According to a different source, this question refers to the poem "To His Coy Mistress" by Andrew Marvell.
In this poem, the author talks about the ephemeral nature of life and the need to live each day to the fullest. However, he does so in several different ways.
Marvell presents three related arguments. The first arguments is introduced with the lines: "Had we but World enough, and Time,/This coyness Lady were no crime." The poem argues that, if time was unlimited, there would be no need to rush our love, or indeed, any of our decisions. We would have unlimited time to do anything, and to take as long as we want doing it. In this case, there would be nothing wrong with postponing satisfaction.
The author introduces the second idea with the lines: "But at my back I always hear/Times winged chariot hurrying near:/And yonder all before us lye/Desarts of vast Eternity." In these lines, the author provides contrast with the first section. He tells us that, in reality, we do not have unlimited time. We are always moving towards death, and end. And that refusing to enjoy life's pleasures will only result in us missing out on everything the world has to offer.
The final idea of the poem comes with the lines "Now therefore, while the youthful hew/Sits on thy skin like morning dew." In this last section, the author urges the "coy mistress" to follow her impulses, seize the day, and live life the way she wants to while she is young, regardless of the limitations society imposes on her.
