Before we get started, I'd like to give a special shout-out to all of the authors who manage to balance original concepts, characterizations, and plots with clichés. It is truly an art and something we all aspire to.
Without further ado, here's Part One of Writing Clichés:
The Wealthiest Man Alive: Billionaire
Instantaneous Sparkage: Romantic Comedies
Toxicity and Electricity: Dark Romance
Nerds, Lockers, and Hormones: Teen Fiction
