Of toil you say a moderate share <br />In each pursuit should rise, <br />Too much may make our hearts despair, <br />Too little we despise: <br />In every common case I own <br />The justness of the thought, <br />A fly may be too quickly won, <br />The world too dearly bought. <br />Not so in Love; his charms depend <br />Upon himself alone, <br />No foreign circumstance can lend <br />A lustre to his throne: <br />Though gain'd without one care, his joys <br />High-valued must remain, <br />Are cheaply purchas'd when the prize <br />Of Industry and care.<br /><br />Henry James Pye<br /><br />http://www.poemhunter.com/poem/verses-addressed-to-a-lady/
