Steel

“To do for yourself the best that you have it in you to do—to grit your teeth and clench your fists in order to survive the world at its harshest and worst—is, by that very act, to be unable to let something be done for you and in you that is more wonderful still. The trouble with steeling yourself against the harshness of reality is that the same steel that secures your life against being destroyed secures your life also against being opened up and transformed.”
~Frederick Buechner
