"If" by Rudyard Kipling

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;

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 imposters 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 the things you gave your life to broken,

And stoop and build 'em up with wornout tools;

If you can make one heap of all your winnings

And risk it on one turn of pitch-and-toss,

And lose, and start again at your beginnings

And never breathe a word about your loss;

If you can force your heart and nerve and sinew

To serve 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 my son!

This poem is very famous. Obviously being a hard core runner (hard core runner should probably be defined but for now I feel a lot of people can be hard core runners as long as they take running seriously enough to schedule their life around their runs for a good majority of their time), I think the ending of this poem is great. The last line sometimes has popped up randomly in the middle of a long run and therefore fits the bill completely of what this blog is about.
