Death is the great leveler

Deeds, not words

Delays are dangerous

Desert and rewards seldom keep company

Different strokes for different folk

Diligence is the mother of good luck

Discretion is the greater part of valor

Do as I say, not as I do

Do as you would be done by

Dog that barks, doesn´t bite

Do not cast your pearls before swine

Don´t barn the door after the horse runs away

Don’t bite the hand that feeds you

Don´t count your chickens before they are hatched

Don´t cross the bridge till you come to it

Don´t cry before you are hurt

Don´t cut off your nose to spite your face

Don´t cut the bough you are standing on

Don´t halloo till you are out of the wood

Don’t hide your light under a bushel

Don’t judge a book by its cover

Don´t look a gift horse in the mouse

Don´t make a mountain out of a molehill

Don´t make yourself a mouse, or the cat will eat you

Don´t meet trouble halfway

Don´t put all your eggs on one basket

Don´t put off till tomorrow what you can do today

Don´t put the cart before the horse

Don´t tell tales out of school

Don´t throw the baby out with the bathwater

Don´t wear out your welcome

Do unto others as you would have them do unto you
