5. Robocop
(Lesson: Don't Do Coke with Hookers After a Major Career Boost) 
Sure, Robocop is mostly about a guy encased in tin upholding the law. But it's also about daring ambition in the corporate world, and to the point of fault. Yes, I'm talking about Bob Morton. Bob's the man with the plan, the guy who steps in when Dick Jones' ED-209 robot shoots up the boardroom and kills one of the suits. When preparation meets opportunity, there is no ceiling, and this mishap gives Morton the pause he needs to feed the Old Man who heads the corporation his Robocop program. (Yes, the old man is listed as the "Old Man" in the credits). But Bob messes up because he starts partying too soon after realizing his genius. This is all subplot stuff, but to get at the lesson, you need to realize that Bob's directly linked to Prometheus. He's the guy who stole fire from the gods to give to the humans, and therefore he's got to be punished. That's why Dick Jones sends Clarence Boddiker to shoot him in the knees and blow him to smithereens with a grenade. Had Morton been at the police precinct oiling the gears of his creation instead of snorting cocaine off the bosoms of prostitutes, he would have had Robocop to protect. So the next time you invent something awesome, don't celebrate until you know for certain that your enemies cannot hurt you.
