finish starting

i truly like to finish
before i even start
it is the easy way to go
but takes a certain art

i like to wrap up something
before i have begun
i know with such a recipe
i have already won

i champion every running race
right at the starting block
the referees are most impressed
and think i am a jock

i believe every pome
should start on its last line
this one is an exception
and that is superfine
