If It Ain’t Broke, Don’t Fix It


If it ain’t broke, don’t fix it is a phrase that means if something is functioning properly, it’s probably best to just leave it alone and not make any changes that could potentially break it.

Example: Nora was not happy with her current weight, so she finally decided to commit to a diet. Eventually, she lost several pounds and was pleased with the results. However, Nora once again wants to change her diet, but she’s worried that doing so will cause her to return to her former weight. So a friend advised her: “If it ain’t broke, don’t fix it.”

In other words, if Nora’s current diet has worked fine, then there’s no reason to change it and risk messing things up.

Synonyms/Related: leave well enough alone

The Origin Of “If It Ain’t Broke, Don’t Fix It”

Bert Lance was someone who worked for President Jimmy Carter as Director of the Office of Management and Budget in the year 1977. He is credited as being the one who popularized this phrase. He was quoted as saying “if it ain’t broke, don’t fix it” in the May 1977 issue of a magazine called Nation’s Business.

Of note, according to The Phrase Finder, there’s a Texas newspaper known as The Big Spring Herald from 1976 that also has this expression in it:

“We would agree with the old Georgia farmer who said his basic principle was ‘If it ain’t broke, don’t fix it.’ “

From what I could tell, this phrase does not appear in print before the 1970s. To me, this would suggest it originated around that time and is thus not very old. During that decade, the phrase clearly started to take off in terms of use. And today, it has become a common term to hear.
