William Shakespeare, Sonnet iv
Unthrifty loveliness, why dost thou spend
Upon thyself thy beauty's legacy?
Nature's bequest gives nothing, but doth lend,
4
And, being frank, she lends to those are free.
Then, beauteous niggard, why dost thou abuse
The bounteous largess given thee to give?
Profitless usurer, why dost thou use
8
So great a sum of sums, yet canst not live?
For having traffic with thyself alone,
Thou of thyself thy sweet self dost deceive.
Then how, when nature calls thee to be gone,
12
What acceptable audit canst thou leave?
The unus'd beauty must be tomb'd with thee
Which, used, lives th' executor to be.
