HOW oft does passion's grasp destroy
  The pleasure that it strives to gain!
How soon the thoughtless course of joy
  Is doomed to terminate in pain!

When Prudence would thy steps delay,
  She but restrains to make thee blest;
Whate’er from joy she lops away
  But heightens and secures the rest.

Wouldst thou a trembling flame expand
  That hastens in the lamp to die?
With careful touch, with sparing hand,
  The feeding stream of life supply.

But if thy flask profusely sheds
  A rushing torrent o’er the blaze,
Swift round the sinking flame it spreads,
  And kills the fire it fain would raise.
