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,
...
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!'
...
Yours is the Earth and the silver in it,
And - which is more - you'll be a Man my son!
