Gah.Don't write what you know. Write what interests you. Write that which provokes your curiosity and pushes your boundaries of comfort and knowledge. Get into the minds of people you're not, understand their desires and their conflicts. Expand your empathy by creating circumstances in which you would never find yourself. Explore environments that are the antithesis of yours. Challenge the concepts of normal and acceptable. Grow as a writer and you grow as an individual.
Feed your weird.
