"Only the Dance is Sure"...help?

It's William Carlos Williams' poem "The Dance"...not the Brueghel one. I've read this poem over and over. I want to write about it for a literature course I'm taking, but I can't find any thoughtful angles on it other than that it merely represents "life." Any thoughts?

"The Dance"

When the snow falls the flakes
spin upon the long axis
that concerns them most intimately
two and two to make a dance

the mind dances with itself
taking you by the hand,
your lover follows
there are always two,

yourself and the other,
the point of your shoe setting the pace,
if you break away and run
the dance is over

Breathlessly you will take
another partner
better or worse who will keep
at your side, at your stops

whirls and glides until he too
leaves off
on his way down as if
there were another direction

gayer, more carefree
spinning face to face but always down
with each other secure
only in each other's arms

But only the dance is sure!
make it your own.
Who can tell
what is to come of it?

in the woods of your
own nature whatever
twig interposes, and bare twigs
have an actuality of their own

this flurry of the storm
that holds us,
plays with us and discards us
dancing, dancing as may be credible.

The dance is life you sometimes move at a slow pace like a slowdance when you fall in love and sometimes their are times when you move at a fast pace like your excited mess up and the dance is over (just like life) the point of the shoe leads the way (your soul) everything can be mirrored to be an example of life just make it all one extended metaphor at least thats my take on it
