I need an English proverb for this mentioned Hindi/Urdu proverb:
Chalti ka naam gaadi hai
Literally, it means "a thing which runs is called a vehicle," but that doesn't sound good. Actually it is used in a sense that when an institute, business, something else is working smoothly but there seems a room for improvement, and whenever the boss signals for improvement, then the ones who are lazy and don't want further betterment often use this proverb " a thing which runs (just operational) is called a vehicle. (Institute, business, etc)
