If you can keep your wits about you while all others are losing theirs, and blaming you. The world will be yours and everything in it, what's more, you'll be a man, my son.
If you can meet success and failure and treat them both as impostors, then you are a balanced man, my son.
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;!
Take up the White Man's burden -- send forth the best ye breed -- go, bind your sons to exile to serve your captives need.
