"But that I know love is begun by time,
And that I see, in passages of proof,
Time qualifies the spark and fire of it.
There lives within the very flame of love
A kind of wick or snuff that will abate it,
And nothing is at a like goodness still;
For goodness, growing to a pleurisy,
Dies in his own too-much. That we would do
We should do when we would. For this 'would' changes,
And hath abatements and delays as many
As there are tongues, are hands, are accidents.
And then this 'should' is like a spendthrift sigh,
That hurts by easing."
William Shakespeare, Hamlet
