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 make one heap of all your winnings
And risk it all on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breath a word about your loss;
Yours is the Earth and everything that's in it,
And which is more you'll be a Man, my son!
~
Rudyard Kipling
