This expression comes from an observation attributed to Ralph Waldo Emerson in 1889 , though also claimed by Elbert Hubbard : ‘If a man write a better book, preach a better sermon, or make a better mousetrap than his neighbour, tho' he build his house in the woods, the world will make a beaten path to his door’.
