Unthrifty loveliness, why dost thou spend <br />Upon thy self thy beauty's legacy? <br />Nature's bequest gives nothing, but doth lend, <br />And being frank she lends to those are free. <br />Then, beauteous niggard why dost thou abuse, <br />The bounteous largess given thee to give? <br />Profitless usurer, why dost thou use <br />So great a sum of sums yet canst not live? <br />For having traffic with thyself alone, <br />Thou of thyself thy sweet self dost deceive. <br />Then how when nature calls thee to be gone, <br />What acceptable audit canst thou leave? <br /> Thy unused beauty must be tombed with thee, <br /> Which usèd, lives th' executor to be.<br /><br />William Shakespeare<br /><br />http://www.poemhunter.com/poem/sonnet-4-unthrifty-loveliness-why-dost-thou-spen/
