinner party, late on a Sunday night. The infamously productive Trollope, who used customized paper! "He had a note pad that had been indexed to indicate intervals of 250 words," William F. Buckley told the Paris Review. "He would force himself to write 250 words per 15 minutes. Now, if at the end of 15 minutes he hadn't reached one of those little marks on his page, he would write faster." Buckley himself was a legend of speed—writing a complete book review in crosstown cabs and the like. …
Some writers are "Beethovians" who disdain outlines and notes and instead "compose rough drafts immediately to discover what they have to say." Others are "Mozartians"—cough, cough—who have been known to "delay drafting for lengthy periods of time in order to allow for extensive reflection and planning." According to [psychologist Ronald] Kellogg, perfect-first-drafters and full-steam-aheaders report the same amount of productivity. Methinks someone is lying.
Practice makes perfect, I guess. My speed-writing has become much faster since blogging.
