Good Morning, Contessa

Good morning to you, 2007. I hear they're running a poetry contest at the Best American Poetry web site (www.bestamericanpoetry.com) and I may enter. But in the mean time and all time is mean, here's a little contest for youse, contessa.
Who wrote these lines?

It lives less in the present
Than in the future always,
And less in both together
Than in the past. The present
Is too much for the senses,
Too crowding, too confusing --
Too present to imagine.

What does "It" stand for? Who wrote these lines? What is the title of the poem I am quoting? Anyone who answers "Burnt Norton" by T. S. Eliot wil be disqualified. For extra credit, disregard three of these questions and write a one-paragraph prose poem defending the proposition that "carpe diem" as a strategy will not work in "modern" times. Be sure to define "modern." Hint: it will be easier to answer if you. If you see Kay tell her. Down the slippery slope we slid. See www.slope.org for more along those lines to be read while drinking fine wines. Check out www.mipoesias.com for a trip to the moon on gossamer wings. Consider www.operationpaperback.org for a better idea for what to do with those used books of yours you can't bear to toss.
