Some artists I know are like Jack Kerouac - creative but heavily dependent on other people to get their work made & out, and also have a healthy self-destructive streak in them.
Others, specially a lot of DIY indie filmmakers - are like Lawrence Ferlinghetti - a peer of Kerouac - but a much more stable type of artist who not only creates but also organizes (helps others create), and engages in business (Ferlinghetti opened San Francisco's now famous City Lights Bookstore & published works by fellow artists such as Allen Ginsberg).
Both kinds of artists are cool, but the Ferlinghetti kind probably lead longer, happier, more productive lives (to some those are important things).
The practicality of their two lives aside, I am a huge fan of Kerouac's On The Road & several other works (The Scripture of the Golden Eternity, Desolation Angel, etc.) - fun & useful things to read when thinking about writing a script or anything else for that matter - 'cause at his best Kerouac makes writing look fun & exciting. Here's Kerouac's list of thirty "essentials" for writing, with an intro (from the Wikipedia page):
"He [Kerouac] would go on for hours, often drunk, to friends and strangers about his method. Allen Ginsberg, initially unimpressed, would later be one of its great proponents, and indeed, he was apparently influenced by Kerouac's free flowing prose method of writing in the composition of his masterpiece "Howl". It was at about the time that Kerouac wrote The Subterraneans that he was approached by Ginsberg and others to formally explicate exactly how he wrote it, how he did Spontaneous Prose. Among the writings he set down specifically about his Spontaneous Prose method, the most concise would be Belief and Technique for Modern Prose, a list of thirty "essentials."
