It is the job that you must approach with modesty,for some of what is thought to be knowledge today will be considered mistaken assumptions tomorrow.But humility and critical thinking, when combined with courage and determination, are indispensable qualities of leadership.It is said that all work that is worth doing is done in faith.Today, at this ceremony of cherished memory and shared resolve,let us each embrace the faith that every challenge surmounted by our energy;every problem solved by our wisdom; every soul awakened by our passion;and every barrier to justice brought down by our determinationwill ennoble our own lives, inspire others, and explode outward the boundaries of what is achievable on this earth.To the Class of 2015, I say again, "congratulations."And thank you so much for making me a part of your remarkable class.
