Shakespeare: Tomorrow and tomorrow and tomorrow

SEYTON:  The Queen, my lord, is dead.
MACBETH:  She should have died hereafter.
There would have been a time for such a word.
Tomorrow and tomorrow and tomorrow
Creeps in this petty pace from day to day
To the last syllable of recorded time,
And all our yesterdays have lighted fools
The way to dusty death. Out, out, brief candle!
Life’s but a walking shadow, a poor player
That struts and frets his hour upon the stage
And then is heard no more. It is a tale
Told by an idiot, full of sound and fury,
Signifying nothing.

• William Shakespeare, Macbeth (1606)
