That said, I don't really know how to improve poetry. People generally complain about how it scans, which I don't know what I'm supposed to do about - as far as I can see, each line has the requisite number of syllables and it kind of flows nicely.
To give some context, have a non-depressive poem that I've written in prior times. It's not one that I currently believe in - or rather I believe it, but am in the position of one of the people blaming luck than the smug git who wrote the poem. (I'm sure there's an appropriate proverb here, but the only one that I can think of is "What's sauce for the goose is sauce for the gander" - which isn't quite there.) Comments on scansion appreciated ;).
Since I was much younger, I've stood every test
with routine words ringing - "Best wishes, good luck!"
As if lacking these I could not do my best,
without fortune's guidance I'd surely be stuck -
in fate's rocks and minefields, past which luck's wind blows,
this whimsical, unseen, intangible force,
and I've often wondered how fortune's wind knows
which actions to hinder, destroy or endorse.
Or is there a lady? - Is luck a mere ruse
used freely by those who are lacking success?
They blame rather luck than their own lack of muse
and help themselves never - this I must confess
because I am clear that my good luck's a sham;
the harder I'm working, the luckier I am.
