“Stars, hide your fires; Let not light see my black and deep desires.” 
― William Shakespeare, Macbeth

“Out, out, brief candle! Life’s but a walking shadow, a poor player that struts and frets his hour upon the stage and is heard no more. It is a tale told by an idiot, full of sound and fury, signifying nothing.” 
― William Shakespeare, Macbeth

“I am in blood
Stepp’d in so far that, should I wade no more,
Returning were as tedious as go o’er.” 
― William Shakespeare, Macbeth
