Letra de 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 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 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!
