Th' expense of spirit in a waste of shame <br />Is lust in action; and till action, lust <br />Is perjur'd, murd'rous, bloody, full of blame, <br />Savage, extreme, rude, cruel, not to trust; <br />Enjoy'd no sooner but despised straight; <br />Past reason hunted; and, no sooner had, <br />Past reason hated, as a swallow'd bait, <br />On purpose laid to make the taker mad: <br />Mad in pursuit, and in possession so; <br />Had, having, and in quest to have, extreme; <br />A bliss in proof, and prov'd, a very woe; <br />Before, a joy propos'd; behind, a dream. <br />All this the world well knows; yet none knows well <br />To shun the heaven that leads men to this hell.<br /><br />William Shakespeare<br /><br />http://www.poemhunter.com/poem/sonnet-129/
