Shall I, wasting in despair,
Die because a woman's fair?
Or make pale my cheeks with care,
'Cause another's rosy are?
Be she fairer than the day,
Or the flowery meads in May,
If she be not so to me,
What care I how fair she be?

The Shepherd's Resolution; reported in Bartlett's Familiar Quotations, 10th ed. (1919). Compare: "If she undervalue me, What care I how fair she be?", Sir Walter Raleigh, Poem.
