when will my candle burn out?

"To-morrow, and to-morrow, and to-morrow,

Creeps in this petty pace from day to day,

To the last syllable of recorded time;

And all out 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
