Nothing gold can stay

I usually am not into stuff like poetry, but that poem"Nothing Gold Can Stay" really broke my heart.  It was so deep.  Well, here it is:

Nothing Gold Can Stay by Robert Frost

Nature's first green is gold,

Her hardest hue to hold,

Her early leaf's a flower;

But only so an hour.

Then leaf subsides to leaf.

So Eden sank to grief,

So dawn goes down to day

Nothing gold can stay.
