Do not let your passion for a person become too strong, for it may soon burn itself out. Mild affection is more likely to be long-lived. In Shakespeare’s Romeo and Juliet, Father Laurence advises Romeo:
These violent delights have violent ends,
And in their triumph die; like fire and powder
Which as they kiss consume: the sweetest honey
Is loathsome in his own deliciousness,
And in the taste confounds the appetite:
Therefore love moderately; long love doth so
Too swift arrives as tardy as too slow.
