+If you can keep your head when all about you
+    Are losing theirs and blaming it on you,
+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 by 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 bear to hear the truth you've spoken
+    Twisted by knaves to make a trap for fools,
+Or watch the things you gave your life to, broken,
+    And stoop and build 'em up with worn-out tools:
+
+If you can make one heap of all your winnings
+    And risk it on one turn of pitch-and-toss,
+And lose, and start again at your beginnings
+    And never breathe a word about your loss;
+If you can force your heart and nerve and sinew
+    To serve your turn long after they are gone,
+And so hold on when there is nothing in you
+    Except the Will which says to them: "Hold on!"
+
+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 the Earth and everything that's in it,
+    And - which is more - you'll be a Man, my son!
