“If it ain’t broke, don’t fix it” is the proverb of common-sense restraint — a warning against meddling with something that already works. Here is what it means, its surprisingly modern origin, how to use it, and a few sayings that share its respect for leaving well alone.
What Does “If It Ain’t Broke, Don’t Fix It” Mean?
The proverb means that you should not interfere with, change or “improve” something that is already working perfectly well, because your tinkering may only break it. It is advice about knowing when to leave things alone — directed at people who can’t resist fiddling, reorganising or upgrading systems, habits or tools that are doing their job just fine. The unspoken risk is that the attempted improvement backfires and creates a problem where there was none.
Origin of the Proverb
Unlike most proverbs, this one is genuinely modern and American. It grew out of plain Southern United States speech and was in use by around 1962, but it was made famous in May 1977 by Bert Lance, the budget director in President Jimmy Carter’s administration. Lance argued he could save the government billions if it adopted the motto, explaining: “That’s the trouble with government — fixing things that aren’t broken and not fixing things that are broken.” The phrase struck a chord and quickly became a everyday saying on both sides of the Atlantic.
