The poet Charles Bukowski would seem to be the least likely person one would turn to for career advice, but this little piece is oddly moving.

don’t be like so many writers,
don’t be like so many thousands of
people who call themselves writers,
don’t be dull and boring and
pretentious, don’t be consumed with self-
love.
the libraries of the world have
yawned themselves to
sleep
over your kind.
don’t add to that.
don’t do it.
unless it comes out of
your soul like a rocket,
unless being still would
drive you to madness or
suicide or murder,
don’t do it.
unless the sun inside you is
burning your gut,
don’t do it.
