IF
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, 
Butmake 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'tgive 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 notmake thoughts your aim; 
If you can meet with triumph and disaster 
And treat those two imposters just the same; 
If you can bear to hear the truthyou'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 wornouttools;
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 
Andnever breath 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 whenthere 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 - norlose 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 unforgivingminute 
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
