David has stated that he tries to block out different days and different times to work on different projects. He usually works in the morning, for example, on novels, and does comics-related work in the afternoon. Having previously used Smith Corona typewriters, he writes on a Sony Vaio desktop computer, using Microsoft Word for his comics and novel work, and Final Draft for his screenplays. When writing novels, he sometimes outlines the story, and sometimes improvises it as he is writing it. Following his stroke in December 2012, David began using DragonDictate to write. Todd McFarlane's original art for the cover of "The Incredible Hulk" #340, featuring Wolverine, which McFarlane gave to David as a gift, hangs in David's office.
