If by Rudyard Kipling - A poem for change

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 imposters 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 them 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
