The little girl - end missing

Once upon a time
there was a little girl
waiting to take over
the whole wide world

she grew and got big
got wiser each year
and with each lesson
grew a whole new fear

what if it didn't work
if she is just to weak
what if she had already
reached her talents peak

her story is yet to be fulfilled
she is still so young
what she hasn't yet learned
she is really that strong
