IF

If can keep your head when all around you are losing theirs and blaming it on you
If you can trust yourself when everyone doubts you but make allowance for their doubting too
If you can wait and not be tired of waiting
Or being lied to and not deal in lies
Or being hated on and not giving way to hating
And yet don’t look too good nor talk to 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 these two impostors 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 get broken and stoop to build them up with worn-out tools
 
If you can make one heap of all your winnings and risk it in one turn of pitch-and-toss and lose and start again at your beginnings and never 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 when there is nothing in you except the will which says to say 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 everyone counts on 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
 
-Rudyard Kipling
