You can’t always get what you want.
You can say that again
You can’t fit a round peg in a square hole.
Your Guess Is as Good as Mine
You can’t make an omelet without breaking eggs.
You can lead a horse to water but you can’t make it drink.
You can’t win them all.
You can catch more flies with honey than with vinegar.
You can’t have your cake and eat it too.
You can’t unscramble a scrambled egg.
