The quest is necessary to set the stage for an epiphany. You can’t just say, “I was sitting around the house in my underwear trying to think of a business to start, and decided to make a food product that tastes good.” The particular quest here is carefully chosen to appeal to the company’s target market. It would be ineffective to say, “I had been slaving away on my food science dissertation for months. I had finally finished the last edit, when I had an epiphany…” It needs to be the same sort of activity that the target market dreams of doing.
After setting the stage, the story delivers the punch line. The trivial, obvious idea presented as novel, original, and ingenious. Make food that tastes good. If the idea was an epiphany for him, I’m just glad I never ate at his bakery. But the more trivial and obvious the idea is, the better the story sounds. Ideas like “make food that tastes good,” or “write software that’s powerful yet easy to use,” or “design clothes that make people look their best,” are powerful positive messages. And the implicit negative message about the competition stays in the reader’s mind too.
