nothing ventured, nothing gained

If you won’t take a chance you can’t expect to achieve anything. There are two older proverbial forms of this expression, nothing (nought) venture, nothing (nought) have, stated by Chaucer (ca. 1374), and nothing venture, nothing win, stated by William Caxton about a century later. The modern form appears in Thomas Heywood’s play Captives (1624): “I see here that nought venters, nothinge gaynes.” It has been repeated in numerous languages ever since. Another, seemingly modern form is no pain, no gain, today frequently uttered by coaches, trainers, and physical therapists. Versions of this date from the early seventeenth century—“Pain is forgotten where gain follows” appeared in several early proverb collections—and the current rhyming cliché was proverbial by the mid-nineteenth century.
