It can be hard, Mr. Zu, but I have a bit of advice for you anyways... when you can't write poetry, try reading it? Study some classic poets of old, find one you like, learn how he or she wrote poetry and try to see from that perspective. It's not copying. It's developing your technique.
I think writer's block tends to be a result of our uncertainty with the actual process of writing, as in we forget the steps necessary...
Start taking notes on your thoughts. Eventually you'll start taking notes in similies, metaphors, maybe even meter and rhyme. You'll even start seeing your tiny observations meld together in patterns.
Draw out those patterns and you'll have a poem. That's how I do it sometimes, anyways...
This poem is neat, I especially like the start and especially dislike the ending. You could have gone full-circle and given it more specific meaning than a vague shrugging three words that you left it off with.
At any rate, thanks for sharing with the Sanctuary bunch, m'friend.
Faith is a fine invention
When gentlemen can see
But microscopes are prudent
In an emergency.
