This is the kind of statement, true but somewhat supercilious, that seems ideal for a print magazine. Hard to imagine anyone writing something so clear-headed if they thought it could be screenshotted and shared out of context.
Odd jobs—usually copyediting, tutoring, PowerPoint, graphic design; I don’t know any writers who wait tables but probably some exist—seem like a better idea in terms of one’s intellectual independence. But these can lead to a kind of desperation. What if your writing doesn’t make it? How long can you keep this up? You have no social position outside the artistic community; you have limited funds; you call yourself a writer but your name does not appear anywhere in print. Worst of all, for every one of you, there are five or ten or fifteen others, also working on novels, who are just total fakers—they have to be, statistically speaking. Journalism at least binds you to the world of publishing in some palpable way; the odd jobs leave you indefinitely in exile. It would take a great deal of strength not to grow bitter under these circumstances, and demoralized. Your success, if it comes, might still come too late.
