Part of the 2009 Commencement speech: There is no such thing as a self-made man or woman. Never was, never will be. We are all, as were those in whose footsteps we follow shaped by the influence and examples of countless other-parents, grandparents, friends, rivals. And by those who wrote the music that moves us to our souls, those whose performance on stage or on the playing field took our breaths away, those who wrote the great charters which are the bedrock of our system of self-government. And so many who, to our benefit, struggled and suffered many times of trouble and grave uncertainty. And by teachers...I want to stress as emphatically as I can the immeasurable importance of teachers.
