This is a poem in the form called Pantoum, from Malay

Up a Ladder of Lightbulbs

they go up a ladder of lightbulbs
an obvious and easy route
not often is it taken
because lightbulbs break when stepped on

an obvious and easy route
powerful but delicate lights
because lightbulbs break when stepped on
shattered minds are useless

powerful but delicate lights
twinkle in the high places
shattered minds are useless
those that can't twinkle anymore

twinkle in high places
gleaming, glittering minds for great things
those that can't twinkle anymore
shattered so others can go up

gleaming, glittering minds for great things
not often is it taken
shattered so others can go up
the ambitious go up a ladder of lightbulbs
