Everyone Else is a David

All I am holding
is a pen or a paintbrush,
but I feel like I'm supposed to
re-create the Great Wall of China,
only bigger and better and with,
ya know, more pizazz?
I feel like Saul, I came in chosen
and somewhere along the line
my faith was shaken
and I built an altar
the size of a computer screen
and I sat, reflecting myself away
from my worries and potentials
until the whole world,
whose first name is Samuel,
told me I'd missed my chance.
