Mary Oliver, "The Fourth Sign of the Zodiac"

I know, you never intended to be in this world.
But you're in it all the same.

So why not get started immediately.

I mean, belonging to it,
There is so much to admire, to weep over.

And to write music or poems about.

Bless the feet that take you to and fro.
Bless the eyes and the listening ears.
Bless the tongue, the marvel of taste.
Bless touching.

You could live a hundred years, it's happened
Or not.
I am speaking form the fortunate platform
of many years,
none of which, I think, I ever wasted.
Do you need a prod?
Do you need a little darkness to get you going?
Let me be as urgent as a knife, then,
and remind you of Keats,
so single of purpose and thinking, for a while,
he had a lifetime.
