Ha, ha! keep time: how sour sweet music is,
When time is broke and no proportion kept!
So is it in the music of men’s lives.
And here have I the daintiness of ear
To cheque time broke in a disorder’d string;
But for the concord of my state and time
Had not an ear to hear my true time broke.
I wasted time, and now doth time waste me;
For now hath time made me his numbering clock:
My thoughts are minutes; and with sighs they jar
Their watches on unto mine eyes, the outward watch,
Whereto my finger, like a dial’s point,
Is pointing still, in cleansing them from tears.

William Shakespeare
The life and death of Richard the Second
Act 5, Scene 5
