This is where the magic happens. Where you stop writing an "essay" and start creating an experience.
Your Opening is Your First Impression. Make it Count.
Please, I'm begging you, don't start with "Throughout human history..." or a dry dictionary definition. The judge's eyes will glaze over instantly. Instead, drop them into a story. Hit them with a statistic that upends their assumptions. Ask a question that they can't help but want the answer to.
Let Your Voice Shine Through
Are you writing, or are you talking to the reader? Read your draft aloud. Does it sound like a textbook, or does it sound like a passionate, intelligent human being? Use contractions (it's, you'll, that's). Vary your sentence length. Let a little of your own personality seep into the prose. Is your tone wry? Urgent? Compassionate? Let that be your fingerprint.
Weave Your Evidence Seamlessly
Don't just "quote bomb." Introduce your evidence. Weave it into your narrative. Instead of: "There is a statistic. '55% of people...'" Try: "Imagine a city where more than half the population feels unheard. That's not a hypothetical; it's the reality captured in a recent Gallup poll, which found that 55% of people..." See how the second version flows?
