There is no sure foundation set on blood, No certain life achieved by others' death.

I never yet did hear, That the bruis'd heart was pierced through the ear

Love that well which thou must leave ere long.

Never play with the feelings of others, because you may win the game but the risk is that you will surely lose the person for life time

Two stars keep not their motion in one sphere.

There's nothing in this world can make me joy: Life is as tedious as a twice-told tale Vexing the dull ear of a drowsy man; And bitter shame hath spoil'd the sweet world's taste That it yields nought but shame and bitterness.

The devil can cite Scripture for his purpose. An evil soul producing holy witness Is like a villain with a smiling cheek, A goodly apple rotten at the heart. O, what a goodly outside falsehood hath!
