Passing and The Not

So what is the problem
with failing?
Reckon it as red stains
upon some important papers.

But who is there
to give a grading
this time round
when its no exam?

Experience is a hard teacher
they say,
who gives the test first
and the lesson later.

I'll rather listen
to the person who didn't succeed
and not the one who boast
of never failing.

For it is a good chance
that he has never tried hard enough.
And that failure,
is a much better teacher.

If you are wrong
admit it,
even if you are,
much more senior.

And make yourself
the best lesson
that can be taught
to any other.
