I'm a three-time (soon to be four-time) published author. When aspiring authors learn this, they invariably ask what word processor I use. It doesn't fucking matter! I happen to write in Emacs. I also code in Emacs, which is a nice bonus. Other people write and code in vi. Other people write in Microsoft Word and code in TextMate+ or TextEdit or some fancy web-based collaborative editor like EtherPad or Google Wave. Whatever. Picking the right text editor will not make you a better writer. Writing will make you a better writer. Writing, and editing, and publishing, and listening -- really listening -- to what people say about your writing. […] Just fucking write, then publish, then write some more. One day your writing will get featured on a site like Reddit and you'll go from 5 readers to 5000 in a matter of hours, and they'll all tell you how much your writing sucks. And most of them will be right! Learn how to respond to constructive criticism and filter out the trolls, and you can write the next great American novel in edlin.
