You can lead a horse to water but you can’t make it drink.
You can’t make an omelet without breaking eggs.
You can say that again
Your Guess Is as Good as Mine
You can’t unscramble a scrambled egg.
You can catch more flies with honey than with vinegar.
Your name is mud
You can’t always get what you want.
You can’t teach an old dog new tricks.
You can’t have your cake and eat it too.
