As to why some young screenwriters succeed while so many others do not, Paul Guay (the co-writer of "Liar Liar", "Heartbreakers" and "The Little Rascals") says, “The thing that separates more successful writers from less successful writers, the most important thing, is the perseverance.” The writer-director of "Seabiscuit", Gary Ross, adds that the term “success” is rather elusive. “There’s a great line in J.D. Salinger when he talks about writing, he says, “The ultimate question is not ‘Were you successful or weren’t you successful?’ ... The real question at the end of your days when you’re judged as a writer is, ‘Were all your stars out? ... Did you live up to your potential?”
