Elusive template

Life is a sequence nay you may say,

I stand with above; either work or play,

system of love,

and dirt it does shove,
struggle; pain; victory; rest; again eventual birth,

peace; happiness; joy; mirth then its dearth,

trying to judge pattern in hertz,

This was the best being expressed by fifty-five unique words.

This is my first attempt at writing a 55 fiction. Whats more special about this poem is that all the words here are used only once throughout the poem.
