If (Rudyard Kipling's)

If you can keep your head when all about you

    Are losing theirs...;

If you can trust yourself when all men doubt you,

    But make allowance for their doubting too;

If you can wait and not be tired of waiting,

    Or being lied about, don't deal in lies,

Or being hated, don't give way to hating,

    And yet don't look too good,  nor talk too wise;

If you can dream -- and not make dreams your master;

    If you can think -- and not make thoughts your aim;

If you can meet with Triumph and Disaster

    And treat those two impostors just the same;

......................................................................

If you can talk with crowds and keep your virtue,

    Or walk with kings -- nor lose the common

        touch;

If neither foes nor loving friends can hurt you;

    If all men count with you, but none too much;

If you can fill the unforgiving minute

    With sixty seconds' worth of distance run ---

Yours is [given] the Earth and everything that's in it,

    And -- what is more -- you''ll be [have become] a Man, my son!

- Rudyard Kipling
