Scholars Talk Writing: Jay Parini An Interview by Rachel Toor in the The Chronicle of Higher Education May 23, 2016

Toor: Advice for academics about writing? Parini: Everyone is different, so no single approach will fit all. But I know a few things. One: Donít stop. You have to write a lot to get better at writing. If you find that your inner critic is making it hard to write, if youíre a perfectionist, lower your standards. Write badly if you must. You can always revise, making the sentences better, the paragraphs more coherent, the whole tighter and stronger. Write every day. If you must, get up early ó I tend to get up very early and start early. An hour each day is enough. John Updike once told me that he wrote at least two pages a day. He pointed out that this gave him a minimum of 600-plus pages a year. Thatís a lot of writing to work with, revise, edit. The real work of writing, the fun work, is rewriting. So donít be fussy. Write, revise, and write some more. And donít hesitate to use those weird little gaps in the day. I often have huge luck with a spare 20 minutes. And donít fuss. Donít think you have to be at your desk in a quiet place. Thatís nice if you can get it. But Iíve learned the hard way ó raising three kids with my wife, being very busy as a teacher ó that you canít let chaos ruin a good hour of writing. I can usually find a good hour, somewhere, in my day. Often between 6 to 7 in the morning ó before the noise begins. Itís my probably superstitious belief that if you stick to your writing, it will stick to you.
