Can somebody check this for mistakes?

flowers and foliage are in fresh spring bloom.
almost awaiting their certain doom.
living to die as it seems.
a pointless cycle mother nature deems.
how can something futile be so beautiful?
the birds ringing songs so musical.
something so unfair but oddly just.
because live and die everything must.
like a cruel and wonderful cycle, everything must share.
so for that nature must prepare.
for when it's done, it's done.
that's all we get.
one-shot we have wasted yet.
we still have time to undo what we have begun.
but, as i said, when it's done, it’s done.

explanation:

i’m writing a memoir and i’ve been given the great suggestion of placing a ‘sub-narrative’ within some of the chapters – sort of, what was going on with me in the grand scheme of things.

i was wondering how to format this so that it is very obvious we are stepping out the of story.

firstly is a change in font from serif to sans workable? i also use dashes for a scene change. was thinking of using a different scene-changer too.

here’s a (shortened) example:

university – or what’s known as ‘uni’ in australia – were some of the best days of my life. where else do you get to potter around in a great location, have very little responsibility, learn lots of things, do lots of things and walk out four years later with a bonus – a degree!

with my university years i had immersed myself into community of intelligent ambitious people. generally everyone had a confidence about themselves. they knew where they were going in life and weren’t threatened by others.
