"Methought I heard a voice cry, Sleep no more!Macbeth does murder sleep, - the innocent sleep;Sleep that knits up the ravell'd sleave of care, The death of each day's life, sore labour's bath,Balm of hurt minds, great nature's second course, Chief nourisher in life's feast."
"What's done cannot be undone."
"...Who could refrain, That had a heart to love, and in that heart Courage to make love known?"
"Life ... is a taleTold by an idiot, full of sound and fury,Signifying nothing."
"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."
