David previously wrote his comic book scripts using the Marvel Method, but due to his tendency to overplot, as during his collaboration with McFarlane on "The Incredible Hulk", he switched to the full script method, which he continues to use . He has stated that he prefers to plot his comics stories in six-month arcs. He has stated that when he works on a particular title, he always does so with a particular person or group of people in mind to which he dedicates it, explaining that he wrote "Supergirl" for his daughters, "Young Justice" for a son he might one day have and "The Incredible Hulk" for his first wife, Myra, who first urged him to accept the job of writing that book. David has further explained that the events of his own life are sometimes reflected in his work, as when, for example, following the breakup of his first marriage, the direction of "The Incredible Hulk" faltered, with the Hulk wandering the world aimlessly, hopelessly looking to be loved.
