-Rudyard Kipling
        
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!
