If

If you can keep your head when all about you are losing theirs and blaming it on you...

If you can meet with Triumph and Disaster and treat those two imposters just the same...

If you can force your heart and nerve and sinew to serve your turn long after they are gone...

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!
