Metaphor

it’s no use now to think of turning back,
    The rest of the way will be only going down.
The Long Hill ~ Sarah Teasdale

Downhill now, I've passed 
the hill's crest, heedless
even of that view.
The track though is clear -
descent's my decline;
being cavalier
with clocks has let slip
past, the years on year

There's no backtrack, no
way to make amends
only a breakthrough
where the path narrows.
Sure and unbending
I'll praise tomorrows
and the chanticleer,
daybreak's cheerful seer
