Success depends almost entirely on how effectively you learn to manage the game's two ultimate adversaries: the course and yourself.
I have found that the players who have played in that game really do have respect for their adversaries.
We have treated our most serious adversaries such as Iran and North Korea in the most juvenile manner - by giving them the silent treatment. In so doing we have weakened not strengthened our bargaining position and our leadership.
On our plane knowledge and ignorance are the immemorial adversaries.
Above all we must realize that no arsenal or no weapon in the arsenals of the world is so formidable as the will and moral courage of free men and women. It is a weapon our adversaries in today's world do not have.
