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 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 !

-       Rudyard Kipling
