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, beinglied about, don't deal in lies,
Or, being hated, don't give way to hating,
  Andyet don't look too good, nor talk too wise;

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 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 talk with crowds and keep your virtue,
  Or walk with kings--not 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!
