Everything I know about storytelling I learned from TV or from TV writers. That’s not really true, but it sounds good. That’s another lesson: lie your face off if it makes a good story.
Thanks to Happy Days, we have the delightful “jumping the shark” in our lexicon. It’s a fun little phrase to break out when you want to sound cool. It’s also a prescription for what not to do with your story/franchise/reputation. I will note, however, that were I to ever encounter a real shark, I would jump that mofo without hesitation.
