Th' expense of spirit in a waste of shame <br />Is lust in action; and, till action, lust <br />Is perjured, murderous, bloody full of blame, <br />Savage, extreme, rude, cruel, not to trust, <br />Enjoyed no sooner but despisèd straight, <br />Past reason hunted, and no sooner had <br />Past reason hated as a swallowed 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 proved, a very woe, <br />Before a joy proposed; 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-th-expense-of-spirit-in-a-waste-of-sh/
