A new graduate from the Mechanical Engineering department at Miskatonic University wants to get his career going. So he has to decide what he’s going to design first.
He decides to build an aircraft carrier.
Never mind that this is one of the most elaborate, complex pieces of machinery conceivable—the graduate has decided that he’s capable of designing and building something immensely huge and complex, just like the guys who have been doing it for thirty years.
This sounds insane, but it’s exactly what a huge number of novice writers do when starting out their careers. Instead of starting with something manageable—Ray Bradbury famously advised writing short stories for several years before even attempting a novel—new writers often decide that they’re capable of producing a twelve-volume epic saga with hundreds of characters.
