It’s been 17 years since Larry McMurtry won his Pulitzer. He admits he’s not been in top form for some time now. That doesn’t stop him from writing. “He allots only 120 hours of writing time to every novel now, a breakneck pace even for a prolific writer like McMurtry, who also revises his first drafts more lightly than most writers. In his autobiographical ‘Walter Benjamin at the Dairy Queen,’ he revealed two things, one intentional, one not: He considers himself only a shadow of what he once was, the greatest western novelist of his generation. The second, unintentional revelation? His nonfiction of the past decade has far surpassed his fiction.”
