What the hell is "shakespearean" calm? He definitely threw in a random adjective that he hoped would sound academic. I can't believe he has a cup ring.
Writers (good ones anyway) must be calm and poised when they are writing and not let their emotions get the best of them. If a writer tried writing a novel when he's emotionally charged, it's going to sound like a rambling piece of crap. You jot down what you feel when you're angry, sad, happy, etc, and then when you've had time to recollect, you take down what you wrote and rewrite in a calm and neutral stand point. That's why most emos think they can write poetry. They think having issues is a free pass to become a writer, when in reality all they do is b*tch and wine. No structure at all.
Haha, I'm guessing Perron wasn't thinking that in his head when using Shakespeare (arguably the greatest writer of all time = very calm) as an adjective, but there is some reasoning that can be put into that statement. Getting inside of Perron's head to figure this out probably wouldn't be worth it
