When it's over, I want to say all my life
I was a bride married to amazement.
I was the bridegroom, taking the world into my arms.

When it's over, I don't want to wonder
if I have made of my life something particular, and real.

I don't want to find myself sighing and frightened,
or full of argument.

I don't want to end up simply having visited this world.

-- Mary Oliver

The full Mary Oliver poem is called "When Death Comes":

"I don't want to end up simply having visited this world."

Nature ... 

You plan to do nature with your one wild and precious life?

I am not simply visiting this world – I am not planing to do nature... I am Nature ...

By definition everyone is nature. 

Do you see a lot of that definition?

Yes I do.

Given your above:

You plan to do nature with your one wild and precious life?

and

By definition everyone is nature. 

So were you asking if I "plan to do everyone?"  Meh, seemed a reasonable ambition for a certain wild age, not too long ago...

...but I'm married now and with a baby daughter: it's a life less wild, but certainly more precious...

Ha! You can do anything but you cannot do everything.
