Man should not be perfect.
Man cannot be perfect.
For to be perfect is to be god,
and man is not god.
We may strive for greatness,
to do the impossible and
to never fail.
But that's what humans do, because
to do the impossible implies it could
not be done before, if
one is perfect nothing is impossible.
To strive to never fail, suggests
that one can fail, and
to the perfect, failing
is not possible.
