Ernest Hemingway said this quote
“ The blue-backed notebooks, the two pencils and the pencil sharpener (a pocket knife was too wasteful) the marble-topped tables, the smell of early morning, sweeping out and mopping, and luck were all you needed. For luck you carried a horse chestnut and a rabbit's foot in your right pocket. The fur had been worn off the rabbit's foot long ago and the bones and the sinews were polished by wear. The claws scratched in the lining of your pocket and you knew your luck was still there. ”
