“Whenever man comes up with a better mousetrap, nature immediately comes up with a better mouse.”
“Better to be a mouse behind the wainscoting, nibbling at the wires. Better to be a spider, high up under the eaves, spinning its web.”
“... the object of learning was not to build a better mousetrap but to ask a better question.”
“Chins up, stick it out, better times will come.”
“If poetry comes not as naturally as the leaves to a tree it had better not come at all.”
“If a man can write a better book, preach a better sermon, or make a better mousetrap than his neighbor, though he build his house in the woods, the world will make a beaten path to his door.”
