Tranquil courage...................................

     When we aim high, pressure and stress obligingly come along for the ride.  Stuff is going to happen that catches us off guard, threatens or scares us.  Surprises (unpleasant ones, mostly) are almost guaranteed.  The risk of being overwhelmed is always there.
      In these situations, talent is not the most sought-after characteristic.  Grace and poise are, because these two attributes precede the opportunity to deploy any other skill.  We must possess, as Voltaire once explained about the secret to the great military success of the first Duke of Marlborough, that "tranquil courage in the midst of tumult and serenity of soul in danger, which the English call a cool head."
