If It Ain't Broke Don't Fix It──別沒事找事做

** do not try to improve or meddle with something that's functioning adequately~~ 別沒事找事做；不破不修；未損

勿修，能用莫換；勸人不要破壞現狀~~ let s-

leeping dogs lie // leave/let well enough alone // never change a running system // don't change a winning team // perfect/best is the enemy of the good

!! The origin is unknown, but the idea could be in an Aesop’s Greek fable: the fox who refused the hedgehog’s offer to remove its ticks said: "lest by removing these, which are full, other hungry ones will come."

（起源未知，但這個想法可能來自伊索寓言：狐狸拒絕刺猬幫他去除蜱蟲，說：“免得去除這些已經吃飽的，其他飢餓的蜱蟲便會來。”）

!! The phrase was the motto of Sir Robert Walpole, prime minister ofEngland from 1715 to 1717 and again from 1721 to 1742.

（這句話是一七一五至一七一七年、一七二一至一七四二年英國首相羅伯特 · 沃波爾爵士的座右銘。）

Bert Lance, Director of the Office of Management and Budget under President Jimmy Carter, is credited as having popularized this phrase in the May 1977 issue of a magazine Nation’s Business.

（卡特總統的管理和預算辦公室主任伯特 · 蘭斯於一九七七年五月出版的《國家商業》雜誌上，使用並普及了這句短語。）

>> Only one of the twenty fluorescent tubes is broken, we aren’t replacing the whole system. If it ain’t broke, don’t fix it.

（二十支熒光燈管中只有一支壞了，我們不會更換整個系統，別沒事找事做。）

>> This door lock is very dilapidated, however, it can still work; if it ain’t broke, don’t fix it.

（這個門鎖已殘舊不堪，但仍能用，不破不修了。）
