Ambition

A strong desire to achieve something, especially success, power, or a special goal. It often includes the willingness to work hard for it.

From Middle English *ambicioun*, via Old French, from Latin *ambītiō* (“a going around, striving for favor”), from *ambīre* (“to go around”), originally describing candidates going around seeking votes. It shifted from “campaigning for office” to “strong desire for achievement.”
