Don't fix what's not broken.
Let sleeping dogs lie.
If it ain't broke, don't fix it.
Let sleeping dogs lie — who wants to rouse 'em?
I tell people if it aint broke don't fix it.
You don't try to fix things that aren't broken.
Let others worry about their own lives, and let the rest of us live.
Let lying dogs sleep is something I always say in reference to the Smiths.
We don’t want to break what isn’t broken trying to fix what is.
