Poetry tidbit, stuck in my head

I've been turning this poem by Adrienne Rich over in my head the past few days. It does well to describe what been in my head:

Transcendental Etude
Adrienne Rich

No one ever told us we had to study our lives,
make of our lives a study, as if learning natural history
or music, that we should begin
with the simple exercises first
and slowly go on trying
the hard ones, practicing till strength
and accuracy became one with the daring
to leap into transcendence, take the chance
of breaking down the wild arpeggio
or faulting the full sentence of the fugue.
--And in fact we can't live like that: we take on
everything at once before we've even begun
to read or mark time, we're forced to begin
in the midst of the hard movement,
the one already sounding as we are born.
