There were a couple of nice quotes on writing in the McPhee interview:

"The thing about writers is that, with very few exceptions, they grow slowly—very slowly. A John Updike comes along, he’s an anomaly. That’s no model, that’s a phenomenon. I sent stuff to The New Yorker when I was in college and then for ten years thereafter before they accepted something. I used to paper my wall with their rejection slips. And they were not making a mistake. Writers develop slowly. That’s what I want to say to you: don’t look at my career through the wrong end of a telescope. This is terribly important to me as a teacher of writers, of kids who want to write."

and

"On a certain scale, it does look like I do a lot. But that’s my day, all day long, sitting there wondering when I’m going to be able to get started. And the routine of doing this six days a week puts a little drop in a bucket each day, and that’s the key. Because if you put a drop in a bucket every day, after three hundred and sixty-five days, the bucket’s going to have some water in it."

Both terrific quotes. Thanks. I'll definitely include one for On Writing.
