Roulette

Norton lived for the excitement of roulette. Fortunes could rise and fall on a dime. That was his life story. One minute he's eating a grilled cheese sandwich. Then he's choking. He grabs the bottle of water from a stranger sitting across from him and drinks until his throat is clear.
He apologized, but the man seemed unfazed. It happens to everyone, he said.
Then he took out a book from his knapsack and offered it to Norton. It was his own book, a collection of flash fiction. Perhaps this book can change your life, he said.
Norton took the book and read it. He was so inspired, he decided to become a writer. Next day he brought his notebook to the coffee shop and started a short story. Three pages in, he took a bite of his chicken teriyaki sandwich, choked and keeled over before he could drink anything. His heirs kept that fragment and every anniversary of his death, they took it out and read it by candlelight.
