Don’t bite the hand that feeds you.
Don’t put all your eggs in one basket.
Don’t count your chickens before they hatch.
Discretion is the better part of valor.
Don’t cast pearls before swine.
Don’t blow your own trumpet.
Don’t cross a bridge until you come to it.
Don’t judge a book by its cover.
Don’t kill the goose that lays the golden eggs.
Don’t bite off more than you can chew.
