An occupational hazard

I like to write poems
but struggle with rhyming—
to do that, you need to have
rhythm and timing meter.
 
Some knowledge of synonyms  
won't go amiss—
so if that word doesn't fit,
you can use this another.
 
It pays to make sure  
that each rhyming word's strong  
because if they're not equal,
the poem sounds wrong contrived.
 
I find that by rhyming
my poems sound flimsy,
although I appreciate  
humour and whimsy lightheartedness
 
Perhaps I should stick
to my usual style,
because trying to rhyme
always takes quite a while long time.
 
So it's out with constraints,
the word 'extravaganza',
and rhyming schemes...
because this is my last stanza verse.
