A golden bit does not make the horse any better.
Faint heart never won fair lady.
Charity begins at home.
Curiosity killed the cat.
Experience is the mother of wisdom.
Desperate diseases must have desperate remedies.
The best defence is a good offense.
A liar should have a good memory.
Needs must go when the devil drives.
Don't wash your dirty linen in public; It is an ill bird that fouls its own nest.
