Tomorrow and tomorrow and tomorrow

In the words of William Shakespeare:

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.

 — Macbeth (Act 5, Scene 5, excerpt)
