Edna St. Vincent Millay Quote

Time does not forfeit; Time does not abstain;
The future in one fist, he eats the past.
I know this; yet again and yet again
I try to hold the present, make it last
One moment, that the simple great be slain
Not unperceived. No hope — Time eats so fast.

Huntsman, What Quarry? (1939)
