Rudyard Kipling

/If...
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 you
If you can wait and not be tired by waiting or being lied about, don't
deal in lies or being hated, don't give way to hating and yet don't look
too good, nor talk too wise

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 bear to hear the truth you've spoken twisted by knaves to
make a trap for fools or watch things you give you life to, broken and
stoop and build'em up with worn-out tools

If you can make one heap of all your winnings and risk it all on one
turn of pitch-and-toss and lose, and start again at your beginnings and
never breath a word about your loss
If you can force your heart and nerve and sinew to server 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!"

If you can talk with crowds and keep your virtue or walk with Kings -
nor lose the common touch
If neither foes nor loving friends can hurt you
If all men count with you, but none too much
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!
