3. Don't Rely On Others To Do Your Work For You (It's A Wonderful Life, Jurassic Park, The Hunter)
If only a protagonist could be everywhere at once (or antagonist for that matter). But as Multiplicity shows us, for a protagonist's personal appeal to work, it has to be focused on one place at a time. Yet tragically, many protagonists' problems, especially in the world of business, develop from this very requirement. George Bailey is pretty much the most beloved man in town, but the biggest mistake of his life was giving key responsibility to his lovable but flawed Uncle Billy, who winds up loses everythingnot for himself, but for the poor, one-we-identify-with George. Similarly, John Hammond is a jolly old man with a cool cane who loves cloning things, but unfortunately his cloning of himself only went as far as the orientation video and he had no time to go to a fancy computerin' school to learn about computerin'. So he hired Dennis Nedry, a man who knew exactly what he was doing when he destroyed Hammond's completely harmless dream for his own ends. And in The Hunter, Red Leaf hired an archetypal cold man with a conscience to hunt down the last Tasmanian tiger. What did Red Leaf think would happen? The clear message behind these movies is that allocating responsibility to other people is a sure path to Pottersville.
