When you’re having trouble writing, get up, go out, take a walk in the street. You will discover that certain streets exist precisely for this purpose. Once, I saw a man—homeless by the look of him—digging through the trash. He pulled out a couple of sheets of newspaper, examined them, and threw them back. Fishing deeper, he hauled up a magazine, squinted at the cover, and threw it back. Shit, he said, walking away. There ain’t nothing to read in these fucking cans anymore.
