Ah, the Formula.
Main Character: "I don't want to be [thing] like my [predecessor], I want more! There has to be something more to life than [thing]."
Progenitor: "Offspring, you will be [thing]. I am [thing], my [progenitor] was [thing], all your ancestors were [thing], there is nothing out there for us, this is all there is."
MC: "Why?"
Progenitor: "Because... just because, okay?"
MC: "No! I refuse! I will go out and do stuff!"
Wacky hijinks ensue.
