The 4 Pillars of Good Writing

As a writer, you're in the experience business. Your job is to show your readers a good time: to intrigue and inspire, to enlighten and engross, to please and provoke. You're a dealer in fascinating ideas and satisfying arguments, a purveyor of a-ha moments and epiphanies.

Outside of school, you're writing for readers, not graders. Real-world audiences are looking for a good experience, not a "correct" performance.
