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
