Common App Personal Essay Question

Okay so I applied early to 4 schools and I used an essay that talked about my interest in hurricanes (answering the prompt about a specific interest). Since I plan on applying to Cornell, Columbia, Princeton and Duke i want to do another essay that shows off more of my personality. I was thinking about doing it about and anecdote but i dont think i could answer any prompt with it. Is it worse to submit an essay of my choice that doesn’t answer a prompt per say?

plz help lol
