"You can't do it when you're busy working like everyone else, collecting a paycheck, keeping regular hours, depending on the goodwill and collegiality of customers, coworkers, bosses — if you choose employment in academia, it's no different, you still have clients and bosses to please. Avoid this gentle poison by figuring out ways you can mock the system by taking from it what it needs to give you to maintain your writing, and give it nothing back in return."
From Anis Shivani's "New Rules for Writers," specifically, Rule #4: "Seek Unemployment."
ADDED: I had a link to a book of Shivani's before. The link is corrected. There's a whole, very interesting article to read!
AND: Thanks to Instapundit for linking — "ADVICE TO WRITERS: Go John Galt?" — and getting me to notice my bad link. Perhaps the trend of the comments will change with the whole context of the quote and the cue from Glenn to think in Randian terms.
