There are lots of good tips in the full interview. Some of my favorites:
. . . voice is just about finding your own past valuable, the people and
conditions you have observed, usually close to home
. . . if words get in the way of your story, you are in trouble
. . . I hate editing. I love to write, but I hate to reread my stuff
. . . I think people may be unaware of how interesting they or their friends or their family are
. . . So as much as possible, I use life itself because I'm more and more convinced that a subject matter of quality is what gives you words. The subject itself will dictate better nouns and verbes if you've got a good story
Not that the rest of the issue doesn't have some good qualities too. I enjoyed the Haruki Murakami story, Heigh-Ho, the first thing of Murakami's that I've read.
