Few Lines By Rudyard Kipling

A few lines from If'- one of many poems by Rudyard Kipling:

If you can dream--and not make dreams your master,
If you can think--and not make thoughts your aim;
If you can talk with crowds and keep your virtue,
Or walk with kings--nor lose the common touch,
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
Yours is the Earth and everything that's in it,
And--which is more—you ll be a Man, my son!
