Build a better mousetrap, and the world will beat a path to your door

"Build a better mousetrap, and the world will beat a path to your door" is a metaphor about the power of innovation.

[1][2] The epigram as known today, which specifies "mousetrap", probably also originated with Emerson, although the evidence for this is indirect.

[3] In February 1855, Emerson wrote in his journal, under the heading "Common Fame": If a man has good corn or wood, or boards, or pigs, to sell, or can make better chairs or knives, crucibles or church organs, than anybody else, you will find a broad hard-beaten road to his house, though it be in the woods.

[4] In May 1882, a month after his death, the following quotation was attributed (with no date or source) to Emerson by The Cincinnati Enquirer under the heading "The Value of Good Work": If a man can write a better book, preach a better sermon or make a better mouse-trap than his neighbors, though he builds his house in the woods, the world will make a beaten path to his door.Researchers believe it likely that Emerson used a modified version of the theme from his journal in a lecture given at some point after 1855, with the word "mouse-trap" inserted in place of one of the other example products.

[5] Statistics suggest that it is frequently taken literally, with more than 4,400 patents issued by the United States Patent and Trademark Office for new mousetraps, with thousands more unsuccessful applicants, making them the "most frequently invented device in U.S.
